Too soon to tell. 1 quarter has finished so far. We show a record once 3 have.

Integra Lifesciences (IART) Bought May 23, 2024 · $1.5M · 52,641 shares Behind typical Jun 30, 2024 $29.14 → Dec 31, 2024 $22.68 · −22.2% (typical stock +3.9%)

Each row is one stock in one quarter, however many buys it took. We take the stock's price at the end of that quarter and again 6 months later, and compare it with the typical stock over the same dates. Prices are quarter-end values from funds' 13F reports (the middle value across 3 or more funds), through Sep 30, 2026. Moves past 3 times up or down, mostly stock splits, are left out. How we tested this.

Past results. This is data, not advice.

Where this data comes from. Insider trades, fund holdings, activist stakes and company results come from public SEC EDGAR filings (Forms 4, 13F, 13D/13G, 10-Q and 8-K). Congress trades come from the STOCK Act reports members file with the House Clerk and the Senate. Daily closing prices come from post-no-preference/stocks on DoltHub, a community-run database shared under CC BY-SA 4.0; the prices we show stay under that license. They are each day's close, not live or official exchange prices.
