August 18, 2017
On a historical basis, yesterday's drop isn't particularly significant. As Eddy Elfenbein at Crossing Wall Street noted, "Last year, the S&P 500 had 48 days in which it closed up or down by more than 1%. In 2015, there were 72. So far this year, there have been seven." In other words, yesterday's fall only feels so large because we've been locked in one of the lowest volatility environments ever for the past few months. Remarkably, the S&P 500 has yet to see a 3% peak-to-trough drawdown since election day, over nine months ago.
