What This Teaches
Which stock a quant system picks more often says more about price-action shape than about the business. SEDG kept printing clean golden-cross + breakout-volume setups (3 distinct clusters over 14 years); AMD printed them 1× in the same window. Same universe, same rules, different output, and that is exactly what a rules-based pipeline is supposed to produce.

Does this mean one stock is a buy and the other isn't?
No. Historical signal frequency and past returns are not buy recommendations. Our pipeline identifies entries that would have matched the template historically. Past performance does not guarantee future results. Use these pages as methodology research, not investment advice.
Where does the underlying data come from?
All entries on this page come from the R27 walk-forward validated backtest covering 2012–2025 (the 'seo_active' snapshot in our golden archive). Entry prices, returns, and SPY comparisons are computed from Stooq end-of-day OHLCV and frozen at snapshot time. See our methodology for details.
