'Volatility' is the measure of the state of instability.

★ Volatility (finance) frequently refers to the standard deviation of the change in value of a financial instrument with a specific time horizon. It is often used to quantify the risk of the instrument over that time period. Volatility is typically expressed in annualized terms, and it may either be an absolute number (''$5'') or a fraction of the initial value (''5%'').

★ Volatility (chemistry) is a measure of the speed at which a chemical element or chemical compound evaporates. Higher volatility indicates faster evaporation and a lower volatility means it will evaporate more slowly.
