The Stocks Hedge Funds Bought Most in Q1 2026

NVIDIA, Meta, and Aon led Kresmion-tracked hedge funds in Q1 2026 by breadth of buying: each was added by 8 of 21 funds, per Form 13F filings made to the SEC.

This study counts how many of Kresmion's tracked institutional managers added to or opened a position in each U.S.-listed name during the first quarter of 2026, using Form 13F holdings filed with the SEC. Breadth — how many distinct funds bought a name — is a cleaner conviction measure than a single fund's headline dollar figure, which one large allocator can skew. "Most bought" here means most-bought within Kresmion's 21-fund tracked universe, not across every 13F filer. All figures below are drawn from the Kresmion 13F dataset (`institutional_holdings`, report quarter 2026Q1, report date 2026-03-31) unless an external source is cited.

Key takeaways

How the dataset is built

As of March 31, 2026, Kresmion's 2026Q1 13F dataset contained 21 distinct fund CIKs across 18,548 holding rows and 6,003 distinct CUSIPs. A name is counted as "added" when a fund increased an existing position or opened a new one — a positive share change, or a recorded NEW_POSITION / INSTITUTIONAL_SURGE signal. Positions are grouped by CUSIP rather than ticker, because the same security can carry inconsistent ticker text across filings.

Two cleaning steps matter. First, one corrupt Berkshire Hathaway row for Alphabet (54,249,798 shares, $15.6B market value, +36.4M share change) was excluded from every aggregation; the separate, legitimate Berkshire Alphabet position of 3,585,215 shares was retained. Second, every reported figure was sanity-checked with an implied mark, defined as total market value divided by total shares held across all holders of a CUSIP.

The names funds bought most by breadth

As of March 31, 2026, three names tied for the widest buying, with 8 of 21 tracked funds adding: NVIDIA (NVDA), Meta Platforms (META), and Aon plc (AON).

NVIDIA led on both breadth and dollars: 8 funds added NVDA and 12 held it, with $8.95B of market value and 5,695,756 shares added, at an implied mark of $174.40. Meta saw 8 funds add and 14 hold, $3.23B and 2,579,868 shares added, implied mark $572.13. Aon saw 8 funds add and 8 hold, $426.9M and 1,222,341 shares added, implied mark $204.18 — notably, Aon was held by only the same 8 funds that added it.

A second cluster, each with 7 funds adding, rounds out the leaders (all as of March 31, 2026):

• EquipmentShare.com (EQPT): 7 holding; $149.1M and 7,319,986 shares added; implied mark $20.37.
• Blackstone (BX): 7 holding; $731.3M and 6,062,418 shares added; implied mark $114.99.
• Broadcom (AVGO): 10 holding; $4.02B and 5,962,347 shares added; implied mark $309.51.
• Alphabet (GOOGL), post-exclusion: 14 holding; $3.51B and 5,026,544 shares added; implied mark $287.56.
• Visa (V): 10 holding; $2.48B and 4,667,513 shares added; implied mark $279.93.
• Taiwan Semiconductor (TSM): 13 holding; $7.00B and 3,923,222 shares added; implied mark $337.95.
• Portland General Electric (POR): 7 holding; $322.4M and 3,106,967 shares added; implied mark $52.77.
• ASML Holding (ASML): 10 holding; $1.73B and 581,818 shares added; implied mark $1,320.82.

Amazon (AMZN) followed with 6 funds adding and 13 holding, $4.92B and 9,589,475 shares added, implied mark $195.49 — the largest share count added among the leaders.

The implied marks line up with market prices, a sign the underlying figures are internally consistent. NVIDIA's implied $174.40 compares with a $177.39 close on 2026-04-02, the first post-quarter trading day, a 1.7% difference. Meta's $572.13 compares with a $574.46 close (0.4%), Broadcom's $309.51 with $314.55 (1.6%), and Taiwan Semiconductor's $337.95 with $339.04 (0.3%). All four marks sit slightly below the April 2 close because 13F values are struck at the March 31 quarter-end.

Brand-new positions tell a separate story

Breadth of adding captures accumulation; brand-new positions capture fresh conviction. As of March 31, 2026, the largest verified new position by market value was Berkshire Hathaway's stake in Delta Air Lines (DAL): 39,809,456 shares worth $2,646,532,635, at an implied mark of $66.48 that matched across all five funds holding DAL.

The next four verified new positions were Pershing Square in Microsoft (MSFT), 5,654,078 shares / $2.09B (mark $370.17); Coatue Management in Equinix (EQIX), 1,090,886 shares / $1.07B (mark $980.24); Berkshire Hathaway in Alphabet (GOOGL), 3,585,215 shares / $1.03B (mark $286.86); and Viking Global in Apple (AAPL), 3,593,057 shares / $911.9M (mark $253.79). Renaissance Technologies also opened Apple at 3,075,638 shares / $780.6M. Viking added new positions in FedEx (FDX), 1,932,165 shares / $688.2M, and Meta, 1,062,575 shares / $607.9M. Lone Pine Capital opened several new positions, led by Teradyne (TER) at $555.2M and Corning (GLW) at $505.6M.

Each new-position mark was confirmed by cross-fund agreement — for example, AAPL carried an identical $253.79 mark across all 10 of its holders, MSFT $370.17 across 11 of its 12 holders, and META $572.13 across all 14.

A note on the largest percentage moves

The headline percentage increases in the dataset are not discretionary conviction. The top change values — 211,376% (Two Sigma, GH), 134,817% (Two Sigma, LMT), and 109,595% (Two Sigma, UNP) among them — reflect quant funds scaling tiny prior stubs of 1,000–5,000 shares up to full positions. The underlying marks are sane (LMT $604.39, UNP $242.62), but the percentages are mechanical rebalancing artifacts rather than signals of intent.

Frequently asked questions

How many funds does this study track?

The 2026Q1 dataset contained 21 distinct fund CIKs, not the 23 documented in Kresmion's tracking list; two funds either lacked parsed 13F coverage this quarter or share a CIK. All counts are out of the 21 funds actually present.

Why are NVIDIA, Meta, and Aon tied at the top?

Each was added by 8 of the 21 tracked funds in Q1 2026, the highest breadth of buying in the dataset. NVIDIA also led on dollars added ($8.95B), while Aon was held by only the 8 funds that added it.

What was the largest brand-new position in Q1 2026?

As of March 31, 2026, the largest verified new position by market value was Berkshire Hathaway's stake in Delta Air Lines (DAL): 39,809,456 shares worth $2.65B at an implied mark of $66.48. Pershing Square's new Microsoft position ($2.09B) was second.

How current is this data?

The data reflects positions as of March 31, 2026, the 13F report date. As of June 15, 2026, it is roughly 11 weeks old, and positions may have changed materially since the quarter-end snapshot.

What does "implied mark" mean?

It is total reported market value divided by total shares held across all holders of a security. Kresmion uses it as a pricing sanity check against quarter-end market prices, not as a per-trade execution price.
