Evidence-backed screens

Every screen on this page is a finding that survived testing, applied to the companies we cover today. There is no screen here that was invented first and justified afterwards: if a measure did not hold up across every period we tested, it does not get a screen, however sensible it sounds.

A screen is a starting point for research, not a recommendation. Historical frequencies describe a group of companies over a period; they say nothing about which individual company will do what next.
