Volatility is a statistical measure of a security's or market index's return dispersion. The more the volatility, the riskier the security is in most circumstances. A "volatile" market, for example, is one in which the stock market rises and falls by more than 1% over a long time.
There are several ways to measure volatility, including beta coefficients, option pricing models, and standard deviations of returns.
