How unpredictable is the U.S. stock market right now? It’s a place where the Standard & Poor’s 500 Index, a collection of the world’s most stable companies, is suddenly bouncing around more violently than small caps.

Since stocks started selling off last month, implied volatility, the options-derived measure of turbulence codified in the VIX, has repeatedly risen above a similar measure tied to the Russell 2000 Index of smaller stocks. It’s closed that way six times since Aug. 24, compared with twice in the prior 11 years.
