How has this setup performed historically?
| Window | Occurrences | Win rate vs SPY | Mean excess return |

Win rate = share of occurrences where the stock beat SPY over the window in the direction the signal predicted — for a bearish setup, a win means it underperformed. Measured since 2025-01-01 on our own detections, which puts the coin-flip line at 50%. Sample sizes are small; treat these as context, not as an edge.
