The period balance: money in, money out
In the Form 4 filings submitted between Sep 4, 2025 and Sep 15, 2026 there is not one open-market purchase of F5, Inc.: 53 sales worth $30.7M 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 F5, 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 |

Who has traded
Over the 15 months of history, 18 distinct people or entities have filed F5, Inc. transactions: none bought on the open market and 13 sold. Counted by CIK, the fixed number the SEC gives each filer, and not by name, which each filer types their own way.
Of the 13 who sold on the open market (53 sales in all), the three biggest sellers account for $18.6M of the $30.7M: 61% of the money in three people.

How to read this data
17 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. F5 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 Sep 15, 2026, and a Form 4 arrives up to two business days after the trade.
18 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.

- What the efficiency hypothesis says and what it does NOT sayIf an insider's purchase is public and anyone can read it, is there any information left in it? That is the exact question that brings people here.
- 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.
