What Is Delta? Delta is a risk metric that estimates the change in the price of a derivative, such as an options contract, given a $1 change in itsunderlying security. It is represented by the symbol Δ. The delta also tells options traders thehedging ratioto become delta neutral. A thi...
An economic derivative is an over-the-counter contract where the payout is based on the future value of an economic indicator.
