Take two model portfolios: one holds stocks and gold; the other holds stocks and long-term U.S. government bonds.

On Tuesday, September 1, the stock-gold mix fell 1.58% from the previous close. The stock-bond mix lost 0.58%.

Imagine you added gold to your stocks because you wanted some protection when stocks fell. Now your mix is losing more than the stock-bond mix. “Wasn’t the gold supposed to help? Maybe I picked the wrong mix.” If you’re holding stocks and bonds instead, you might feel relieved: “At least I didn’t lose as much.” One day doesn’t tell you which portfolio is better. But it can make switching feel urgent.

That doubt is what we’re following this week. What makes it hard to stick with a choice when another one looks better? We’ll follow the same two portfolios through a recovery and another fall, and see how the urge to switch can fade and come back before you know how the week ends.

Tuesday, before the recovery

The stock-gold mix is called Stock-Gold 60/40. The stock-bond mix is Classic 60/40. By Tuesday’s close, the stock-gold mix was down 1.76% for the week so far; the stock-bond mix was down 0.93%. Both were losing money. One was losing less.

The two mixes invite different thoughts. With stocks and gold, it’s “Should I switch to the one that’s holding up better?” With stocks and bonds, it’s “Maybe this will keep cushioning the fall.” One loss makes you question your choice. The smaller loss makes it easier to trust yours, perhaps more than a single day deserves.

What we knew on Tuesday

Two reports came out at 10:00 a.m. ET on September 1, before that day’s close. But the daily returns start at the previous close, so they also include overnight moves and price changes before those reports arrived.

The Bureau of Labor Statistics’ July 2026 JOLTS report counted 7.3 million job openings, little changed. The Institute for Supply Management’s August 2026 manufacturing report showed slower growth: its PMI fell to 54.6 from 55.6 in July, but stayed above the 50 mark that separates expansion from contraction. Its prices index stayed at 71.1. Manufacturers were still paying higher input prices; the index itself hadn’t risen from July.

The news wasn’t a simple good-or-bad signal for these assets. A growing manufacturing sector can brighten the outlook for company profits. Rising input costs can squeeze those profits and change expectations for interest rates. If investors demand higher yields, long-term Treasury prices can fall, and investors may be willing to pay less for stocks.

Even when you’re counting on gold for protection, it faces a push and pull: inflation concerns can support demand, while higher yields make it more costly to hold an asset that pays no interest. These stock, bond, and gold channels are ways the news can matter, not proof of what moved the two portfolios that day.

What changed after Tuesday

Now look at the whole week, not just Friday’s result. The chart starts all five models from the same reference point, the August 28 close, and follows the next five trading days.

By Thursday’s close, both mixes had recovered their losses for the week. Stock-Gold 60/40 was up 0.39% from the previous Friday’s close; Classic 60/40 was up 0.10%. Then Friday’s fall put both back below that starting point. The final weekly numbers miss that stretch of recovery.

The daily table shows where those turns happened. Each return is measured from the previous recorded close, so you can see the two days of gains separately from Friday’s fall.

Both mixes rose on Wednesday and Thursday, then fell on Friday. Stock-Gold 60/40 lost 0.48% on Friday; Classic 60/40 lost 0.18%. It wasn’t one uninterrupted slide. There was a recovery in between.

As the stock-gold mix recovers, you can breathe a little easier: “Maybe I don’t need to switch after all.” Friday’s drop can bring the doubt back. In the stock-bond mix, the recovery can feel reassuring too, until another loss reminds you that losing less isn’t the same as being protected from losses. On Tuesday, you didn’t yet have Wednesday, Thursday, or Friday to look at.

The five models behind the scoreboard

UnclAlpha’s Portfolio Lab: Live follows five fixed model portfolios, not actual accounts. These are their target weights. Market moves can shift the weights between rebalances.

• 100% QQQ: QQQ only, bought and held.

• 100% S&P 500: SPY only, bought and held.

• Stock-Gold 60/40: SPY 48 percent, QQQ 12 percent, GLD 40 percent.

• Classic 60/40: SPY 60 percent, TLT 40 percent.

• Harry Browne’s Permanent Portfolio: SPY, TLT, SHY, and GLD at 25 percent each.

The two mixes we’ve been following both aim to keep 60 percent in stocks. But the stocks aren’t the same: the stock-gold mix holds SPY and QQQ, while the stock-bond mix holds only SPY. So gold versus long-term Treasuries isn’t the only difference. This comparison can’t isolate how much of the return came from choosing gold instead of bonds.

Small weekly changes after an uneven path

The scoreboard puts the week’s result beside the longer record, using the same reporting periods for all five models. Calmar helps compare the annualized return with the biggest peak-to-trough loss along the way. It divides that return by the size of that loss over the same period.

Weekly returns ranged from −0.19% for the Permanent Portfolio to +0.35% for QQQ. Stock-Gold 60/40 lost 0.10%; Classic 60/40 lost 0.09%. Their Calmar ratios over the full model history were 0.34 and 0.30, respectively. Those small weekly losses look very different from Tuesday’s larger losses.

Ahead over the year, down more on Tuesday

What happens when we look back a full year? This chart uses the same one-year period for all five models. It gives us a longer comparison, instead of asking one day to settle the question.

Over the year ending September 4, Stock-Gold 60/40 gained 23.63%, compared with 11.32% for Classic 60/40. The mix that did better over the year was also the one that lost more on Tuesday. Both facts belong in the story. Neither would have told you what would happen next.

What was difficult to hold

As the stock-gold mix recovers, the urge to switch can fade. You get some breathing room. When it falls again, the doubt can return. With the stock-bond mix, the recovery can build your confidence, until another loss reminds you that the cushion you felt wasn’t complete protection.

Put yourself back in Tuesday’s Stock-Gold 60/40 mix. Classic 60/40 wasn’t an abstract alternative. It was right there, losing less. That’s what could make you want to switch. If you’re holding Classic 60/40, you can take comfort in the smaller loss without knowing whether you’ve made the better choice. Friday’s result doesn’t tell you what Tuesday felt like. That’s why we keep the day-by-day record: it preserves the choice in front of you before you knew the ending.

Audit receipt

This week’s frozen model-data snapshot has this SHA-256 fingerprint: fbc3bcd30286dd44ed74e77c56b46c68a9f927403131f863a48bdca30d555613. It identifies the data used here, not actual trades.

The week ahead

For September 7-13, the BLS calendar lists two inflation reports: August producer prices (PPI) on Thursday, September 10, and August consumer prices (CPI) on Friday, September 11. Both are scheduled for 8:30 a.m. ET. We’ll watch the gold and Treasury holdings in Stock-Gold 60/40, Classic 60/40, and the Permanent Portfolio around those releases. These are dates to watch, not forecasts of which way prices will move or how much. At our September 6 research cutoff, neither the reports nor the market reactions were known.

