AI Analysis · Q1 2026

The most unusual structural fact in GSK plc's Q1 2026 13F is not a trade — it is the absence of almost any: 13 holdings, zero increased positions, zero decreased positions, and only two micro exits (Senseonics and Harvard Bioscience, under $70k combined prior). Yet reported value dropped from about $799 million to $599 million. That ~$200 million hole is mark-to-market, not de-risking. CRISPR Therapeutics alone is 25.6% ($153 million); Wave Life Sciences is 22.1% ($132 million) — nearly half the book in two genetic-medicine names. BioNTech (13.2%) and Vir Biotechnology (12.8%) push the top four past 70%. This is a strategic biotech sleeve frozen in share terms, not a diversified manager's trading quarter — and the concentration means a single platform re-rating reprices the entire filing.

The most unusual structural fact in GSK plc's Q1 2026 13F is how little the share ledger moved. Thirteen holdings. Zero increased positions. Zero decreased positions. Two sold lines that barely register: Senseonics (~$60k prior) and Harvard Bioscience (~$7k prior). The economic story of the quarter is almost entirely price.

Reported portfolio value fell from about $799 million to $599 million. With share counts effectively static across the core book, that roughly $200 million decline is mark-to-market on a concentrated biotech sleeve — not a program of selling.
