Glossary Definition

Most frequently refers to the standard deviation of the change in value of a financial instrument within a specific period. It is often used to quantify the risk of the instrument over that time period. Volatility is typically expressed in annualized terms as either an absolute number ($5) or a fraction of the initial value (5%). More broadly, volatility refers to the degree of (typically short-term) unpredictable change of a variable over time.
