Michael Speiser has been a consistent seller of Snowflake (SNOW) stock, with SEC Form 4 filings showing 25 open-market sales in the last two months. The transactions, all coded "S" for open-market sale, total roughly $15.8 million. The most active day was August 7, 2026, when four sales brought in about $15.6 million, including a single block worth $11 million. A similar pattern appeared on July 6, 2026, with a series of smaller sales ranging from a few hundred dollars to just over $118,000. The selling bias is one-directional. Across 198 total transactions involving two companies, Speiser has recorded $147.9 million in sales and no open-market purchases. There are no grants, option exercises, or tax-withholding events in the recent data. Every transaction is a sale, and every sale is in SNOW. The dollar amounts vary widely, from a $253 trade on July 6 to the eight-figure block in August, but the direction does not change. Speiser has not bought a share of stock through an open-market purchase in the period covered by the filings.
