Intersection of 13F position increases and Form 4 open-market buys. Different lags apply to each source; conviction data, not buy signals.
f-score & z-score // on every workspace
Every stock workspace now carries a Piotroski F-Score (all nine checks shown, with any non-computable checks disclosed) and an Altman Z-Score with its zone — computed from the company's own XBRL filings.
Educational only — not investment advice. Scores and indicators are published formulas applied to as-filed data; they are screens, not verdicts, and they can be wrong.
