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.
- Buy (P) — Open-market or private purchase
- Converted (C) — Conversion of a derivative security into shares
- Gift (G) — Bona fide gift
- Other (J) — Other acquisition or disposition — the filing explains it in a footnote
