volatility

Statistics

An alternative name for standard deviation which is used in the context of finance.

Chemical Engineering

The tendency and measure of the ability of a liquid to go into the vapour phase expressed as the ratio of the mole fraction in the gas phase (y_A) to that in the liquid phase (x_A):
$K_{A} \frac{y_{A}}{x_{A}}$

The relative volatility is a comparison of the lightness of two components and can be found by taking a ratio of the vapour phases of the two components.

Economics

Same as dispersion. In finance, volatility usually refers to the rate at which a financial variable, such as stock price, moves up or down over time. Volatility is measured by the standard deviation or, sometimes, by the variance. The (absolute) empirical volatility of a stock price is usually calculated as the annualized standard deviation of daily change in price. A measure of the volatility of a stock relative to the market is its beta coefficient.