Method and limits

Data cutoff: 2026-09-04. The models use daily closing prices adjusted for distributions, with those distributions reinvested. Each model starts with a hypothetical $10,000 on January 1, 2005; the first date with data for all five is January 3. Single-asset models buy and hold. Multi-asset models rebalance once a year, using the registered 0.1% drift threshold. Returns for periods shorter than a year are cumulative; the longer reporting periods use annualized returns. Maximum drawdown is the biggest peak-to-trough loss, not an annualized figure.

The $10,000 is a common starting amount, or normalization base. It doesn’t reset at the start of each day. A different starting amount scales the dollar values proportionally, by that amount divided by $10,000. Percentage returns, maximum-drawdown percentages, and Calmar ratios remain unchanged. The dates matter too: this record leaves out QQQ’s 2000-02 crash, but includes a strong period for gold and a severe bond bear market. Those choices limit what we can take from the results. The gold holding is GLD; a backtest using spot gold or gold futures isn’t directly interchangeable.

This issue asks whether diversification failed when the portfolio built for protection fell behind. The same Friday asked for two different kinds of patience from a gold-heavy portfolio and a classic stock-and-bond mix. To answer, we will first name the two fixed models, then separate Friday’s close from the full week and the longer record.

To test that question consistently, Portfolio Lab tracks two fixed hypothetical models rather than anyone’s live account. The gold-heavy line is called Stock-Gold 60/40; the stock-and-bond line is Classic 60/40. The timing and direction line up, but daily data cannot tell us how much gold contributed to the first model’s move or declare either construction the winner. One close cannot establish superiority, and the later path was not knowable when that pressure appeared.

Here is the fuller information screen, after the question is clear. Chair Kevin Warsh said underlying inflation had not meaningfully improved (Federal Reserve). Reuters later reported that gold reversed lower as September rate-hike odds and the dollar rose. Confidence in inflation control could favor risk assets, while higher expected policy rates and a stronger dollar could pressure long Treasuries and gold. The report was directionally consistent with pressure on the gold sleeve, but daily data cannot isolate its contribution to either portfolio.

The fixed public roster is unchanged: 100% QQQ; 100% S&P 500; Stock-Gold 60/40; Classic 60/40; Harry Browne’s Permanent Portfolio. For today’s comparison, the important difference is the defensive sleeve: the former carries more gold, while the latter carries more long Treasuries. That construction difference is observable even though the session move cannot be assigned to one event.

Scoreboard

The scoreboard compares the five fixed public models on the same registered receipt. Alongside return windows and maximum drawdowns, it shows the since-inception Calmar ratio: annualized return divided by maximum drawdown. Within this metric, a higher value means more annualized return per unit of maximum drawdown. Every value comes from the accepted tracker output, not from chart inspection.

Now the clocks line up. For the full week ending 2026-08-28, Stock-Gold 60/40 returned -1.03%, while Classic 60/40 returned +0.67%. Their since-inception Calmar ratios were 0.3454 and 0.2963, respectively. Friday explains the immediate discomfort; the weekly and longer records answer different questions.

Longer Record

The trailing-one-year view asks a different question from the weekly scene: what did each fixed construction deliver over one common recent window, using the same adjusted-close, distribution-reinvested method.

Over the accepted trailing year, Stock-Gold 60/40 returned +25.71%, while Classic 60/40 returned +11.61%. The one-year gap gives the weekly loss pressure context, but it does not turn the latest close into a verdict.

Weekly Path

The weekly path view starts from the 2026-08-21 baseline and follows each recorded session through 2026-08-28, so the reader can see how a still-positive balanced line and a negative gold-heavy line reached different Friday screens.

By the Friday close, Stock-Gold 60/40 was down 1.03% for the week, while Classic 60/40 was up 0.67%. The cross-portfolio week-to-date spread on the selected session was 1.70%, which is the path split behind the holder question.

The daily table checks the same decision clock more tightly: it asks whether the Friday move was a broad down day and how much the two selected constructions differed on that single close.

On 2026-08-28, all five public lines closed lower. The selected pair still looked different: Stock-Gold 60/40 fell 1.43%, while Classic 60/40 fell 0.25%, leaving one line below the week baseline and the other above it.

What This Week Actually Taught

This week, a diversifier became the visible source of drag while another balanced construction still looked positive. That is the uncomfortable lesson: diversification does not remove disappointment. It changes where disappointment can appear, and therefore what kind of patience a fixed rule may demand.

So, did the wrong portfolio get chosen? This week cannot answer that. Stock-Gold 60/40 created visible loss pressure by finishing below the prior close, while Classic 60/40 created giveback anxiety inside a still-positive week. The contrast shows different holder pressure, not proof that either construction is superior. The next scheduled observations are listed below; the same fixed rules will record what follows without predicting the result.

Method And Limits

Data run through 2026-08-28. Portfolio Lab uses a hypothetical $10,000 starting amount from 2005-01-01, daily adjusted close with distributions reinvested, single-asset buy and hold, and annual rebalancing for multi-asset lines with a 0.1% drift threshold.

For another initial capital, multiply each dollar balance by the amount divided by $10,000. Dollar values scale proportionally; percentage returns, maximum drawdown percentages, and Calmar ratios stay the same.

This is educational model tracking with no actual holdings and not personalized investment advice. The event restores the information environment; it does not explain the portfolio move beyond the accepted mapping ceiling. The holder experience is a path-supported hypothetical scenario, not evidence of what real people did.

The tracker window starts after QQQ’s 2000-02 crash and includes a strong gold cycle and a severe bond bear market, so history should be read with those limits. Past performance does not guarantee future results. Full disclaimer: https://unclalpha.com/disclaimer

Wednesday closed with the kind of screen that can make a long-term plan feel suddenly wrong. QQQ slipped another 0.20%, its third decline in a row, and sat 2.05% below the prior Friday. Stock-Gold 60/40 rose 1.50% and crossed back to a 0.40% weekly gain. Two hours before the close, the Federal Reserve had released its July 28–29 meeting minutes. One reading rule matters for everything that follows: Portfolio Lab compares the paths that holders saw; it does not assign a daily move to one headline or forecast the next one.

The minutes showed that three voting members had favored a quarter-point rate increase. That made the disagreement inside the Fed concrete. Higher-for-longer rates can be uncomfortable for growth stocks whose valuations depend heavily on profits far in the future, while inflation uncertainty can be relatively friendlier to gold. That helps explain why the two portfolios carry different sensitivities—not why prices moved exactly as they did that afternoon.

