Yes it is. Also the largest absolute 1-day percentage change regardless of direction. 1 standard deviation of daily price change since I began tracking it is 2.45% so if you accept gaussian distribution of equity prices (I do not), the odds of a move this size is about 1 in 333.

I'm curious, is this the biggest single down day you've recorded since tracking the index?
