What This Teaches
Signal frequency is not opinion; it's the pipeline firing or not firing against the same rules. Over the 2012–2025 window, GOOGL triggered entries 2× versus 2× for TTD. The lesson here isn't that one company is better than the other; it's that the template is tuned for a specific kind of setup and this pair shows which stock's price behaviour kept offering that setup.

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.
