beta
investment risk
Quick Summary
Beta is a financial metric that measures a stock or fund's volatility in relation to a broader market benchmark, typically the S&P 500. It quantifies market risk, also known as volatility, which represents uncertainty for investors.12
Interpreting Beta Values:
- Beta of 1.0: The asset's movement is in sync with the market benchmark.12
- Beta > 1.0: The asset is more volatile than the market. For example, a beta of 1.5 suggests a 1.5% move for every 1% move in the benchmark.12
- Beta < 1.0: The asset is less volatile than the market. A beta of 0.75 indicates a 0.75% move for every 1% move in the benchmark.12
- Negative Beta: The asset moves inversely to the market.12
Beta is a key component of the Capital Asset Pricing Model (CAPM) and can be used to forecast returns, manage portfolios during market trends, and aid in diversification. However, beta is backward-looking and can change over time, so it's best considered alongside other metrics.12
