6 filingsEvery Form 4 on record, with outcomesPro →

Outcomes measure each position — the first buy in a stock and every buy within 182 days — against the closing price ~6 months (120 trading days) later, with the S&P 500 over the same span for context. Pre-scheduled 10b5-1 plan trades are excluded from the record. Positions are estimated from the latest reported post-transaction holdings, split-adjusted, at the latest close. Built from SEC Form 4 filings and market prices — past outcomes, not predictions or advice.
