A Chart Of Recent S&P500 Price Volatility

The following chart depicts the S&P500 in 10 minute intervals from July 20 through yesterday’s close.  As such, it encompasses the progression of the stock market since its July 25 daily high of 1344.32:

The blue line is a 50-period moving average.

What I find notable is the frequency and extent of the price volatility.  As one can see, there have been several episodes of advances and declines of roughly 80-100+ points in rapid fashion – some even happening over the course of a few days.

While there are various ways to interpret such volatility, my overall belief is that such is (yet another) cautionary sign.
