2026 Q1 13F Review: Crowding Into AI Compute, Mega-Caps Broadly Trimmed

This review is built from the latest 13F filings of the 34 gurus tracked on GuruTrack as of March 31, 2026 (Q1 2026), spanning 7,382 US stocks and roughly $1.02 trillion in disclosed long market value. We summarize this quarter's new positions, adds, trims/exits and crowded themes. All figures reflect 13F price-return disclosures, not realized P&L, are typically lagged up to 45 days, and are for research only.

At a glance

• Crowding concentrates in leaders: the most widely held names are all AI-compute and platform mega-caps — TSMC, Alphabet, Amazon, Meta, NVIDIA.
• Mega-caps were also trimmed: the stocks cut or closed by the most managers this quarter are likewise Microsoft, Amazon and NVIDIA — clear two-way churn.
• Theme leadership is unchanged: AI/compute, semiconductors, robotaxi and advanced packaging remain the most crowded concepts by holder count.

Most-opened new positions

By how many gurus newly opened the position this quarter (NEW):

• EquipmentShare (EQPT) — 6 gurus opened
• Indivior (INDV) — 5
• Forgent Power (FPS) — 5
• Versant Media (VSNT) — 5
• Lumentum (LITE) — 5 (also trimmed by others)
• Alphabet (GOOGL), Micron (MU), Meta — 4 new openers each, reinforcing existing holders

The top of the new-position list skews toward small- and mid-caps, suggesting managers are still diversifying beyond the leaders — while Alphabet, Meta and Micron appearing here shows AI-chain leaders keep drawing fresh capital.

Most-added positions

By how many gurus added to the position this quarter (ADD):

• TSMC (TSM) — 10 gurus added, among the top net inflows
• NVIDIA (NVDA) — 8 added (though net flow across the sample is negative — adds and trims coexist)
• Meta — 7
• Sea Ltd (SE) — 7
• Alphabet (GOOGL) — 6, with one of the largest net inflows on the board
• Lockheed Martin (LMT), Coeur Mining (CDE), Amer Sports (AS) — 6 each

TSMC was the strongest add-consensus name this quarter. Combined with rising crowding in advanced packaging (CoWoS), the "sell the shovels" thesis across the AI-compute chain remains intact.

Most-trimmed / closed positions

By how many gurus trimmed or closed the position this quarter (TRIM / CLOSED):

• Microsoft (MSFT) — 16 gurus trimmed/closed, about -$16.4B net outflow, the largest on the board
• Amazon (AMZN) — 14, about -$3.8B net outflow
• Alphabet (GOOGL) — 10 (but heavy adds too, so net flow stays positive)
• TSMC (TSM) — 9 (adds and trims coexist)
• NVIDIA (NVDA) — 8
• UnitedHealth (UNH) — 7, about -$2.6B net outflow

Note the heavy overlap between the trim list and the add/held lists — the same mega-caps were bought by some managers and taken off the table by others. That is classic churn of leader-stock chips across institutions, not a unified bearish call.

Crowding: most widely held

Ranked by the number of gurus holding the stock this quarter (holder count):

1. TSMC (TSM) — held by 21 gurus
2. Alphabet (GOOGL) — 19
3. Amazon (AMZN) — 19
4. Meta — 18
5. NVIDIA (NVDA) — 17
6. Microsoft (MSFT) — 17
7. Apple (AAPL) — 13
8. Broadcom (AVGO) — 13

By held market value, Apple (~$70.6B), Alphabet (~$25.9B) and NVIDIA (~$16.7B) lead — a handful of mega-caps concentrate the core of guru portfolios.

Crowding: hottest concepts

Ranked by the number of gurus holding the concept's constituents this quarter (sector buckets excluded):

• Warren Buffett · Berkshire — 27 gurus
• Duan Yongping — 25
• AI & Compute — 25
• Robotaxi & AV — 25
• Elon Musk · Tesla & SpaceX — 24
• Tim Cook · Apple Supply Chain — 23
• Semiconductors — 21
• Advanced Packaging (CoWoS) — 21

At the theme level, AI compute + semiconductors + advanced packaging form one full supply-chain cluster, while robotaxi keeps its high profile. Follow-the-value baskets around Buffett and Duan Yongping remain the gurus' largest common denominator.

Takeaway

Q1 2026 guru positioning shows a "concentrated leaders, two-way churn" pattern: crowding stays in the AI-compute chain and platform mega-caps, yet the same names see clear add/trim divergence, with Microsoft and Amazon cut by the most managers. For ordinary investors, the trend and the consensus structure carry more signal than any single quarter's single trade.
