What is a Support Break?
Support and resistance levels are horizontal lines on a chart that represent price levels where the market has previously struggled to move beyond. Support is a level at which buying interest is strong enough to prevent the price from falling further, while resistance is a level where selling pressure is strong enough to prevent the price from rising further. A breakout above a resistance level or below a support level can signal a significant shift in market sentiment. However, false breakouts can occur, so it's important to confirm the breakout with additional indicators or price action.
How has this setup performed historically?
| Window | Occurrences | Win rate vs SPY | Mean excess return |
|---|---|---|---|
| 5 days | 40 | 57% | 0.02% |
| 20 days | 37 | 46% | -1.93% |
| 60 days | 25 | 40% | -7.21% |
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.
