Jim Simons' quantitative hedge fund, Renaissance Technologies, established a significant new position in Amazon (AMZN) during the second quarter of 2026. According to its latest quarterly disclosure with the SEC, the firm acquired 2.29 million shares valued at approximately $546 million as of June 30. This disclosure reflects a holding at the end of the quarter and is not indicative of a same-day trade.
The investment occurred during a period of heavy but mixed trading in Amazon among major hedge funds, with some large investors buying aggressively while others reduced their stakes. It also coincided with a strong financial quarter for the tech giant, which reported Q2 revenue of $200.6 billion and earnings per share of $5.75, both beating analyst expectations.
