Jeremy Grantham's GMO made its largest sector move in Q2 2026 inside the very corner of the market it publicly warned against: Information Technology received a net $2.5B, equal to roughly 6% of the firm's disclosed book.
Industrials and Financials also saw increased weight, with GMO adding a net $987.9M and $819.6M respectively — each representing about 2% of book. On the other side, Materials and Energy were trimmed by modest amounts, $146.5M and $101.8M, each less than 1% of book.
Across the two quarters, roughly $5.9B — about 14% of the book — was reshuffled in total. The scale of the Information Technology build stands out given GMO's stated view that share issuance will weigh on US equities before the market can see how thin AI returns on investment actually are.
The thread connecting these moves is tension: GMO's public bearishness on US equities and AI economics sits alongside a portfolio that, in practice, added its heaviest dollar weight to the sector most exposed to both.
