By midday Thursday the S&P 500 was down about 3.4%, the Nasdaq about 4.5%, and the VIX had spiked as much as 47% to touch 28. That came one day after the S&P 500 gained 1.6% on the midterm results. The reversal tells us more than the election did, because it changes the conditions a year-end advance would have to start from.
Sentiment Wasn’t Set Up a Week Ago
A week ago, Ned Davis Research made a point I agreed with: its daily trading sentiment composite was neutral, and the usual fuel for a midterm year-end rally wasn’t there. In 10 of the 11 midterm years since 1982, sentiment bottomed lower in the second half than it had this year. The September 18 low of 30.0 would have been the second-highest launch point for a midterm year-end advance since 1982, against a median low of 15.4. The conclusion wasn’t that stocks couldn’t rise. It was that if they did, they’d be doing it without the pessimism that has historically powered the move.
Now the setup is changing.
Fear Is Rising, and Price Is Confirming It
The latest AAII survey has 48.4% of individual investors bearish against 34.1% bullish. It closed Wednesday night, before Thursday’s selling, so it understates where the crowd is now.
That’s meaningful, but it isn’t capitulation. AAII bearishness reached 53.3% in September, so fear by itself isn’t new. What’s different is that pessimism is now being reinforced by price, by volatility, and by a sharp break in the market’s most important leadership.
Semiconductors and AI-related stocks are taking the brunt of it. The semiconductor index was down nearly 10% by midday, with some of the largest AI beneficiaries falling more, and the weakness has spread: every S&P 500 sector was lower. That matters because the AI capital-spending cycle has become one of the market’s dominant return drivers. When leadership is that narrow, a break in it carries more information than an ordinary pullback. If the rest of the market absorbs the damage and stronger areas take over, that’s rotation. If the weakness spreads into breadth, credit, volatility, and the longer-term trends, it’s a change of state.
Fear Alone Isn’t a Signal
Fear can improve the payoff, but it doesn’t tell us when the selling is finished. In a deteriorating regime, investors can get extremely bearish and prices can keep falling anyway, and the midterm record shows both outcomes. In 2018, sentiment turned pessimistic in October, the market bounced through the day after the election, and then the selling resumed, taking the S&P 500 down 19.8% from its September high to the December 24 low. In 2022, sentiment troughed seven trading days before the market did, and the S&P 500 gained 14.1% by the end of November. Same pessimism, opposite outcomes. The difference was what the market did next.
So the edge isn’t in the sentiment reading. It’s in combining it with evidence that downside pressure is exhausting.
What a Better Starting Point Looks Like
What we want to see is straightforward: selling pressure exhausts, volatility stops expanding, breadth stabilizes, and price starts confirming that buyers are taking control again. If that happens while pessimism is still elevated, the setup becomes far more asymmetric than it was when stocks were higher and investors were comfortable. We’d have lower prices, worse expectations, more defensive positioning, and evidence that the market can absorb bad news. That’s a much better starting point for an advance.
The opposite matters just as much. If volatility keeps expanding, leadership keeps breaking, breadth deteriorates, and the major trends fail, pessimism isn’t a reason to buy. It’s confirmation that the market’s state has changed, and the right response is less exposure, not more.
Contrarian Isn’t the Same as an Edge
Buying because everyone is bearish is an opinion. Waiting for pessimism to reach an extreme while the market starts proving the selling is exhausted gives us information about both sides of the payoff: how much is left to lose, and whether the upside has started to assert itself. That’s the difference between being contrarian and having an edge.
A week ago, sentiment wasn’t giving us much. Today the risk/reward is changing because prices are falling and fear is rising, and the two are finally moving together. We’re not looking for a reason to predict a year-end advance. We’re looking for the conditions that could make one worth participating in.
A worse market may be exactly what produces them.