The emotional comparison was still real. A hypothetical QQQ holder could see the week’s lagging line and feel regret: the neighboring portfolio had just supplied the buffer QQQ lacked. A hypothetical Stock-Gold 60/40 holder could feel relief and begin treating one rebound as proof that the buffer would keep working. Both temptations asked one close to answer a long-term question. At Wednesday’s close, Thursday and Friday were still unknowable.

Was this gap big enough to matter?

Resetting all five portfolios to the same prior-Friday baseline shows when the experiences separated. The question is not merely which line finished first, but how far apart the fixed rules looked while a holder still had to decide whether to stay with one.

By Friday, Stock-Gold 60/40 was up 1.01% while QQQ was down 2.41%—a 3.42 percentage-point gap between the week’s leader and laggard. The S&P 500 line finished down 1.37%, Classic 60/40 down 0.87%, and the Permanent Portfolio up 0.96%. A gap that visible is exactly why switching can feel urgent; it is large enough to change the holder experience before it is large enough to settle the long-term choice.

The daily table narrows the comparison to Wednesday, when QQQ was the only declining public line. That same-clock view shows why the contrast felt sharper than the weekly totals alone suggest.

On August 19, QQQ fell 0.20%. The S&P 500 line rose 0.21%, Stock-Gold 60/40 rose 1.50%, Classic 60/40 rose 0.74%, and the Permanent Portfolio rose 1.40%. The screen did not merely show QQQ losing; it showed every alternative in the fixed experiment moving the other way.

Thursday made the pressure less comfortable, not the earlier choice more obvious. QQQ declined again, which could intensify the urge to abandon it. Stock-Gold 60/40 surrendered part of Wednesday’s rebound but remained just above its weekly baseline, which could weaken the confidence created by the buffer. The emotional bill changed with the next close; the portfolio rules did not.

Were these portfolios built to feel the same?

Portfolio Lab follows the same five models under the same rules every week: 100% QQQ; 100% S&P 500; Stock-Gold 60/40; Classic 60/40; and Harry Browne’s Permanent Portfolio. The first is concentrated growth equity. The selected stock-gold mix combines broad U.S. equity, growth equity, and gold. Wednesday exposed the trade-off embedded in those designs: concentration delivered more of the week’s growth-equity pressure, while the mixed construction supplied a visible buffer.

What changes when we zoom out to one year?

The trailing-one-year chart puts the week inside a common recent window. If Wednesday was only an isolated impression, the longer paths might tell a different story; if the construction trade-off persisted, both return and discomfort should appear in the record.

Over the accepted trailing year, Stock-Gold 60/40 returned 29.96%, versus 27.25% for QQQ. Its maximum drawdown over that same window was 12.61%, versus 11.96% for QQQ. In this particular year, the mixed portfolio finished with slightly more return and a slightly deeper worst decline. “More diversified” did not translate into a guaranteed shallower path; the trade-off changed with the window.

Does the longer history change the answer?

The scoreboard extends the comparison across the registered history. Calmar divides annualized return by the magnitude of maximum drawdown: a ratio of 1 would mean annualized return matched the deepest historical decline. It is best read as a compact description of one return-and-pain history, not as a grade for the portfolio.

Since 2005, QQQ’s Calmar ratio was 0.29 and Stock-Gold 60/40’s was 0.35. In plain English, the mixed portfolio’s historical annualized return held up somewhat better relative to its deepest drawdown. QQQ produced the higher annualized return—15.10% versus 12.18%—but also the deeper maximum drawdown, 52.96% versus 35.07%. The numbers describe two different bargains with risk; they do not reduce either one to a winner or loser.

This week’s lesson

Portfolio construction changes the shape of temptation. Concentration can make a losing week feel intolerable; a buffer can make the neighboring portfolio look suddenly obvious. This week asked hypothetical holders to endure the moment when that emotional contrast began masquerading as long-term evidence.

Closing answer

So, did Wednesday’s safer-looking path justify switching? No single close did. QQQ’s concentrated growth exposure created regret and switching pressure as it lagged, while Stock-Gold 60/40’s equity-and-gold mix created buffer relief. The lesson was not which portfolio won. It was how quickly one week could make a long-term plan feel wrong—and why repeating the same fixed experiment helps us recognize that temptation before acting as if it were proof.

That comparison raises three questions:

1. What does this gap mean for someone following the Permanent Portfolio?

2. Was the gap simply a macro story?

3. Did the Permanent Portfolio fail—or did Thursday expose the price of protection?

1. What does the gap mean? A holder looking at that screen asks the obvious question: “My Permanent Portfolio barely moved while QQQ jumped. Did I choose the wrong portfolio?” Thursday rewarded QQQ’s concentration and made diversification feel costly. For someone following the quieter rule, the temptation was to treat one sharp recovery as evidence that protection had become a mistake. For someone following QQQ, the pressure was different: protect the gain that had just returned.

2. Was the gap simply a macro story? The evidence supports a rate-pressure channel, but not a single-event explanation. July producer prices were unchanged at the headline level, initial unemployment claims increased, and contemporaneous reporting citing CME FedWatch recorded lower odds of a September rate increase than two days earlier. Lower rate pressure offered a friendlier channel for QQQ. The daily evidence cannot pin the gap on any single release. The third question stays open. Answering it means testing Thursday’s impression against construction, the longer record, and the full weekly path—and at Thursday’s close, none of that later path was available yet.

The fixed five-portfolio experiment

Start with construction. Portfolio Lab follows the same five portfolios under the same rules every week: 100% QQQ; 100% S&P 500; Stock-Gold 60/40; Classic 60/40; and Harry Browne’s Permanent Portfolio. QQQ is concentrated growth equity. The Permanent Portfolio divides capital equally among broad U.S. equities, long Treasuries, short Treasuries, and gold. Thursday displayed the difference between those designs; the next tests ask whether that difference amounts to failure.

The scoreboard

The first test uses the common history. The scoreboard compares return, maximum drawdown, and Calmar—the annualized return divided by the worst historical drawdown. A Calmar ratio of 1 would mean the annualized return matched the magnitude of that worst decline.

QQQ’s since-inception Calmar ratio was 0.29, compared with 0.40 for the Permanent Portfolio. Both were below 1: each portfolio’s annualized return was smaller than its worst peak-to-trough loss. QQQ accumulated more return in this history; the Permanent Portfolio paired its lower return with a shallower maximum drawdown.

The second test shortens the clock. Was the trade-off between growth and protection already visible over the same recent twelve months for all five portfolios? The chart shows the return paths on a common indexed basis. The numbers below add maximum drawdown from the same twelve months.

Over that year, QQQ returned 26.66%, versus 14.43% for the Permanent Portfolio. That return gap is only half the comparison. Over the same window, QQQ’s maximum drawdown was 11.96%, versus 7.71% for the Permanent Portfolio. Recent history had already made both sides of the trade-off visible: the more concentrated portfolio delivered the larger gain and the deeper drawdown. Thursday compressed the return side of that longer contrast into a single, emotionally sharper close.

