The sentiment in the US stock market appears buoyant following the suspension of tariffs on Liberation Day by Trump. This optimism is reflected in the AAII survey, which shows a rise in bullish sentiment to 45% from 35.1%.
This increase suggests confidence as the market reaches new highs nearly daily. However, the current level has not yet reached the frothy benchmark of over 50%. In mid-July last year, the bullish sentiment peaked at 52.7% before the S&P 500 experienced a 9% drop due to economic concerns.
The Role Of The Federal Reserve
Following this decline, the Federal Reserve intervened, leading to a recovery in stock prices. As such, if bullish sentiment surpasses 52%, caution is advised. The possibility remains for the S&P 500 to reach milestones of 6500 or even 7000.
The recent uptick in investor confidence, as shown in the AAII retail sentiment survey, provides an early indicator rather than a guarantee. When optimism among individual investors climbs substantially, history shows that the market has often responded with setbacks, particularly if economic fundamentals don’t support that enthusiasm. Last year’s sharp pullback after the sentiment crossed 50% serves as a clear reminder, and with the index once again knocking on psychological thresholds, attention to positioning becomes more urgent than usual.
Sentiment rising from 35.1% to 45% suggests we are entering a zone where expectations may become disconnected from economic or company earnings growth. The proximity to the 50% mark should raise questions for anyone using leverage or holding closely correlated contracts. This sort of optimism often leads to stretched valuations, and that naturally increases exposure to unwinding pressure once even minor macro disappointments appear.
Tariff developments clearly provided a catalyst this time. When Trump suspended those tariffs, equity markets responded positively, bringing action back to new highs. Yet, we’ve seen before how quickly the narrative tilts. Just a few weeks of softer labour reports or weaker corporate results, and this newfound confidence can start reversing.
If momentum persists and the S&P 500 edges closer to 6500 or even 7000—levels mentioned in speculative circles—it will likely result in increased volatility in derivative pricing. Premiums could inflate due to higher demand for both calls and downside insurance. Already, traders might have noticed spreads widening slightly at the longer end of the curve. That alone tells us sentiment is not the only thing heating up.
Monitoring Market Volatility
When sentiment readings approach 52%, we do not wait for confirmation. We prepare. Risk premiums often lag changes in outlook, so by the time volatility spikes, prices have already shifted. What we must do is monitor implied volatility levels, especially across shorter-dated options, to identify where mispricings may emerge. Selling into inflated premiums can be profitable, but only when backed by hedges. This is no time to be exposed without adequate protection from market surprises.
Some traders continue to buy upside exposure, particularly in single names with aggressive earnings forecasts. We are avoiding crowded trades with unrealistic upside baked in. Put-call ratios on some of the leading tech names suggest a one-sided trade. When ratios fall beneath a certain threshold—below 0.6, say—it becomes obvious where the herd is.
Instead, we’ve found better opportunities in skewed structures—where upside is financed by cautious downside views—or calendar spreads on sectors tied to rate sensitivity. With the central bank now weighing its next steps post-recovery, even a dovish signal could lead to sharp reactions in fixed income futures. Watch STIRs for early clues. Changes in overnight expectations tend to ripple through quickly, cascading into equity and FX-linked trades.
Bullish positioning is not inherently wrong, but chasing an already stretched rally without recognising when crowding reaches late-phase levels has rarely been profitable. It’s tempting to stay in the flow while the rising tide lifts everything. But it is precisely at a time like this—just before speculative ceiling levels—that diligence pays the most.
This is not about calling a top. It is about managing exposure responsibly. When thinner summer volumes meet frothy public sentiment, liquidity can vanish in hours. That is when overstretched option sellers or turbocharged long positions face the sharpest drawdowns.
Keep your charts. Keep your quant models. But more than anything, keep your awareness of what happened the last time sentiment crossed the 52% line. We aren’t there yet, but the pattern is predictable enough that waiting for full confirmation has often meant reacting too late.
