Volatility

In finance, volatility is a measure the dispersion of returns of a security or portfolio. It can be calculated as the variance or standard deviation of returns over a given period of time. Returns can be measured over a daily, weekly or monthly period. Volatility is considered a good, but imperfect proxy for risk. Commonly, the higher the volatility, the riskier the security.
