In November 2025, the American Association of Individual Investors asked its members the same question it has asked every month since late 1987: what percentage of your portfolio is in stocks and stock funds, what percentage is in bonds and bond funds, and what percentage is in cash. The answer came back at 71.17% in stocks. Cash sat at 14.83%. The series has stayed elevated since: 68.5% in April 2026, 71.0% in June 2026, 71.05% in August 2026 and 71.8% in September 2026, with cash down to 13.3% in September 2026.
Those two numbers are the story. Over roughly the past thirty years, AAII members have averaged about 61.5% in stocks, 16% in bonds, and 22.5% in cash. So the November reading had individual investors roughly ten percentage points heavier in equities than their own long-run habit, and holding barely two thirds of their usual cash buffer. AAII's own release for the month was titled "November AAII Asset Allocation Survey: Bond Allocations Decrease," and the mechanics were straightforward: money moved out of bonds, and both stocks and cash picked it up.
The reason this made headlines is historical. Going back through the monthly series, only a handful of readings sit above 71.17%. One is December 2017, at 72.0%, and one is September 2026, at 71.8%. The others belong to the dot-com era, including a 74.0% reading in July 2000 and a peak of roughly 77% in March 2000, at the top of the technology bubble. Outside that bubble, there is almost nothing in a quarter century of data that looks like this.
In this article we explore what the AAII Asset Allocation Survey actually measures, how it differs from the better-known weekly sentiment poll, why extreme retail bullishness has long been treated as a contrarian warning sign, what the historical comparisons to 2000 and 2017 genuinely support, and where the contrarian story gets weaker than its popularity suggests.
What the Survey Actually Measures
The AAII Asset Allocation Survey is a self-reported portfolio census. Members are asked to split their holdings three ways, and the published figure is the average across respondents. It has run monthly since November 1987, originally collected by postcard and now by online voting, and results are published on the first day of each month reflecting the prior month's allocations.
The distinction that matters is between sentiment and allocation. Sentiment is an opinion. Allocation is a position. Someone can tell a pollster they feel nervous about the market while still holding a portfolio that is three quarters equities, and the portfolio is the thing that determines what happens to their wealth. The allocation survey is therefore closer to a measure of exposure than of mood, which is part of why strategists pay attention to it.
It is still a survey, though, not a custody record. Nobody audits the responses. AAII members are a self-selected group of engaged individual investors, people interested enough in markets to join an investor education organisation and answer a monthly questionnaire. They are not a random sample of American households, and the survey does not measure dollars, so a member with a large portfolio and a member with a small one count the same.
How November 2025 Compares With History
The useful way to read the number is as a percentile, not an absolute.
- The long-run average equity allocation is about 61.5%.
- From April 2022 through 2024 and 2025, monthly readings repeatedly ran in the 68% to 70% range, already above average, before rising above 71% in November 2025.
- December 2017 produced 72.0%, which rose 3.4 percentage points in a single month and was described at the time as the largest equity allocation since July 2000.
- July 2000 recorded 74.0%, and March 2000, the dot-com peak, recorded roughly 77%.
So the November 2025 figure is not an all-time record. It is, however, higher than every reading in the past quarter century except December 2017, September 2026, and the bubble-era extremes. That is a meaningful distinction. Readings in the low seventies are rare, and the company they keep is uncomfortable.
It is also worth noting what did not happen. Equity allocation did not spike in a single month the way it did in December 2017. It drifted up over years, from the high sixties into the low seventies. A grind is psychologically different from a lurch. It suggests accumulation rather than a sudden rush, which may matter for how it unwinds.
The Cash Number Is the Quieter Signal
Cash allocation at 14.83% against a long-term average of roughly 22.5% deserves as much attention as the equity figure.
Cash in a portfolio does two jobs. It cushions losses, because it does not fall when stocks do. And it is dry powder, the money available to buy when prices drop. When households collectively hold less of it than usual, both functions weaken at once. Drawdowns bite harder, and there is less sidelined money ready to step in and absorb selling.
There is a second-order effect. An investor with a thin cash buffer who needs money for a real-world expense during a market decline has to sell securities to raise it. That turns a personal cash-flow event into forced selling, and forced selling at depressed prices is how paper losses become permanent ones. Low aggregate cash makes a market marginally more fragile, not because of any prediction about direction, but because the system has less slack.
Why This Is Treated as a Contrarian Indicator
A contrarian indicator is a reading that is interpreted as a signal to do the opposite of what it describes. When a gauge of crowd positioning hits an extreme, the contrarian argument says the extreme itself is the problem.
