What This Teaches
Stock screening is about frequency, not preference. MTCH was flagged 3× and CMCSA was flagged 1× because MTCH's weekly closes repeatedly matched the confluence we score for. That's why we publish the full record: the absence of a signal on a great company is as instructive as a signal on a mediocre one.

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.
