The period balance: money in, money out
In the Form 4 filings submitted between Sep 9, 2025 and Oct 1, 2026 there is not one open-market purchase of Fortinet, Inc.: 22 sales worth $136.2M 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 Fortinet, Inc.'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 |
|---|---|---|---|
| M | Option exercise | 55 | $25.3M |
| S | Open-market sale | 22 | $136.2M |
| F | Tax withholding (shares surrendered for taxes) | 16 | $10.7M |
| G | Gift | 7 | $0 |

How to read this data
18 of the 20 sales in the table are flagged as scheduled (10b5-1 plan): signed months ahead and executed automatically, so they say nothing about what the insider thinks today. Fortinet 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 1, 2026, and a Form 4 arrives up to two business days after the trade.
20 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.

- Who really moves the market: the types of investorWho sits on the other side of each order, and where a company's own insiders fit among them.
- Supply, demand and price: why it rises and falls constantlyHow a piece of news ends up inside the price, and why the reaction to a filed sale is rarely the one you would expect.
