AAII Sentiment Survey

L2: Indicators · Signal 44 of 27

What This Signal Tells You

Imagine this weekly survey as a thermometer that measures the fever of the crowd rather than the actual health of the economy. When the needle swings too far toward extreme optimism, it often signals that too many people are already invested and have no one left to buy, while extreme pessimism suggests the selling pressure has largely been exhausted. This shift does not predict the exact date of a market turn, but it reveals when the balance of buyers and sellers is becoming dangerously fragile. For investors, watching this gauge helps identify moments when the crowd is most likely to act on emotion rather than logic, allowing for more disciplined positioning when sentiment reaches these extremes.

The Birth of Organized Retail Sentiment Measurement

Before 1987, understanding retail investor sentiment was an art form practiced through anecdotal observation and historical narrative. Professionals watched retail buying at market peaks and selling at troughs with bemused resignation, knowing that the crowd’s collective timing was reliably terrible. But quantifying this phenomenon in real-time was impossible—retail traders left no consolidated record of their positioning.

The American Association of Individual Investors (AAII) changed this by launching their weekly sentiment survey in 1987, during the crash recovery period. Each week, AAII members complete a survey indicating whether they’re bullish, bearish, or neutral on stock prices over the next 6 months. The results are tabulated and published as percentages of respondents in each category.

This seemingly simple metric—asking individuals whether they think stocks will go up or down—became one of the most reliable contrarian indicators in existence. Why? Because retail investors are demonstrably terrible at market timing, and this terrible timing is consistent enough to be predictive in reverse.

The Psychology of Retail Sentiment

Retail investors exhibit remarkably consistent behavioral patterns across market cycles:

• Recency Bias: Recent price action dominates forward-looking sentiment. Strong rallies create bullishness; recent declines create bearishness.

• Herd Behavior: As more investors turn bullish, it validates existing bullish views and creates social proof for converting hesitant investors.

• Overconfidence: After a period of profitable trading, retail investors become overconfident in their abilities, increasing bullishness.

• Fear Dominance: During declines, fear overwhelms rational analysis, creating bearish extremes that often mark bottoms.

• Extrapolation: Retail investors assume recent trends will continue unchanged—creating bull markets that are “sure things” and bear markets that are “doomed.”

Collectively, these patterns create a sentiment indicator that peaks at market tops and bottoms at market lows—making it a perfect contrarian tool when extreme readings are achieved.

The Mechanics of Sentiment Measurement

Understanding the Survey Structure

The AAII survey asks respondents a simple question: “6 months from now, do you think the S&P 500 will be higher, lower, or about the same?”

Respondents choose one of three categories:

• Bullish: Expect higher prices

• Neutral: Expect roughly flat prices

• Bearish: Expect lower prices

The survey is published weekly, typically on Thursday, providing a high-frequency sentiment snapshot. Sample sizes vary (typically 300-500 respondents) but are consistent over time, allowing for meaningful historical comparison.

Interpretation Framework

Bullish sentiment above 50%:

Retail investors are predominantly optimistic. This is a common Phase 1 reading, but when sustained for extended periods or reaching above 55%, it becomes a contrarian sell signal—excessive bullishness often precedes corrections.

Bullish 40-50%:

Moderate optimism. This is a neutral zone where no strong contrarian signal is present. Investors are neither excessively bullish nor bearish.

Bullish 30-40%:

Fear rising. Retail investors are split between hope and worry. This zone often appears during Phase 2 when positioning stress is mounting but hasn’t reached panic.

Bullish below 20%:

Extreme fear. Less than one-fifth of retail investors expect higher prices. This is the canonical contrarian buy signal—capitulation is complete, and value hunters typically dominate within days or weeks.

The Neutral % Component

An often-overlooked insight is that the percentage of neutral respondents tells a story parallel to bullish/bearish. During periods of high conviction (bull markets or bear markets), neutral readings shrink as investors are forced to pick a side. During periods of indecision or genuine equilibrium, neutral readings expand.

