RenTech Boosts Cybersecurity Stakes, Dumps AppLovin Amid Q2 Portfolio Shake-Up

Renaissance Technologies made significant changes to its portfolio in the second quarter of 2026. The fund added a new $572 million stake in CrowdStrike Holdings, Inc., which is listed on the NASDAQ under the ticker symbol CRWD.

The investment firm liquidated its holdings in AppLovin Corporation (APP) and nearly tripled its position in NVIDIA Corporation (NVDA). Additionally, it dramatically reduced its stake in Micron Technology, Inc. (MU), according to its latest 13F filing.

Renaissance Technologies' moves in the second quarter demonstrate a shift in its investment strategy. The fund's increased focus on CRWD and NVDA suggests a growing interest in cybersecurity and technology sectors. On the other hand, its reduced stake in MU indicates a decreased confidence in the semiconductor market.
