Beta Coefficient ($\beta$)

Category: science

A measure of a stock’s volatility in relation to the overall market (usually the S&P 500).

Beta quantifies systematic risk. A Beta of 1.0 means the stock moves exactly in sync with the market. A Beta of 1.5 indicates the stock is 50% more volatile than the market (e.g., if the market drops 1%, this stock drops 1.5%). A Beta below 1.0 signals defensive, lower-volatility assets.

Common Examples

• We balanced the portfolio by adding low-Beta utility stocks to offset the high volatility of our tech-heavy growth positions.
• During market downturns, high-Beta stocks frequently suffer disproportionate losses, triggering our risk-management exit protocols.
