In a 13F filing reflecting its portfolio as of June 30, 2026, Whale Rock Capital disclosed a 25% reduction in its SanDisk Corp. (SNDK) stake, selling approximately 203,000 shares. Despite the sale, the data storage company remains the firm's largest holding, with its portfolio weight increasing from 6.56% to 10.89% due to the stock's significant appreciation.
This disclosure comes after a period of massive growth for SanDisk, whose stock surged in 2026 on the back of strong demand for AI data center storage. It's important to note that 13F filings are submitted with a delay, meaning this trade occurred before a July sell-off that impacted many AI-related stocks. SanDisk was a top performer for Whale Rock in the first half of 2026, and this move may represent profit-taking after a substantial run-up.
