Key Observations
- High-beta / aggressive (β = 1.36): AMZN amplifies SPY — a 1% benchmark move maps to ~1.36%, cutting both ways.
- Benchmark explains 50% of AMZN's daily variance (R² = 0.50); a meaningful share is stock-specific, so treat beta as approximate.
- Forward-looking adjusted beta ≈ 1.24 (Blume: pulls the raw β one-third of the way toward the market's 1.0).
- α ≈ -7.6%/yr: after stripping out market exposure, AMZN underperformed SPY over the window (extrapolated from the daily intercept; not a forecast).
- Annualized volatility: AMZN 32.8% vs SPY 17.0% — 1.93× as volatile (more than the benchmark).
