Berkshire Hathaway’s first quarterly portfolio update under new Chief Executive Greg Abel — the conglomerate’s initial Form 13F since Warren Buffett stepped down — offers a fresh read on large-scale investor positioning that many digital-asset market participants monitor for signals about cross‑market risk appetite. The filing, released on May 15 for the quarter ended March 31, outlines how the post‑Buffett era is beginning to take shape and where one of the market’s most influential pools of capital is redeploying — or withholding — funds.

Market Movement

The latest disclosure shows Berkshire’s equity portfolio at approximately $263 billion, down from around $274 billion in the previous quarter. Despite the overall decline, the mix remains tightly concentrated, with the top 10 positions accounting for more than 90% of total assets. That persistent concentration underscores a preference for large, liquid exposures that can be scaled — a trait closely followed by traders who study flows and positioning across asset classes for clues about risk trends.

Apple retained its status as Berkshire’s single largest holding, representing roughly 22% of the portfolio. Other major positions continued to include American Express, Coca‑Cola, and Bank of America. The ongoing dominance of a handful of names, anchored by Apple, reinforces the idea that Berkshire’s core equity stance remains centered on established, cash‑generative franchises even as individual line items shift at the margin.

Key Drivers

Within that concentrated framework, the most notable portfolio changes came on both the buying and selling sides. Berkshire significantly expanded its exposure to Alphabet by adding 36.4 million Class A shares and 3.6 million Class C shares, lifting the company’s combined portfolio weighting in the Google parent by 4.37 percentage points. In media, Berkshire purchased 10.1 million shares of The New York Times Company. In homebuilding, the firm increased its Lennar stake through the purchase of 3 million Class A shares and 56,723 Class B shares.

The filing also marked a return to airlines. Berkshire acquired 39.8 million shares of Delta Air Lines, signaling renewed exposure to a sector it had previously moved away from. In the retail space, Berkshire initiated a new position in Macy’s with 3 million shares, adding another consumer‑facing holding to the mix.

On the selling side, the company trimmed energy exposure by cutting its Chevron position by 45.8 million shares, a 35.17% reduction. It also pared back stakes in Nucor, DaVita, Liberty Media, and Bank of America. Several holdings were fully exited: Visa, Mastercard, UnitedHealth, Domino’s Pizza, Aon, Pool Corporation, Amazon, Charter Communications, and Diageo. Share count disclosures underscore the scale of these changes, including the sale of 8.3 million Visa shares, 4 million Mastercard shares, 5 million UnitedHealth shares, and 2.3 million Amazon shares.

Even with these adjustments, Berkshire’s most striking line item may be what it has not yet deployed. The firm continues to hold an enormous cash reserve of approximately $397 billion, preserving flexibility for future opportunities. That cash position remains a focal point for investors across markets who track the timing and size of major allocations as a barometer of broader risk tolerance.

Investor Reaction

The portfolio update arrives amid a period of relative underperformance in Berkshire’s shares since Buffett’s retirement announcement. The stock has lagged the S&P 500 by roughly 10 percentage points, reflecting investor debate over whether the so‑called “Buffett Premium” has faded as markets adjust to the leadership transition. Some analysts view current pricing as closer to intrinsic value, with the stock trading at about 1.4 times book value — a level that suggests confidence in the underlying businesses but limited willingness to pay a higher multiple without fresh evidence of outsized compounding.

Against that backdrop, attention is fixed on how Abel approaches capital allocation in an environment still characterized by elevated asset prices and a scarcity of attractively priced, large‑scale acquisitions. The first 13F under his watch provides a baseline: a willingness to build in select technology, media, and consumer names; a readiness to reduce certain cyclical or capital‑intensive exposures; and an insistence on maintaining a substantial cash buffer. For market participants who map cross‑asset behavior, that combination points to a measured stance rather than a wholesale rotation.

Broader Impact

For observers of trading activity and investor movements, the changes carry several implications. First, the continued concentration in a handful of large positions, with Apple still accounting for roughly 22% of the portfolio and the top 10 holdings exceeding 90% of assets, reaffirms Berkshire’s preference for scale and liquidity. That preference tends to limit sudden, market‑moving reallocations while still allowing room for incremental tilts — as evidenced by the meaningful add to Alphabet and selective new positions in Delta Air Lines and Macy’s.

Second, the 35.17% reduction in Chevron alongside trims in Nucor, DaVita, Liberty Media, and Bank of America illustrates targeted risk management rather than a uniform de‑risking. In aggregate, these shifts align with a posture that emphasizes balance sheet strength and optionality. The roughly $397 billion cash reserve is central to that posture, giving Berkshire the latitude to respond to dislocations without forcing commitments at prices it deems unattractive.

Third, the full exits from Visa, Mastercard, UnitedHealth, Domino’s Pizza, Aon, Pool Corporation, Amazon, Charter Communications, and Diageo streamline the equity book and potentially free capacity for future opportunities. The disclosed share sales — including 8.3 million Visa, 4 million Mastercard, 5 million UnitedHealth, and 2.3 million Amazon — underscore the operational scale at which Berkshire adjusts exposures when conviction changes.

Finally, the leadership context matters. Buffett officially stepped down as CEO at the end of 2025 after six decades, and he remains chairman and an advisor. Abel’s first quarter at the helm, as reflected in the March 31 holdings released on May 15, suggests continuity tempered by selective recalibration. For markets that interpret large‑allocator behavior as a read on prevailing risk tolerance, the message is steady but vigilant: concentrated where conviction is highest, active at the edges, and patient with a sizable cash cushion until valuations or conditions press a clearer advantage.

For now, Berkshire’s equity book provides more insight into positioning than it does an immediate directional call for risk assets. The signals are subtle but consistent — an incremental reshaping of exposures, a robust liquidity stance, and a focus on enduring businesses — all of which will remain in focus as investors assess how Abel navigates capital deployment in the quarters ahead.
