From SEC's quarterly Form 3, 4 and 5 data sets: code P purchases and code S sales of common stock, by the date the trade happened. Where a fund and the people who control it each report the same block, it is counted once. Trades made in the last days of Q2 2026 but filed after it closed arrive with SEC's next quarterly release.
