Definition
Alpha (α) is a financial term that quantifies the performance of an investment relative to a benchmark index, adjusted for risk. It essentially tells investors whether their investment strategies are outperforming or underperforming the market. Investment strategies that achieve a positive alpha have “beaten the market,” while those with negative alpha have lagged behind.
