The screens

Legendary strategies, rebuilt from the books

Each screen is a faithful implementation of the guru's published criteria — with a real monthly backtest, not a marketing chart.

Full transparency

We don't say “trust us.” We show the math.

Every stock on every screen carries a full audit trail: the rule, the threshold, and the actual value from the SEC filing. Here is a screen, rule by rule.
