What these mean— the action is the SEC’s own Form 4 transaction code. Only a buy or a sell is an open-market trade; the rest are transfers, awards and exercises, which is why they carry no price.
- Sell (S) — Open-market or private sale
- Tax withheld (F) — Shares withheld to pay tax or an exercise price
- Gift (G) — Bona fide gift
