Alpha is a widely used metric to evaluate the performance of an investment in relation to the risk involved. This article will discuss, "What is Alpha Meaning? Difference Between Alpha and Beta". Let's get started.
What is Alpha Meaning?
Alpha is also known as the abnormal rate of return, excess return, or active return. It serves as an indicator of when an investment outperforms the market, an index, or a relevant benchmark during a specific time period. Essentially, it demonstrates when an investment beats the overall market.
Explanation of Alpha
Alpha can be positive or negative depending on the performance of the asset. For example, an Alpha of 5 signs that the asset has surpassed the market index or benchmark by 5%. Conversely, a negative Alpha value of -4 implies that the investment's performance is 4% worse than the benchmark. A negative Alpha doesn't imply a lack of return for investors; rather, it suggests that the return is lower than that of the benchmark.
For instance, let's say an investment generates a return of 12%, while the S&P 500 Index returns 7%. In this scenario, the Alpha is 5 (12 - 7), indicating that the investment has achieved a 5% excess return over the index's return.
Alpha is often used alongside other well-known performance assessment measures such as Beta, standard deviation, R-squared, and the Sharpe ratio. Investors typically prefer funds or portfolios with high and positive Alpha. Alpha is a commonly utilized measure for e valuating risk-adjusted performance, and a more detailed analysis can be conducted using a method called Jensen's Alpha. This approach incorporates the theoretical assumptions of the Capital Asset Pricing Model (CAPM) and a risk-adjusted factor.
Difference Between Alpha and Beta
Alpha and Beta are used together, but they assess different aspects. While Alpha measures excess return, Beta considers the volatility of a portfolio in comparison to the market. A value of zero for Alpha suggests that the portfolio's return is adequate given its le level of risk and that it closely tracks the benchmark or index return. On the other hand, a Beta value of 1 (baseline value) indicates that the portfolio moves in line with market fluctuations and is not exposed to higher or lower risk levels compared to the overall market.
