Knowledge is AlphaAlpha is important in that it is the measure of a portfolio’s return that is in excess of the market return after both are adjusted for risk. If a fund returns more than what one might expect given its Beta (i.e., a measure of how much one can expect a fund's returns to move up or down given a gain or loss of its benchmark), it exhibits positive Alpha. If a fund returns less than its Beta predicts, it shows negative Alpha. |
