Stock Market Volatility

You don’t need us to tell you that the market has been volatile, but I thought these statistics were interesting at the very least:

Year to date through Sept. 15, the average daily change in the Dow Jones Industrial Average (DJIA) was 122 points. Since that time, the average daily change is 348 points per day.

Prior to Sept 15, there were no moves greater than 500 points, but since then we have had six days where the DJIA moved in excess of 500 points. We have also had 10 trading days with intra-day movements of more than 750 points.
This graphic from NYTimes.com last week gives some perspective on the scale of stock market volatility.
