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.

How to read WAT insider activity
- Open-market purchase (code P)
- An insider spending their own money at market price. This is the only buy code that reliably carries signal — it is a decision, not compensation.
- Grants and option exercises (codes A, M)
- Scheduled compensation. Most "insider buying" headlines are really this, which is why InsiderPulse weights it at a fraction of a real purchase.
- Cluster buy
- Two or more different insiders buying on the open market in the same window. One executive buying can mean anything; three is much harder to explain away.
