Not that anyone is counting, but market volatility today is comparable numerically to market volatility in the depths of the global financial crisis of 2007-2009. Today, the CBOE’s implied volatility index (ticker symbol VIX) closed at 54.46. Putting this into a historical perspective, this level is at the 99.43rd percentile for all 7,557 daily observations on VIX recorded daily during the 30-year period spanning 1/2/1990 – 12/27/2019. The last time that VIX closed at this high of a level occurred on November 5, 2008, when it closed at 54.56.
