Beta Calculator
Beta measures a stock's historical volatility relative to a benchmark index (like the S&P 500). A Beta of 1.0 means the stock moves with the market; 2.0 means it is twice as volatile.
Warning: Beta is a backward-looking metric. AI-managed funds (see our analysis on AI ETFs) often accidentally create portfolios that are simply high-beta factor bets disguised as algorithmic alpha.
Always combine Beta analysis with absolute downside metrics like Value at Risk (VaR).
