Q1 2026 13F filings summary

75 of the 77 super-investors we track have filed their Q1 2026 13F, disclosing a combined $1203.25B in US-listed equities. Across the cohort the quarter produced 154 new positions and 128 full exits. Below: the synthesized takeaways, the most-bought names, the biggest initiations, and the highest-conviction stocks by Cohort Conviction Score.

The quarter in five signals

  1. Alphabet (GOOG/GOOGL) is the quarter's loudest signal: Buffett nearly triples his GOOGL stake to ~$15.6B (2% → 6% of Berkshire), Armitage adds GOOG aggressively (+221%), Duan Yongping doubles, Loeb and Mandel initiate — value, growth, macro, and quality all converging simultaneously.
  2. Ackman dumps Hilton, buys MSFT at $2.1B (15% of portfolio) — a rare tech initiation from a concentrated value/activist; simultaneous exits by Gates Foundation and Armitage on the same name create a sharp divergence worth watching.
  3. SUNB (Sunbelt Rentals) is a sleeper consensus: Five distinct-style managers (Dorsey, Russo, AKO, Greenberg, Rochon) all initiate — equipment rental moat thesis crossing quality-compounder and value camps.
  4. UBER attracts a 3x add from Tepper (+242%, now 7.7% of Appaloosa) plus new positions from Dorsey and Armitage adds — platform durability thesis gaining multi-style traction.
  5. Druckenmiller exits broad ETF proxies (XLF, RSP) entirely and concentrates into NTRA (21% of portfolio) — dramatic shift from macro hedges to single-name biotech conviction.
