No other Workday insider filed an open-market sale during that window; Duffield was the only seller in the Form 4 data for the period. No $WDAY insider purchases or stock grants appeared in the Form 4 data alongside the sales. His position is listed in the filings as 10%+ owner rather than as an officer or director.
Congressional activity in $WDAY was far smaller in scale. Representative Gilbert Cisneros, a Democrat, disclosed a $WDAY sale on June 5, reported 27 days later on July 2. Representatives Ro Khanna, a Democrat, and Michael T. McCaul, a Republican, disclosed smaller $WDAY purchases earlier in the spring, according to STOCK Act records. Those congressional filings involved amounts far below the value of Duffield's October 6 sale.
Workday is a technology company with a market capitalization of about $39.05 billion. The stock closed at $188.96 on October 5, the session before the October 6 sales. The October 6 Form 4 was submitted the day after the transactions.
