Everything here is computed from official filings and shown with its method — the opposite of a proprietary score. The AI research layer moves in here too, built on these same engines.
Form 4 open-market transactions only (codes P and S) across our 91-ticker universe — grants and option exercises excluded. Same-day data; some sites delay this three months on free tiers.
No overlap right now between whales adding (latest 13Fs) and insiders buying (last 45 days) — that's the honest answer, not a broken feed.
Intersection of 13F position increases and Form 4 open-market buys. Different lags apply to each source; conviction data, not buy signals.
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.
