The period balance: money in, money out
In the Form 4 filings submitted between Sep 4, 2025 and Oct 14, 2026 there is not one open-market purchase of Workday, Inc.: 67 sales worth $669.9M 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 Workday, 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 |

| C | Conversion of a derivative | 40 | $0 |

Who has traded
Over the 15 months of history, 18 distinct people or entities have filed Workday, Inc. transactions: none bought on the open market and 8 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 8 who sold on the open market (67 sales in all), the three biggest sellers account for $659.7M of the $669.9M: 98% of the money in three people.

How to read this data
20 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. Workday 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 14, 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.

- 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.
