David A. Duffield has filed 400 Form 4 transactions, all in a single company: Workday (WDAY). The pattern is entirely one-directional. Across all filings, he has recorded $927.4 million in open-market sales and zero dollars in open-market purchases. There are no acquisitions of any kind, whether through grants, option exercises, or conversions, in the recent data.
The most recent cluster of trades, filed for September 4, 2026, shows seven separate sale transactions totaling roughly $17.8 million. The largest single sale that day was $6.26 million, with another at $5.98 million. A conversion of derivative securities also appears on that date with a value of zero, which is a mechanical event rather than a cash transaction. On September 1, 2026, Duffield filed ten sales worth about $19.3 million, including two sales above $7 million each. The July 9, 2026 filings show seven sales totaling roughly $14.3 million.
The recent direction is consistent with the long-term record. Duffield has sold on every filing date in the sample, with no purchases in any of the 23 most recent transactions. The dollar values vary widely, from small sales near $13,898 to multi-million dollar blocks. The absence of any buy-side activity, combined with the steady stream of sales across three separate filing dates in July and September 2026, shows a clear and sustained selling bias in WDAY shares.
