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.

Each bar = one fire day (|z|≥2.5 from 180-day rolling baseline). Bar height = SPY return over the the next year, signed by signal direction. Dashed line = average across fires.
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.
