— Beyond SPY — how this signal performs across markets —

Same fire days, different forward returns. Each row asks: when this signal fires, what does that asset do? The big number is the average return; underneath is how often the asset moved the same direction as the signal (50% would be a coin flip).

Regime matters

This indicator's strongest predictive edge sits in High VIX (stress): tuned σ = 2, window = 180d, horizon = 252d, hit-rate deviation from chance = 50.0pp.

Regime	σ	Window	Horizon	Hit dev
● Low VIX (calm)	2.50	240d	126d	38.0pp
● Normal VIX	2.50	90d	252d	40.9pp
● High VIX (stress)	2.00	180d	252d	50.0pp

Hit-rate deviation = |hit% − 50%| at the row's tuned horizon. Big deviation = strong directional edge in that regime. Regimes split by daily VIX terciles (low / normal / high) over a 1-year rolling window. Analyst + Trader subscribers will be able to filter the home grid and the fire-history bar chart by regime.

shaded cell = each row's strongest horizon (green = bullish forward return, red = bearish)“same direction” means the asset moved the same way the signal moved — opposite of a coin flip.
