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.

Get told the moment an insider moves on FSLR
Pro watches First Solar, Inc. for you and sends a Telegram ping within moments of a Form 4 clearing EDGAR — a C-suite open-market buy, a cluster, a 10b5-1 regime break — long before it reaches the press. Add FSLR to a watchlist, see each mover's benchmark-measured track record and which legendary funds hold it, and read the full filing history instead of the last 72 hours.
The live dashboard is free to open. Alerts, watchlists, full filing history and each mover's benchmark-measured track record are Pro. Monitoring, not advice.
How to read FSLR 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.

- From the Form 4 filings First Solar, Inc.'s officers, directors and 10% owners must send the SEC within two business days of a trade. Each row on this page links to its original filing on SEC EDGAR. Share grants and option exercises are kept apart from open-market purchases and sales, because only the latter cost the insider their own money.