The week under the microscope

The third test restores the sequence that weekly totals hide. Resetting every portfolio to the same prior-Friday baseline shows when the two experiences separated before the week had finished.

The separation arrived on August 13. QQQ gained 1.16% and completed a 1.89% recovery from its August 11 trough. The Permanent Portfolio was essentially flat. That was the moment last week’s comfort acquired a visible cost.

The daily table completes that test: which portfolio rose or fell on each close, and what happened after Thursday’s temptation appeared?

QQQ finished the week up 1.11%. The Permanent Portfolio finished up 0.11%. The weekly gap remained, but neither endpoint alone shows what each rule asked its follower to endure on the way there.

Friday trimmed both weekly gains, but one later close could not decide whether protection had failed. A Permanent Portfolio follower could still question the muted recovery; a QQQ follower could now feel pressure to protect Thursday’s rebound. The later close changed the pressure, but it did not make Thursday’s choice obvious in advance.

This week’s lesson

Diversification changes the shape of disappointment. During weakness, a buffer can make a concentrated decline easier to bear. During a sharp rebound, that same buffer can look like dead weight. The rule stays still while the emotional bill changes with the path.

Closing answer

So, did the Permanent Portfolio fail? No. What happened was narrower: its multi-asset buffer lagged while QQQ’s concentrated growth exposure rebounded. The value of repeating the same fixed experiment each week is seeing the cost of protection change while the rules stay still. That is why last week’s comforting buffer could become this week’s source of regret.

  Portfolio Lab will add the resulting portfolio paths only after those observations exist.

Method and limits

Data run through 2026-08-14. Each historical model begins with a hypothetical $10,000 on 2005-01-01, with the first common observation on 2005-01-03. Within this model, a different starting amount simply scales every dollar value proportionally. Multiply each dollar value by your chosen starting amount divided by $10,000; percentage returns, maximum-drawdown percentages, and Calmar ratios remain unchanged. Returns use daily adjusted closes with distributions reinvested. Single-asset portfolios are buy and hold; multi-asset portfolios rebalance annually under a 0.1% drift threshold. Returns under one year are cumulative, while longer periods are annualized. The common history excludes QQQ’s 2000–02 crash, includes a strong gold cycle and a severe bond bear market, and uses GLD rather than spot gold or gold futures.

Portfolio Lab is educational model tracking with no actual holdings, and it is not personalized investment advice. Historical and hypothetical results do not promise safety or future returns. Full disclosure: https://unclalpha.com/disclaimer.

From January 3, 2005 through July 31, 2026, a hypothetical $10,000 in 100% QQQ grew to $202,130. It was the highest ending value among Portfolio Lab’s five model portfolios.

But the comparison starts after QQQ’s roughly 83% dot-com collapse in 2000-02. Even inside the later window, QQQ suffered a 53.0% maximum drawdown and once took 1,136 calendar days to recover its prior peak. The ending value is real within the model. It is not the whole record.

Historical model, not an account record or a recommendation. Data run through July 31, 2026; a future decline could be larger than any shown here.

Why the worst crash is missing

The start date was not chosen to flatter QQQ. It was chosen so all five Portfolio Lab portfolios could begin on the same clock.

GLD is the limiting asset. Because the gold ETF launched in late 2004, 2005 is the first year-start after every ETF used across the five portfolios existed. That makes the comparison consistent—and removes QQQ’s worst historical crash from view.

So this is a recovery-era sample, not QQQ’s complete history. It includes the global financial crisis, the COVID crash, the 2022 rate shock, and a long growth run. An earlier QQQ study beginning in 1999 includes the dot-com collapse, but its headline figures are not interchangeable with this five-portfolio comparison.

That distinction is the first lesson. A backtest window is not packaging. Change the start date and you can remove a crisis, raise an annualized return, or change a risk-adjusted ranking without changing the portfolio itself.

Method in plain English

“Frozen” means we stopped the clock on July 31, 2026 so the evidence will not move while you inspect it. Each line starts with $10,000. QQQ and SPY are held without rebalancing; distributions are reinvested. The three mixed-asset portfolios rebalance annually under the Lab’s fixed rule. Modeled trading costs are included; taxes, inflation, and investor cash flows are not. Full protocol: [METHOD_URL]

QQQ versus the broad-market benchmark

SPY gives the result a useful anchor. Both lines use the same dates, hypothetical starting value, reinvested distributions, cost model, and buy-and-hold rule.

• 100% QQQ: 20.2x ending multiple, 15.0% annualized return, -53.0% maximum drawdown, and 0.28 Calmar.

• 100% SPY: 9.1x ending multiple, 10.8% annualized return, -54.7% maximum drawdown, and 0.20 Calmar.

QQQ compounded faster in this window. The surprising line is maximum drawdown: SPY’s was slightly deeper. That does not establish that QQQ is safer. It shows why a selected sample can defeat a familiar intuition.

Calmar is simply annualized return divided by the absolute maximum drawdown. It places growth beside the deepest historical fall; it does not declare a universal winner.

The path asked more than one question

An endpoint cannot show when the pressure arrived or how long it lasted. Three declines in the same asset created three different holding problems:

• 2008 financial crisis. The model lost 51.1% in the fixed stress window, reached a 53.0% maximum drawdown, and did not recover its prior peak until December 10, 2010. The question in the moment: Could you stay with the rule after years below the old high?

• 2020 COVID crash. The model lost 27.9% in the fixed stress window, reached a 28.5% maximum drawdown, and recovered its prior peak by June 3, 2020. The question in the moment: Could you sit through a fast fall without knowing the recovery would also be fast?

• 2022 rate-hike cycle. The model lost 34.3% in the fixed stress window; the broader episode recovered on December 13, 2023. The question in the moment: Could you separate a difficult cycle from evidence that the rule had failed?

Those are holder scenarios, not survey results. At each low, the later recovery was still unknown.

Maximum drawdown measures the depth of the hole. Recovery time measures how long the old high stayed out of reach. QQQ’s longest episode in this record lasted 1,136 calendar days from peak to recovery. You had to live through both dimensions before the endpoint existed.

What QQQ contributes to the five-portfolio experiment

The five fixed lines are 100% QQQ, 100% S&P 500, Stock-Gold 60/40, Classic 60/40, and Harry Browne’s Permanent Portfolio. QQQ is the growth extreme. The other lines provide a broad-equity benchmark or exchange some equity exposure for gold and Treasury allocations.

The point is not to crown one permanent winner. It is to see what changes when the rule changes. In this particular window, QQQ delivered the highest ending value and annualized return. Other portfolios produced shallower declines or stronger return-to-drawdown ratios.

