UBS Group AG

UBS Group's 13F book grew to $666.3 billion in Q1 2026, up roughly $50B from $616.7B the prior quarter across nearly 23,000 positions. The equity core is a standard mega-cap ladder — Nvidia (2.95%), Apple (2.41%) and Microsoft (2.23%) — but the quarter's defining move was a rebuild of broad-index exposure: a new ~$10.5B Invesco QQQ position, fresh stakes in Vanguard mid-cap (VO), Russell 1000 Growth/Value (VONG/VONV) and investment-grade credit (USIG), set against a ~$7.1B sale of a separate QQQ holding. Notably, UBS trimmed its own ADR by ~$2.2B. Technology ($77B) and ETFs ($70B) are nearly even at the top of the sector mix.
