Say hello to the largest 2-day VIX rise in history...
VIX (Daily)
A 188% rise from Thursday's close. This VIX panic comes after what can likely be called the longest period of low volatility in market history; including the longest streak ever without consecutive .50% single-day losses in the S&P 500.
An interesting stat via SentimenTrader after the close: "Stocks have never declined between 1-6 months after the VIX has jumped more than 50% in one day." Granted, there is an extremely small sample size of +50% VIX days.
