VIX Spikes 70% in One Day: Wall Street's Third-Biggest Fear Jump Since 1990

The VIX jumped 69.66% in a single day to 28.18 — its third-largest one-day percentage gain since 1990. Wall Street's fear gauge exploded on Thursday, November 5, as the AI trade unwound, the Nasdaq fell into correction, and investors who had been calm a day earlier rushed for protection all at once.

What happened to the VIX?

The Cboe Volatility Index, known as the VIX, closed at 28.18 on Thursday, up from 16.61 on Wednesday. That is a rise of 11.57 points in one session. Only two one-day percentage gains since 1990 were larger: February 5, 2018, when the VIX rose 117.48%, and December 18, 2024, when it rose 74.04%, according to a Benzinga study reported by TradingView.

CNN put the move at roughly 70%, calling it the biggest one-day surge in almost two years and the highest level in seven months. Inc. noted the jump was bigger than any single session in March 2020, when the pandemic shut down the global economy — the largest day then was 42.9%.

Why did fear spike so fast?

The trigger was a brutal sell-off in AI and chip stocks. The Nasdaq Composite fell 5.52% on Thursday, its worst day since April 2025, and closed more than 10% below its October 6 record high — in correction territory. The S&P 500 fell 4.36% to 7,353.73, and about $2.5 trillion in market value was wiped out in the rout, CNN reported.

Investors were reacting to Democratic midterm gains and fears that new state rules could slow the data-center buildout behind AI. Texas, a hub for planned data centers, was at the centre of that concern. Chipmakers and the companies supplying the buildout were hit hardest, and all 11 sectors of the S&P 500 closed lower.

The low starting point amplified the move. The VIX had closed Wednesday at just 16.61, near its 50-day average of about 16.7. When volatility is cheap, investors carry less protection — a sudden shock sends them buying it at once.

What does the VIX actually measure?

The VIX measures how much movement traders expect in the S&P 500 over the next 30 days, based on the prices of S&P 500 index options. It does not measure what has already happened, and it is not a forecast of direction. A higher VIX means options traders are paying more for protection against big swings, up or down.

At 16.61, the market priced roughly 1% daily moves. At 28.18, that expected range had grown by about 70% — calm turned to hedging in one afternoon.

Why is this blowing up now?

Because a 50%-plus VIX day is rare. The Benzinga study found the VIX has jumped 50% or more in a single session just 10 times since 1990. That rarity is why traders are sharing the chart this weekend, and why the history matters more than the headline number alone.

In nine of those 10 cases, the S&P 500 was higher one month later. The average one-month gain after a spike was 2.56%, with a 90% win rate — more than three times the 0.81% average for all one-month periods. Over three months the average gain was 5.55%, and over six months it was 9.04%.

What happened next on Friday?

Friday brought a partial rebound. After the October jobs report showed 165,000 new jobs and unemployment at 4.1%, chip stocks bounced and the VIX eased 5.2% to 26.71, Benzinga reported — still well above Wednesday's close.

What is next?

History favours a bounce over the next month, but it warns against expecting a smooth one. On average after these spikes, the S&P 500 still fell 5.71% from its high at some point in the following month. The worst one-month case followed the July 1990 spike, just before Iraq invaded Kuwait, when the index was down 13.58% a month later. The November 2021 spike was followed by a 13.73% fall over the next year as the Federal Reserve began raising rates.

Ed Yardeni of Yardeni Research called the sell-off overdone and kept a 7,900 year-end S&P 500 target, while others warned the 2018 midterm volatility pattern could repeat. Either way, volatility tends to cluster, so more choppy sessions are likely. This report describes what happened and what history shows; it is not a recommendation to buy, sell or hold any security.
