What This Teaches
Which stock a quant system picks more often says more about price-action shape than about the business. ORLY kept printing clean SMA20/50 crossover + breakout-volume setups (32 distinct clusters over 14 years); CMCSA printed them 26× in the same window. Same universe, same rules, different output, and that is exactly what a rules-based pipeline is supposed to produce.
