Key Observations
- GRMC moves inversely to SPY (β = -89.09): a 1% rise in the benchmark is associated with a ~89.09% fall, so it has historically acted as a hedge.
- Benchmark explains only 3% of GRMC's daily variance (R² = 0.03): SPY is a poor fit — beta is statistically weak and driven mostly by idiosyncratic moves.
- Forward-looking adjusted beta ≈ -59.06 (Blume: pulls the raw β one-third of the way toward the market's 1.0).
- α ≈ +132,722.6%/yr: after stripping out market exposure, GRMC outperformed SPY over the window (extrapolated from the daily intercept; not a forecast).
- Annualized volatility: GRMC 17,783.5% vs SPY 32.8% — 541.89× as volatile (more than the benchmark).