The logic has two strands.
The first is mechanical. If individual investors have already moved most of their money into stocks, the marginal buyer is largely spent. Prices rise when money comes in. Money that is already in cannot come in again. A 71% equity allocation says a lot of the buying that was going to happen has happened.
The second is behavioural. Confidence is highest after prices have risen, because rising prices are what create confidence. That makes bullish extremes a lagging record of good returns rather than a forecast of future ones, and it means the crowd is at its most exposed precisely when the cushion of cash is thinnest.
AAII itself frames its sentiment work in contrarian terms, noting that extreme bullish or bearish readings have historically been followed by moves in the opposite direction.
The Weekly Survey Is a Different Instrument
The AAII poll most often quoted in financial media is not the allocation survey but the weekly AAII Investor Sentiment Survey, which asks members a single question: will the stock market be up, flat, or down over the next six months. Over the life of that survey, responses have averaged 37.5% bullish, 31.0% neutral, and 31.5% bearish.
The two should not be conflated. The weekly survey captures mood and can swing violently week to week. The monthly allocation survey captures positioning and moves slowly. Mood can reverse in a fortnight. Portfolios usually do not.
Both differ again from professional sentiment gauges such as the Investors Intelligence Advisors Sentiment Report, which has polled investment newsletter editors since 1963. Professional-sentiment measures tend to follow trends rather than anticipate reversals, because advisers write to an audience and an audience rewards confirmation. The retail base of the AAII surveys is what gives them their distinct, and distinctly contrarian, reputation.
Where the Contrarian Story Weakens
The contrarian framing is widely repeated, and it is not unchallenged by the evidence.
Academic work by Kenneth Washer, Robert Johnson, and Gerald Jensen examined the allocation survey directly. They found that changes in AAII members' allocations are positively related to the previous month's stock return, which is the performance-chasing behaviour the contrarian story assumes. But they also found that the survey's allocations outperformed common rule-based active and passive strategies. In other words, the members chased returns, and chasing returns worked. A crowd that leans into equities during long bull markets will, over long bull markets, do well.
There is also the problem of timing. The December 2017 reading of 72.0% was followed by a volatile 2018, but equity markets over the following years went considerably higher. Extreme readings have historically tended to precede below-average returns, but "below average over some unspecified horizon" is not a trading signal, and an indicator that can be early by years is not one a portfolio can be built around alone.
Finally, the "second-highest since 2000" framing is an inference from comparing historical monthly data rather than a claim AAII itself has published. The counter-argument, that a high allocation simply reflects a genuinely strong and still-rising market, deserves airing precisely because it has not been formally rebutted.
How to Use a Reading Like This
A positioning extreme is a statement about vulnerability, not about direction. It says the crowd has little room left to add and little cash left to cushion. It does not say when, or whether, that matters.
The practical question an individual can answer is simpler than the market-timing one: how does a personal allocation compare with a personal plan. If an equity weight has drifted from a target into something materially higher because stocks rose rather than because of a deliberate decision, that is a rebalancing question, and it is answerable without any forecast at all.
Key Takeaways for Investors
- The AAII Asset Allocation Survey showed individual investors at 71.17% in stocks and stock funds in November 2025, against a long-run average of about 61.5%.
- Cash stood at 14.83% versus a long-term average of roughly 22.5%, meaning thinner shock absorbers and less sidelined buying power.
- Only December 2017 at 72.0%, September 2026 at 71.8%, and the dot-com era, including 74.0% in July 2000 and roughly 77% in March 2000, sit higher in the modern record.
- The reading built gradually from the high sixties over several years rather than spiking, unlike the 3.4 point jump into December 2017.
- The monthly allocation survey measures positioning; the separate weekly AAII Sentiment Survey measures opinion. They are different signals and should not be used interchangeably.
- Research by Washer, Johnson, and Jensen found AAII members chase prior-month returns yet still outperformed common rule-based strategies, which complicates a purely contrarian reading.
- Extreme readings are statements about fragility and limited remaining buying capacity, not timing signals.
Conclusion
The value of a survey like this is not that it predicts anything. It is that it makes visible something normally hidden: how much risk the retail crowd has quietly accumulated while nobody was counting. Over several years, individual investors moved from a historically normal equity weight to one matched only by the final stretch of the dot-com bubble and a single month in 2017, and they did it without any single dramatic decision.
That is how concentration usually happens. Not through a plunge into the market, but through the absence of a decision to trim. The number does not tell anyone what the market will do next. It tells them how much of their outcome now depends on the answer.
