Volatility (redirected from Volatile (Economics))

Volatility

1. A statistical measure of the tendency of a market or security to rise or fall sharply within a period of time.

2. A variable in option pricing formulas that denotes the extent to which the return of the underlying asset will fluctuate between now and the expiration of the option.

Notes:

Volatility is typically calculated by using variance or annualized standard deviation of the price or return. A measure of the relative volatility of a stock to the market is its beta. A highly volatile market means that prices have huge swings in very short periods of time.