For QQQ, the conclusion is narrower and more useful than “it won.” The endpoint describes where this model finished. The 2005 start explains which history it excludes. The path shows what had to happen before the finish became visible.

Never read a backtest endpoint without its path and its window.

Wednesday delivered the kind of macro news that refuses a clean bullish-or-bearish label. The July ISM Services report showed stronger activity, contracting employment, and higher input prices. Stronger activity could favor equities; hotter costs could pressure long Treasuries and rate-sensitive growth stocks. By the close, however, QQQ—our concentrated Nasdaq-growth line—was down 0.90%, while the Permanent Portfolio—split equally among U.S. stocks, long Treasuries, short Treasuries, and gold—was up 0.96%. The news made both portfolios worth watching; it does not establish why either daily return occurred.

That is when the dangerous, familiar thought appears: “My QQQ just fell while the Permanent Portfolio rose. Did I choose the wrong portfolio?” One close cannot answer that. A hypothetical QQQ holder was watching part of a still-positive week disappear. A hypothetical Permanent Portfolio holder was watching diversification provide a one-day buffer. The contrast was real; superiority was not established, and Thursday was still unknowable.

The useful question is what happened to each temptation when the next close arrived—and what the full record says once we separate one emotional session from the rule each portfolio was built to follow.

Thursday made the QQQ holder’s urge to protect the remaining gain harder to dismiss: another lower close could make switching toward the portfolio that had looked safer feel prudent. The Permanent Portfolio holder then faced the mirror-image pressure. Its own lower close could turn Wednesday’s relief into doubt that the buffer had been overread. Neither reaction would be irrational. Neither Thursday outcome was available on Wednesday, so hindsight cannot turn the earlier choice into an obvious mistake.

This week’s lesson

Portfolio construction does not remove discomfort; it changes its sequence. Concentration can make an early gain feel fragile. Diversification can provide relief and then disappoint when the cushion does not repeat on command. Before treating one convenient close as a verdict, separate two questions: Did the portfolio’s rule change, or did only the latest path—and your reaction to it—change?

The fixed five-line experiment

Portfolio Lab keeps the same five educational model lines: 100% QQQ, buy-and-hold growth equity; 100% S&P 500, the broad-equity benchmark; Stock-Gold 60/40, combining SPY, QQQ, and gold; Classic 60/40, combining SPY and long Treasuries; and Harry Browne’s Permanent Portfolio, combining SPY, long Treasuries, short Treasuries, and gold in equal sleeves. Fixing the rules lets us study different paths without redesigning a portfolio after seeing the result.

The scoreboard

The scoreboard asks a broader question than “Who is ahead?” Across the same registered windows, how much annualized return came with how much maximum drawdown? Calmar—annualized return divided by absolute maximum drawdown—puts those two quantities on one line, but it is a comparison lens, not a universal verdict.

Since the common 2005 start, QQQ shows the stronger annualized return of the pair at 15.20%, but also the deeper maximum drawdown at −52.96%, producing a Calmar of 0.29. The Permanent Portfolio shows 7.36% annualized with an −18.38% maximum drawdown and a 0.40 Calmar. That does not make either portfolio “better.” It makes the trade-off visible: more historical growth arrived with a much harsher historical fall.

The trailing-one-year chart narrows the clock. It compares all five models over the same recent window, with distributions reinvested and without annualizing a period shorter than one year. This view answers what happened recently, not what should happen next.

Over that common trailing year, QQQ led at 27.61%, followed closely by Stock-Gold 60/40 at 26.97%. The S&P 500 returned 23.62%, the Permanent Portfolio 14.08%, and Classic 60/40 13.50%. The ordering explains why a QQQ holder could still have the stronger recent result while feeling more pressure on Wednesday. It does not turn the ranking into a forecast.

The week under the microscope

Weekly totals hide the order in which gains and setbacks arrived. Rebased to the prior Friday close, the weekly path asks when the temptation to protect, switch, or declare victory actually appeared—not merely where the two lines finished.

QQQ reached +5.21% for the week on Tuesday, slipped to +4.26% on Wednesday and +3.87% on Thursday, then finished at +5.09% on Friday. The Permanent Portfolio moved from +2.34% on Wednesday to +2.12% on Thursday and +2.95% on Friday. The path shows why Wednesday’s switching impulse could intensify on Thursday even though Friday eventually left both models positive.

The daily table provides the audit beneath that story. It lets a reader compare every model on the same close and verify whether the apparent buffer belonged to one portfolio, several mixed-asset lines, or the whole five-line set.

Wednesday split the set: QQQ (−0.90%), the S&P 500 (−0.20%), and Classic 60/40 (−0.05%) declined, while Stock-Gold 60/40 (+1.24%) and the Permanent Portfolio (+0.96%) advanced. On Thursday all five declined; on Friday all five advanced. The buffer was therefore real but temporary—not a permanent property revealed by one close.

The week ahead: what to watch

Three official observation points fall inside the accepted window.

• The July Consumer Price Index is scheduled for August 12 at 8:30 AM ET.

• The Advance Monthly Sales for Retail and Food Services report for July is scheduled for August 14 at 8:30 AM ET.

• The New Residential Construction report for July is scheduled for August 18 at 8:30 AM ET.

Portfolio Lab will record the fixed paths after the releases exist. Their contents and any market responses were unknown at the research cutoff.

Method and limits

Data cutoff: 2026-08-07. Each historical model starts with a hypothetical $10,000 on 2005-01-01, with the first common observation on 2005-01-03. The tracker uses daily adjusted closes with distributions reinvested. Single-asset lines are buy and hold; multi-asset lines rebalance annually under the registered 0.1% drift threshold. The window excludes QQQ’s 2000–02 crash and includes both a strong gold cycle and a severe bond bear market. Results using GLD are not directly comparable with work using spot gold or gold futures without an explicit bridge.

Portfolio Lab is educational model tracking with no actual holdings. It is not personalized investment advice, a trade instruction, or a promise of return, safety, or repeatability. The holder scenes are path-supported hypothetical scenarios, not evidence of what real people thought or did. Past performance does not guarantee future results.

Closing answer

Wednesday did not prove that the QQQ holder had chosen the wrong portfolio. It exposed the cost of living with a concentrated rule at the exact moment a diversified rule looked comforting. The practical question to carry forward is not “Which portfolio won today?” but “Did my evidence about the rule change, or am I reacting to the latest path?” A fixed weekly record is useful because it preserves that distinction before hindsight makes every decision look easier.

You do not need to invent a single price to make a backtest tell a different story.

Move the starting date past a crash. Replace an investable ETF with a longer but different gold series. Ignore trading costs. Change the score from ending wealth to a risk-adjusted ratio. Each choice can be defensible. Each can also change the apparent winner.

That is why the first question is not, “Which portfolio won?”

It is, “Which decisions were fixed before anyone looked at the result?”