The highest neutral readings typically occur either:

• At market inflection points where genuine uncertainty exists

• During summer doldrums when low volatility reduces emotional intensity

Current Status — February 2026

AAII Bullish Percentage

47%

Current retail sentiment shows 47% bullish, which sits in the moderate optimism zone—above 40% but below 50%. This is not an extreme reading, but it’s elevated relative to historical averages (which center around 38-42%). The moderately elevated bullishness suggests retail investors maintain confidence but aren’t at peak euphoria levels.

Bullish

47%

Moderate optimism, above average but not extreme

Neutral

24%

Below-average indecision; most investors have taken sides

Bearish

29%

Elevated skepticism; growing segment expects declines

Recent Trajectory

The bullish percentage has evolved through recent months as follows:

• August 2024 (post-carry trade unwind): 35% bullish (fear spike, contrarian buy signal)

• October 2024: 48% bullish (recovery and renewed confidence)

• December 2024: 52% bullish (peak optimism for the year)

• February 2026: 47% bullish (modest pullback from peak)

The pattern is instructive: bullish sentiment peaked at 52% in December 2024, then has moderated to 47% in February. This pullback is subtle but meaningful—it suggests the enthusiasm that characterized end-of-year positioning is gradually eroding.

Key Observation: Bullishness Moderating from Peak

The decline from 52% (Dec 2024) to 47% (Feb 2026) represents a loss of confidence despite the S&P 500 hitting new all-time highs. This divergence—declining sentiment amid rising prices—is a classic warning signal of weakening conviction. Investors are being carried higher by momentum, but fewer believe the advance is sustainable.

Historically, when bullish sentiment peaks and then begins declining for 2+ consecutive weeks while prices remain near highs, the market is in late Phase 1 or early Phase 2 transition.

Phase Mapping: Retail Sentiment as Conviction Detector

Phase 1: Liquidity Illusion

Typical AAII Bullish: 45-55%, stable or rising

During Phase 1, retail sentiment gradually rises as the rally extends and becomes visible to the mass market. Early Phase 1 might see 40-45% bullishness as investors are cautiously optimistic. Mid Phase 1 sees 48-52% as confidence increases. Peak Phase 1 often coincides with 55%+ bullish readings as the crowd becomes convinced the market is a “sure thing.”

Current 47% suggests either mid-Phase 1 or the early stages of Phase 1 to Phase 2 transition.

Late Phase 1 → Phase 2 Transition

AAII Bullish: Peak to Decline (50%+ declining toward 40%)

The transition is signaled when bullish sentiment peaks (typically 50-55%) and begins declining while prices remain strong. This divergence indicates that even as the index hits new highs, retail investors are becoming skeptical. The psychology shifts from “this will go up forever” to “maybe I should take some profits.”

We’re in this exact zone: bullish peaked at 52% in December, now at 47%, while prices remain near all-time highs.

Phase 2: Crack Formation

AAII Bullish: 40-30%, declining trend

As positioning stress becomes visible and small corrections begin to accumulate, bullish sentiment deteriorates. Retail investors who rode the Phase 1 rally begin taking profits or hedging. Each minor decline triggers reconsiderations of bullish positioning. The psychological shift from “buy the dip” to “maybe the trend is changing” becomes visible in sentiment.

At 35-40% bullish, fear is clearly rising but hasn’t reached panic—this is the mid-Phase 2 zone.

Phase 3: Forced Liquidation

AAII Bullish: Below 30%, extremes approaching 15-20%

During panic liquidations, bullish sentiment collapses as fear dominates. The percentage of retail investors expecting higher prices falls below 25%, often reaching 15-20%. At these extremes, even investors who were bullish weeks earlier have capitulated. The emotional state of fear has overwhelmed rational analysis.

These extreme bearish readings (bullish <20%) are the most reliable contrarian signals—they mark periods when panic has exhausted itself and value hunting is about to begin.

Phase 3 → Phase 4 Transition

AAII Bullish: Stabilization and Rapid Reversal (bottoming near 15-20%, then rising)

The transition occurs when bullish sentiment, having fallen to 15-20%, suddenly stabilizes and begins rising as capitulation becomes complete. Within 2-3 weeks, sentiment can rise from 20% to 35% as early buyers begin finding value attractive. This rapid reversal often marks the true bottom of a crash.

