Symbol-scoped β / α / R² vs benchmark.
Beta is window-dependent. Short-window beta captures recent regime; long-window beta smooths through cycles. Compare across windows: 60d > 252d = beta is rising (the stock is getting more market-sensitive).
Alpha = excess return after stripping out beta-explained moves. R² = how much of the stock's variance is explained by the benchmark. R² > 0.7 = beta is meaningful; < 0.3 = beta is a poor fit, idiosyncratic risk dominates.
Lower strip plots beta as a time series. Trending up = beta rotation (e.g. defensive name turning cyclical). Spike + revert = event-driven outlier in the regression window.
Benchmark defaults to SPY (S&P 500 ETF). Click to swap to IWM (Russell 2000), QQQ (Nasdaq-100), or sector ETFs. Different benchmarks give different betas — high tech-name vs QQQ < 1.0 can be > 1.5 vs SPY.
