The period balance: money in, money out
In the Form 4 filings submitted between Oct 14, 2025 and Oct 2, 2026 there is not one open-market purchase of Albemarle Corporation: 6 sales worth $7.4M and zero dollars bought.
Only codes P and S count, where an insider puts in or takes out their own money. A selling balance like Albemarle Corporation's is the norm in the S&P 500, where much of the pay comes as stock. It is not a recommendation to buy or sell: it is what was filed.
Every transaction, code by code
| Code | What it means | Trades | Reported amount |
|---|---|---|---|
| A | Grant or award | 38 | $2.6M |
| F | Tax withholding (shares surrendered for taxes) | 19 | $5.8M |
| S | Open-market sale | 6 | $7.4M |
| M | Option exercise | 2 | $0 |
| G | Gift | 1 | $5.0M |
| Total | Everything filed in the period | 66 | $20.8M |
31 of the 66 rows carry no usable amount on the Form 4: they count as trades and add $0. The code labels come from the SEC index.

How to read this data
None of the 6 sales in the table is flagged as scheduled (10b5-1 plan), the kind signed months ahead and executed automatically. Albemarle has no open-market purchase (code P) in the history, the most common case in the S&P 500: insiders are already paid in stock. The latest filing is from Oct 2, 2026, and a Form 4 arrives up to two business days after the trade.
19 of the 20 rows in the table carry footnotes from the Form 4 itself, folded into the code column and copied verbatim; a row with no footnote means the filing has none.
