A second part of the context for the drop is that volatility had become unusually compressed in July. We have shown this chart several times in the past: when the SPX Bollinger bands become very tight (lower panel), an expansion in volatility is typically close behind (middle panel). The recent range compression was the most extreme since January 2007. A small warning is that SPX fell 7% in February 2007.
