What the moves add up to

Whale Rock’s Q2 2026 activity points to a clear rotation toward semiconductors and AI-adjacent infrastructure, with the most consequential top move being a major increase in Advanced Micro Devices. The firm added to AMD (share count up 2081.2%) and also built positions in Ttm Technologies (up 20.4%), Coherent (up 25.3%), and Fabrinet (up 21.8%). On the “new” side, it initiated Astera Labs alongside smaller new stakes such as Snowflake, Twilio, and Seagate Technology Hldngs Pl.

That theme is reinforced by the trimming actions concentrated among prior large holdings, led by a pullback in Sandisk (share count down 25.4%) and reductions across Alphabet (down 10.3%), Corning (down 2.8%), Mks (down 2.7%), Celestica (down 2.8%), and Bloom Energy (down 2.8%). Despite the exits—such as Advanced Energy Inds, Roblox, and Arm Holdings—the top-10 concentration remains high at 59.3% of the portfolio, suggesting the quarter’s reshuffling largely reweights existing conviction rather than broadly diversifying into many new positions.

Context

How to read this filing

A Form 13F is a quarterly snapshot institutional managers with over $100M in US-listed assets must file within 45 days of quarter end. It shows long equity positions only: no short book, no cash, no non-US listings, no timing inside the quarter. Treat it as a delayed map of where the manager's conviction sat on the reporting date — not a live portfolio, and not a buy list.

Positions may have changed since the reporting date. Weight changes also reflect price moves, not only buying or selling — the action tags on this page are derived from share counts, which do not move with price.
