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).

Each fire in history — when the signal popped, what SPY did next

Each bar is one historical fire — the indicator's value moved 2.5+ standard deviations from its rolling 180 trading-day mean (~9 months), or for monotonic “days since” indicators, crossed an 80th/90th/95th/99th percentile. Bar height = SPY's forward return at the selected horizon, signed by signal direction. Green above zero means the market moved with the signal; red below zero means it moved against.