Portfolio Lab: Live compares five hypothetical portfolios under one public protocol. The commitment is simple: no changing the portfolio rules after seeing how they performed.

Quick note: this is educational model tracking, not investment advice, an account record, or a recommendation. The Lab uses hypothetical total-return models. Historical drawdowns are report cards, not floors; a future decline can be larger.

A backtest can be honest and still answer the wrong question

A polished chart can be numerically correct while leaving its most important choices invisible.

Suppose one study begins after an asset’s worst collapse, while another includes it. Suppose one uses adjusted prices with distributions reinvested, while another uses price alone. Suppose one portfolio is rebalanced for free every month, while another pays modeled trading costs once a year.

The outputs may all be calculated correctly. They are still not answering the same question.

The Lab therefore treats the method as part of the result. The clock, vehicles, data treatment, cash-flow rule, trading assumptions, metrics, and correction policy all belong beside the performance numbers.

Seven questions to ask before you believe any backtest

1. What is the exact window?

The start date decides which crashes, recoveries, inflation regimes, and interest-rate cycles enter the record. “Long term” is not a date. A useful backtest states the first and last observation and explains why that boundary exists.

2. What could an investor actually have owned?

A spot index, futures series, mutual fund, and ETF can represent the same broad asset while producing different histories. Vehicle choice affects availability, distributions, fees, tracking, and the earliest fair comparison date.

3. Is this price return or total return?

A price chart can omit dividends and other distributions. The Lab uses adjusted-close data so distributions are reinvested in the model. That does not create an actual account; it makes the return definition explicit.

4. Are outside cash flows mixed into performance?

Deposits and withdrawals can change an account balance without saying anything about the portfolio’s underlying return. The Lab starts each model with the same hypothetical amount and adds no later cash flows. It reports time-weighted performance.

5. How are rebalancing and trading costs modeled?

Rebalancing can create trades, and trades are not frictionless. Frequency, drift rules, commissions, slippage, and market impact can all alter the path. A strategy rule without an execution rule is incomplete.

6. Which score decides the verdict?

Ending wealth, annualized return, maximum drawdown, volatility, Sharpe, and Calmar do not measure the same thing. If the winning metric changes after the results appear, the backtest can select its own champion.

7. Can the author quietly rewrite history?

A credible live record needs dated inputs, reproducible outputs, and visible corrections. Method changes should create a new version. They should not overwrite the old receipt.

The five fixed lines

The Lab is not a search for one universally best portfolio. It is a fixed bench of five deliberately different designs.

• 100% QQQ - QQQ 100%. The growth extreme.

• 100% S&P 500 - SPY 100%. The broad U.S. equity benchmark.

• Stock-Gold 60/40 - SPY 48%, QQQ 12%, GLD 40%. The Lab’s case-study allocation from its backtest research - not a textbook standard and not a recommendation.

• Classic 60/40 - SPY 60%, TLT 40%. The conventional stock-and-long-Treasury reference.

• Harry Browne’s Permanent Portfolio - SPY 25%, TLT 25%, SHY 25%, GLD 25%. The textbook four-part design published in 1981, spread across growth, deflation, cash-like stability, and gold.

The single-asset lines are buy and hold. The three multi-asset lines rebalance annually, subject to a 0.1% drift threshold. The roster and weights remain fixed from one weekly issue to the next.

The differences are the point. QQQ makes growth concentration visible. SPY supplies an equity control. Stock-Gold asks what happens when gold supplies the defensive sleeve. Classic 60/40 represents a familiar stock-bond balance. The Permanent Portfolio pushes diversification further.

Why the common clock begins in 2005

The hypothetical start is January 1, 2005, with the first common trading observation on January 3.

That boundary is not chosen because 2005 makes every portfolio look good. It is the first year-start after all investable ETFs used by the five public models existed. GLD sets the limiting date.

The choice creates a fair common clock, but it also creates a limitation: QQQ’s 2000-02 crash sits outside the tracker. This is a recovery-era QQQ sample, not QQQ’s complete history.

The same window contains a strong period for gold and an unusually severe bond bear market. Earlier studies that use spot gold or gold futures reach further back, but they are not directly interchangeable with this GLD-based tracker. GLD is an investable ETF with an approximately 0.40% expense ratio and tracking difference; those vehicle costs are part of why the histories are not interchangeable.

There is no neutral start date. There is only a disclosed one, with consequences the reader can see.

The frozen protocol

Every line begins with a hypothetical $10,000. No deposits or withdrawals follow.

Data. Daily adjusted close, with distributions reinvested. Tiingo is the primary source and yfinance is used as a cross-check.

Execution. Single-asset portfolios remain buy and hold. Multi-asset portfolios use annual rebalancing with a 0.1% drift threshold.

Modeled trading costs. Commission is $0.0005 per share with a $1.99 minimum, plus 0.010% slippage and 0.0050% market impact.

Return windows. One week, year to date, and one year are cumulative returns. Three years and since inception are annualized returns; since inception also reports the cumulative multiple.

Drawdown. Maximum drawdown measures the deepest observed fall from a previous peak. It does not predict the deepest possible future loss.

Volatility. Annualized variability of daily model returns. It describes dispersion, not the lived length of a recovery.

Calmar. Annualized return divided by the absolute maximum drawdown. No risk-free-rate assumption enters that calculation.

The protocol excludes taxes, investor-specific cash flows, account constraints, and individual execution. Those omissions narrow what the model can claim.

Why Calmar is the fixed verdict column

The weekly scoreboard needs one stable risk-adjusted comparison. The Lab uses Calmar because its ingredients are visible: annualized growth and the deepest historical drawdown.

Sharpe remains in the underlying data contract, using a constant 3% risk-free rate. It is not the fixed public verdict column. Its ranking can change with the chosen risk-free rate, measurement window, and asset vehicle - especially when gold histories differ.

Calmar is not “the best” measure. It is the declared measure. That distinction prevents the score from changing simply because another ratio produces a more convenient winner.

One dated example: different questions, different winners

In the frozen record through July 31, 2026, QQQ produced the highest ending value and annualized return. The Permanent Portfolio produced the highest Calmar ratio. Stock-Gold 60/40 sat between those two lines on ending value, annualized return, maximum drawdown, and volatility.

That is not a contradiction. Ending wealth rewards the largest terminal value. Calmar asks how much annualized growth appeared relative to the deepest observed fall. A one-week leaderboard asks something else again.

The example is frozen so the methodology page and portfolio dossiers share one evidence base. Current results continue in the Portfolio Lab: Live weekly series.

Frozen W31 evidence. Same hypothetical $10,000 start; common observation period January 3, 2005 to July 31, 2026; 2026-W31 snapshot; weekly receipt SHA-256.

