What This Teaches
You can admire a stock and still never get a trade on it. ANET: 6 signal clusters across our backtest. SNPS: 2. The screener doesn't know which is the 'better' company; it just rewards whichever chart keeps producing the entries our weights favour. Publishing both the hits and the misses is how we keep the methodology honest.

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 R30 walk-forward validated backtest covering 2012-2025 (the 'seo_active' snapshot in our golden archive). Entry prices, returns, and SPY comparisons are computed from end-of-day OHLCV and frozen at snapshot time. See our methodology for details.
