VIX Surges 74% to 27.62, Biggest Jump Since 2018 'Volmageddon'

Dec 18, 2024, 09:02 PM

On December 18, 2024, the CBOE Volatility Index (VIX), a key measure of market volatility, soared 73.87%, closing at 27.62—the highest single-day percentage increase since 'Volmageddon' on February 5, 2018, and surpassing any daily moves during the COVID-19 pandemic. The VIX reached an intraday high above 28, marking its highest level since August. This spike represents the second-largest one-day percentage gain in the VIX's history. The significant uptick in market volatility reflects heightened investor uncertainty, as the S&P 500 experienced substantial declines. The VIX's surge indicates a return of volatility to the markets.