• 100% QQQ — 20.2× ending multiple | 15.0% CAGR | −53.0% maximum drawdown | 0.28 Calmar

• 100% S&P 500 — 9.1× ending multiple | 10.8% CAGR | −54.7% maximum drawdown | 0.20 Calmar

• Stock-Gold 60/40 — 11.2× ending multiple | 11.9% CAGR | −35.1% maximum drawdown | 0.34 Calmar

• Classic 60/40 — 5.6× ending multiple | 8.3% CAGR | −28.4% maximum drawdown | 0.29 Calmar

• Harry Browne’s Permanent Portfolio — 4.5× ending multiple | 7.2% CAGR | −18.4% maximum drawdown | 0.39 Calmar

The benchmark’s maximum drawdown was −54.7%, slightly deeper than QQQ’s −53.0% in this window. That does not make QQQ safer: its 2000-02 crash is outside the common clock. It is a useful reminder that a benchmark, a growth extreme, and a full-history risk claim are three different questions.

The public audit trail

Every completed weekly run produces a dated receipt. Publication began with 2026-W31 and continues weekly. The public receipt is the SHA-256 hash of the exact bytes of that week’s latest.json. During the sealed period, the snapshot file remains private; the public record exposes the hash only. One hash proves little - the continuous series is the evidence. The goal is not to make the process look cryptographic. It is to make silent revision harder.

Changes fall into three layers:

Method changes the experiment - for example, a weight, vehicle, data treatment, rebalancing rule, or cost assumption. A method change requires a new version and a new frozen reference snapshot.

Framing changes the question asked of the same experiment - for example, adding a new diagnostic window, changing an axis from linear to logarithmic, or changing aggregation. A framing change must not shrink declared data coverage or hide any in-window sequence or extreme. It must be labeled without pretending the underlying portfolio changed.

Presentation changes how the same result is displayed - for example, improving a chart label. It must not alter the numbers.

Corrections are additive. The old receipt remains available, the correction states what changed, and a new artifact receives a new hash.

The sealed line: a public pre-registration

The Lab currently has one and only one sealed line outside the five public portfolios. It is an eight-asset, annually rebalanced experiment with a max-Calmar objective. Its optimization window is 2003-11-07 through 2022-12-31, with 2023-01-01 onward treated as out of sample. The specification is pre-registered under SHA-256.

Until its release condition is met: no peeking, no tweaking, no performance quotes. It does not enter the public leaderboard, and no sealed performance number appears here.

Any future sealed sample must publish its own specification hash before its shadow run begins. When this seal is lifted, a reader can hash the published specification and check the match.

What this method cannot tell you

The Lab can compare five models consistently. It cannot tell any individual reader which portfolio fits their goals, liabilities, taxes, account rules, time horizon, or ability to stay invested.

It cannot turn one historical window into a law of nature. The 2005-2026 record includes particular equity, gold, inflation, and rate regimes. Another era can reorder the results.

It cannot make historical maximum drawdown a safety boundary. Future losses can be deeper, recoveries can take longer, and real execution can differ from modeled execution.

And it cannot reduce portfolio choice to one number. Return measures the destination. Drawdown measures the deepest hole. Recovery time measures how long the old peak stayed out of reach. Volatility measures variation. Each leaves something out.

How the Lab answers the seven questions

The checklist is useful only when it reaches the actual experiment:

1. Window: January 1, 2005 inception; first common trading observation January 3, 2005; current frozen example through July 31, 2026.

2. Vehicle: investable ETF vehicles; GLD sets the common boundary and carries its expense ratio and tracking difference.

3. Return: daily adjusted close with distributions reinvested; below one year cumulative, three years and since inception annualized, with since-inception multiple also shown.

4. Cash flows: identical hypothetical $10,000 start and no later deposits or withdrawals; the models report time-weighted performance.

5. Execution: single-asset buy and hold; diversified lines rebalance annually at a 0.1% drift threshold with explicit modeled trading costs.

6. Verdict: Calmar is declared in advance and never re-chosen; Sharpe remains available with a constant 3% risk-free rate but is not the public verdict column.

7. Audit: exact weekly latest.json bytes are committed by SHA-256; method, framing, and presentation changes are labeled; corrections are additive.

If another backtest cannot answer these questions, its conclusion may still be useful. You just know where its claim becomes weaker.

That was my early relationship with investing: every choice felt wrong. I could read the backtests. I knew the annualized returns, the maximum drawdowns and the values at the end. I knew what had won and what had lost. It still did not tell me how to live through the middle.

That was the gap I had missed. A backtest gives you the destination. It does not make you walk the path — and the path is the part your nerve actually has to survive.

So I stopped looking only at where portfolios ended, and started watching how they moved: what fell first, what recovered, and how the same market could feel completely different depending on what you held. That didn’t make uncertainty go away. It did something smaller and more useful: it gave a vague fear a name, a size and a set of reference points.

Portfolio Lab: Live opens that process to you — not to sell you a portfolio, but to let you watch how portfolios behave before your own money ever has to find out. Five model portfolios. The same hypothetical $10,000 start. The same rules. A fixed scoreboard every Monday. No actual holdings, no changing the portfolio rules after seeing how they performed, and no promise that one of these portfolios will solve investing.

The point isn’t to crown a winner at the finish line. It’s to watch, week by week, what each portfolio asks of the person holding it.

All five portfolios below started with the same hypothetical $10,000 in January 2005. Two now sit at opposite ends of the scoreboard. 100% QQQ is worth $202,130 today; it suffered a −53.0% maximum drawdown along the way. The Permanent Portfolio is worth $45,003, with a maximum drawdown of −18.4%. The ending values alone cannot tell you which experience you could have lived through.

Most backtests end in the past. This one continues in public. Let’s see what the middle looks like from the inside.

Educational model tracking — not investment advice, no actual holdings.

The five lines

100% QQQ — QQQ 100%. The growth extreme: what maximum concentration in tech-heavy growth looks like, feels like, and costs.

100% S&P 500 — SPY 100%. The benchmark everything must beat.

Stock-Gold 60/40 — 48% SPY · 12% QQQ · 40% GLD. A case-study allocation from the Lab’s backtest research — not a textbook standard, and not a recommendation.

Classic 60/40 — 60% SPY · 40% TLT. The industry default: the allocation more of the world holds than any other. The control group.

Harry Browne’s Permanent Portfolio — 25% S&P 500 (SPY) · 25% long Treasuries (TLT) · 25% short Treasuries (SHY) · 25% gold (GLD). The textbook “all-weather” classic, published 1981.

Two of these five share a name. The Stock-Gold 60/40 and the Classic 60/40 differ in exactly one decision — what the defensive 40% is made of, gold or bonds — and that single decision is a running experiment inside the experiment. You’ll watch it play out every week.

