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.
