Pattern pages for GRMN
A direct answer for each pattern with enough detection history on GRMN to be worth its own page.
How has this setup performed historically?
| Window | Occurrences | Win rate vs SPY | Mean excess return |
|---|---|---|---|
| 5 days | 178 | 52% | -0.45% |
| 20 days | 151 | 50% | 0.05% |
| 60 days | 94 | 54% | -1.17% |
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.
