The VIX index is often used as a proxy define volatility for the current market volatility level. A measure of the degree to which a security rises or falls in price over a period of time.

That blue-chip stock is considered to have low volatility, while the tech stock has high volatility.

Beta And The Vix

Volatility is measured as the standard deviation of S&P500 one-day returns over a month’s period. The blue lines indicate linear regressions, resulting in the correlation coefficients r shown. Note that VIX has virtually the same predictive power as past volatility, insofar as the shown correlation coefficients are nearly identical.

Flat markets, or markets with low volatility, are associated with lower binary option prices. Volatility is a measure of how much the price or value of an asset will change during a period of time.
