What volatility expansions tell us about expectations for stock market trends

A volatility expansion implies that stock prices are expected to spread out more, as measured by the (VIX) CBOE Volatility Index. Currently, it’s at 28, which would imply a 28% expected volatility over the next 30 days, except it tends to be priced at a premium above realized vol.

Then, historical volatility, or realized actual volatility,  such as the 30-day rolling volatility, suggests prices are indeed spreading out. So, expect a wider range up AND down in volatility expansions. In the chart below, 30 Day Rolling Volatility = Standard Deviation of the last 30 percentage changes in Total Return Price * Square-root of 252. At this point, it’s at 17.71% when applied to the S&P 500 stock index data.

A volatility expansion like this suggests in the near term stock prices are expected to spread out more, but up and down.

We are seeing a broad range of prices today, form up 1.4% to down -0.60%, as seen below.