Where the Stock-Gold 60/40 comes from. The Lab’s earlier backtest used XAUUSD spot gold over 1999–2025. In that study, this allocation returned 11.8% a year against the S&P 500’s 8.3% — while its worst drawdown was −33.9%, versus roughly −55% for the index. The live tracker below uses GLD and starts in 2005, so its figures are not directly comparable with that earlier study. Sixty percent stocks for growth, forty percent gold for the years stocks want to hurt you. That earlier result earned it a spot on this scoreboard — as a specimen to study, not a product to follow. This column is its first public appearance in English, and now it has to prove itself forward, in public, every week.

All five are ranked here by ending value. 100% QQQ leads at 15.0% a year, with one honesty note attached: QQQ’s worst disaster ever, the −83% dot-com crash of 2000–02, happened before this window begins. The Stock-Gold 60/40 made $112,472 (11.9% a year) with a worst fall of −35.1%. The S&P 500 made $91,122 (10.8% a year) and cost −54.7% in 2008–09 — the kind of drawdown that empties brokerage accounts through sheer panic. The Classic 60/40 made $56,344 (8.3% a year), cushioned to −28.4%. And the Permanent Portfolio closes the ranking at 7.2% a year — the least money, but the shallowest hole in the middle.

That’s the whole tension of portfolio construction in one chart — and the scoreboard below has a column that tries to measure it.

The scoreboard — Week 31, 2026

Read the shaded cells and you already know this column’s first lesson. QQQ owns year to date, the long-run return, and the ending multiple. The S&P 500 owns the week. Stock-Gold 60/40 leads the trailing one- and three-year windows. And the Permanent Portfolio owns the two columns nobody brags about: the shallowest maximum drawdown, and CALMAR, the verdict column.

Calmar is the honest referee of this table: annualized return divided by maximum drawdown — how much yearly growth each portfolio earned per unit of the worst pain it inflicted. Both ingredients are right there in the columns to its left; the only added step is the division. In the fixed display order, the readings are QQQ 0.28, S&P 500 0.20, Stock-Gold 60/40 0.34, Classic 60/40 0.29, and Permanent Portfolio 0.39. The 1981 Permanent Portfolio leads; the benchmark finishes last. The biggest pile of money and the most efficient pile of money belong to different owners.

The panel keeps the same shape every week — same five windows, same three structural columns, cumulative below one year, annualized above. A scoreboard that never changes shape can’t be used to flatter whoever happened to win this week. The format is the discipline.

The week under the microscope

Numbers summarize; days are what you actually live through. For this issue, both the scoreboard’s 1W column and the microscope use Friday, July 24’s close as their base, so the WEEK totals match the 1W column.

Notice what the color grid does to your stomach. By Wednesday’s close, QQQ was down 3.29% cumulatively from the prior Friday, while the Permanent Portfolio was down only 0.47% cumulatively. Then QQQ gained 3.30% in a single Thursday — one day nearly erased the previous three days’ decline — and every line finished the week above zero. The S&P 500 led at +1.09%; the Permanent Portfolio finished almost flat at +0.03%. If you only saw the weekly totals, the week looked calm. If you lived the days, it felt like a selloff followed by relief. Both are true; only one of them tempts you to do something unwise.

This week’s lesson: noise and signal disagree

Look at the scoreboard again. This week’s winner is the S&P 500. The trailing one- and three-year leader is Stock-Gold 60/40. The year-to-date and 21-year money winner is QQQ. The efficiency winner — return per unit of worst pain — is the Permanent Portfolio. Four different questions, four different champions, on the same data.

This is the lesson the Lab will repeat until it’s boring: short windows measure mood; long windows measure structure. Judge portfolios by weekly winners and you can end up switching week after week — collecting everyone’s drawdowns with no one’s compounding.

The sealed experiment

One more portfolio is already running in this lab — and you can’t see it yet.

It’s an 8-asset allocation the Lab optimized by machine — objective: maximize Calmar — on data from November 2003 through December 2022, and not touched since. Everything from January 2023 onward is out-of-sample: the model was frozen before any of it happened. Its full specification sits in a sealed document whose SHA-256 hash the Lab publishes today:

e3063e6874bd97767df5368a0ddd5846f0f6fed027e0faee1de96e78dec157de

When the Lab’s paid bench opens, the Lab will publish the document; you hash it and check the match. Until then, the seal cuts both ways: no peeking, no tweaking, no performance quotes — not one number, good or bad. It is the one and only sealed portfolio in the Lab, its weekly results are archived in version control as they happen, and when it’s revealed you’ll see its entire record — in-sample and out — including everything it got wrong. The Lab pre-registered this experiment the way clinical trials do, because a track record you assembled in the dark is only worth something if you can prove you couldn’t cheat.

The week ahead: what to watch

What to watch, not what to expect — this section lists scheduled facts and where they land on the bench. No forecasts, ever.

• August 4, 10:00 AM ET — June JOLTS. The labor-market release lands across the broad-equity legs and the Treasury legs in the Permanent Portfolio and Classic 60/40.

• August 7, 8:30 AM ET — July Employment Situation. The jobs report maps to every tracked equity leg and both Treasury-bearing portfolios. We will watch where the reaction appears, not forecast its direction.

What you’ll get every Monday

• Every Monday, before the bell: the five-line scoreboard, the week under the microscope, the 12-month chart, one lesson drawn from what actually moved — and what to watch in the week ahead.

• When the data earns it: occasional long-window or rebalancing specials. The fixed weekly issue remains the maintenance commitment.

• Someday: the seal comes off.

Extended methodology for this inaugural issue: the models start with a hypothetical $10,000 on 2005-01-01 — the first year-start after all component ETFs existed (GLD listed November 2004). Prices are total return, with dividends reinvested. Annual rebalancing uses a 0.1% drift threshold and includes an Interactive Brokers-style model for commission, slippage and market impact. Data are daily adjusted closes with dual-source checks. Returns below one year are cumulative; three years and since inception are annualized, and since inception also reports the cumulative multiple. Calmar equals annualized return divided by the absolute maximum drawdown, with no risk-free-rate assumption. This 2005–2026 window has been unusually kind to gold and unusually cruel to bonds, so the Stock-Gold versus Classic 60/40 comparison is window-dependent. Earlier long-horizon work may use XAUUSD spot gold for history; this tracker uses GLD, including its expense ratio and tracking difference.

Methodology: model portfolios, $10,000 hypothetical start on 2005-01-01, total-return (dividends reinvested), annual rebalancing, trading costs included. QQQ’s 2000–02 crash (−83%) predates this window. Full methodology for this inaugural issue: see the extended methodology above.

⚠️ Educational model tracking — not actual holdings, not investment advice. The Stock-Gold 60/40 is a case-study allocation from the Lab’s backtest research, not a recommendation. Past performance does not guarantee future results.