Phase 4: Reset/Accumulation

AAII Bullish: 25-45%, gradually improving

Recovery is characterized by slowly improving sentiment as confidence is gradually restored. Rather than jumping from 20% directly back to 50%, sentiment grinds higher from 25% to 30% to 35% to 40% over months, reflecting cautious positioning. Conviction rebuilds slowly because memories of the recent crash remain vivid.

By the end of Phase 4, bullish sentiment has returned to 45-50% levels, setting the stage for potential Phase 1 transition if valuations are attractive, or for consolidation if valuations are extended.

The Contrarian Framework: Why Retail Sentiment Leads

The reason AAII sentiment is such a reliable contrarian indicator is that retail investors are:

• Late to trends: By the time retail investors adopt bullish positioning, institutional investors have often already moved ahead and are booking profits

• Reactive rather than proactive: Retail sentiment responds to recent price action rather than anticipating future moves

• Emotionally driven: Market sentiment more heavily weights recent gains/losses than fundamental analysis, creating overreaction

• Subject to herding: As more retail investors adopt a position, social proof encourages others to follow, creating extremes

Institutional investors have learned to fade retail positioning—when retail investors are maximally bullish, institutions reduce exposure. When retail investors are maximally bearish, institutions begin accumulating. This dynamic creates mean reversion: extremes in retail sentiment typically last 2-3 weeks before resolving.

Sentiment Divergences Worth Monitoring

While AAII sentiment is valuable on its own, it becomes more powerful when compared to complementary indicators:

• Price vs. Sentiment Divergence: When bullish sentiment declines while prices rise (as we’re currently seeing), the market is losing internal support. This typically precedes corrections within 2-4 weeks.

• AAII vs. Put/Call Ratio: When retail sentiment is bullish (50%+) but the Put/Call Ratio is elevated (>0.95), it suggests institutional investors are hedging against retail bullishness. This divergence often resolves with a correction.

• AAII vs. Market Breadth: When retail sentiment remains elevated but market breadth is deteriorating, it indicates retail investors are optimistic about a market that’s becoming narrower and more fragile.

• Duration of Extremes: Sentiment extremes lasting more than 2-3 consecutive weeks are more predictive than single-week spikes. Multi-week bullish extremes (50%+) preceded major corrections in 2000, 2008, and 2018.

Actionable Insights for February 2026

• Sentiment Confirmation Watch: Monitor whether bullish sentiment stabilizes at 47% or continues declining. Further decline to 45% would confirm deteriorating conviction amid price strength.

• Contrarian Positioning Opportunity: If bullish sentiment reaches 55%+ in coming weeks, that would be a strong contrarian signal for reducing risk. Current 47% is not yet at extreme levels requiring defensive action.

• Capitulation Watching: Watch for potential decline toward 20-25% bullish, which would indicate Phase 3 or Phase 4 entry points. When extreme bearishness emerges, it typically marks washout periods creating strong value.

• Neutral Percentage Tracking: Monitor the neutral percentage (currently 24%). If neutral rises toward 30%+, it could indicate genuine indecision about near-term direction—a potential transition signal.

• Weekly Reading Volatility: Track whether weekly readings are becoming more volatile (large swings week-to-week). Increasing volatility in sentiment often precedes increased volatility in price.

Historical Sentiment Extremes as Reference Points

For context on current readings, here are the most extreme AAII sentiment readings in the past 20 years:

• March 2009 (COVID crash bottom): 10% bullish (extreme capitulation, major buy signal)

• August 2011 (debt ceiling crisis): 12% bullish (another extreme bottom)

• February 2018 (vol spike): 15% bullish (brief but sharp panic)

• August 2024 (yen carry trade): 28% bullish (moderate fear, not capitulation)

• January 2018 (market peak): 58% bullish (near-extreme top)

• March 2017 (Trump rally): 61% bullish (extreme complacency)

Current 47% bullish is well above these panic extremes but below the complacency extremes. This confirms we’re in a “normal” mid-cycle range, not at phase transition extremes—yet.

Disclaimer: This analysis is for informational purposes. AAII sentiment is a contrarian indicator—it’s most reliable at extremes (below 20% or above 55%), not at moderate readings. Position sizing and risk management remain essential. Sentiment alone does not determine market direction; it must be integrated with structural and technical analysis.
