Definition of Delta


Delta is used with respect to options: The rate of change of a financial derivative's price with respect to changes in the price of the underlying asset. Formally this is a partial derivative.

A derivative is perfectly delta-hedged if it is in a portfolio with a delta of zero. Financial firms make some effort to construct delta-hedged portfolios.
