What This Teaches
You can admire a stock and still never get a trade on it. AMD: 3 signal clusters across our backtest. RMBS: 1. 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.
