Why it matters
Sharp jumps in volatility gauges signal heightened investor anxiety and rapid repricing of risk across equity markets. Historical patterns in the extraction offer a reference point for how markets have behaved after similar spikes.
The Cboe Volatility Index rose 11 points from 16.6 to 28.2, while the VXN climbed over 13 points to 38.3. In the historical sample of 19 instances since 1990, S&P 500 returns were positive in 68% of cases at three months and 79% at six months, though the one-month average return was negative 0.4%.
The players
Nasdaq 100 Index
A benchmark index tracking 100 of the largest non-financial companies listed on the Nasdaq stock exchange.
The details
The Cboe Volatility Index jumped more than 11 points on Thursday, November 5, 2026, and the Nasdaq 100 Index posted its steepest daily loss since March 2020. The volatility surge was broad across the Nasdaq-linked gauge, which also climbed sharply.
Timeline
November 5, 2026: VIX and Nasdaq volatility indices surged in a single session.
March 2020: The last time the Nasdaq 100 recorded a steeper daily loss.
April 11, 2025: The VXN last reached a level comparable to its current high.
February 24, 2020: A steep post-spike drop pulled down one-month average returns in the historical sample.
Market Dynamics
The current VIX spike falls into a pattern documented across 19 instances since 1990, when the index rose at least five points from below 20. In those cases, S&P 500 returns were positive in 68% of instances at three months and 79% at six months, though the one-month median return was just 2.1%.
For investors, a rapid rise in the VIX signals that options-based hedging costs are climbing and portfolio swings may widen in the near term. The historical sample suggests that positive three- and six-month S&P 500 returns were common after similar spikes, though one-month results were mixed.
The takeaway
Volatility spikes have historically been followed by mixed short-term returns and more favorable returns over longer horizons. Investors may find it useful to focus on time horizon rather than a single day's move when assessing risk.
