Note: The transactions reported here refer to legal insider trading β purchases, sales, and other dealings in company securities by executives, directors, and major shareholders, which are required by law to be disclosed to the SEC via Form 4 filings within two business days of the transaction. This article covers the top 100 most significant transactions by dollar value from today's filings. This is entirely distinct from illegal insider trading, which involves buying or selling securities based on material, non-public information in violation of US federal securities law and equivalent legislation in other jurisdictions.
Insider trading activity on October 16, 2026, exhibited a decidedly bearish tilt, with sales vastly outpacing purchases. Out of 100 total trades, only 7 were buys, while 93 were sales, signaling a potential shift in market sentiment among corporate insiders. The data reveals a stark contrast between the few high-profile buys and a wave of large-scale divestments across multiple sectors.
The largest insider purchases were concentrated in a handful of companies, led by Gogoro Inc., where Director Yin Chung-Yao acquired $35.1 million worth of shares. Banco Bradesco S.A. also saw significant buying activity, with Director Rubens Aguiar Alvarez purchasing $32.0 million in stock. GameStop Corp. CEO and Chairman Ryan Cohen made a notable $22.8 million buy, while QVC Group Inc. and Borr Drilling Limited rounded out the top buys with $16.7 million and $11.8 million purchases, respectively, by GoldenTree Asset Management and Director Tor Olav Troim.
In contrast, the sales side was dominated by massive transactions, particularly in the healthcare and tech sectors. Eli Lilly and Company saw the largest proposed sale of the day, with shareholder Lilly Endowment, Inc. offloading $368.7 million in stock. Palo Alto Networks CEO Nikesh Arora proposed a $201.4 million sale, while Elastic N.V. faced two major divestments: CMXI B.V. proposed selling $191.0 million, and Director Steven Schuurman sold $188.3 million. Kinetik Holdings Inc. completed the top sales with a $109.5 million transaction by ISQ Global Fund II GP LLC.
