Expected Value

Definition of 'Expected Value'


Anticipated value for a given investment. In statistics and probability analysis, expected value is calculated by multiplying each of the possible outcomes by the likelihood that each outcome will occur, and summing all of those values. By calculating expected values, investors can choose the scenario that is most likely to give them their desired outcome.
