Transaction types are the SEC Form 4 codes: open-market purchases (P) and sales (S) are the only rows that reflect open-market conviction. Awards/vesting (A), option exercises (M/X/C), shares withheld for taxes (F) and gifts (G) are compensation or mechanical, not buying or selling on the open market. Sales may be planned and non-discretionary (e.g. a Rule 10b5-1 plan); open-market buying is not a recommendation to buy. Informational only — not financial advice.
