Berkshire May Offload $15B Portfolio After Combs Exit

Berkshire Hathaway could be repositioning up to $15 billion of its roughly $322 billion equity portfolio following the departure of a senior investment manager. The move comes as the new chief executive Greg Abel assumes greater control over investment decisions.

Estimated $15 Billion Exposure Linked to Combs

Combs is believed to have managed slightly more than 5% of Berkshire’s equity portfolio. Based on the company’s portfolio size, which has ranged between $300 billion and $322 billion, this implies an exposure of approximately $15 billion to $16 billion.

If Abel has opted to exit or rebalance these holdings, it would represent a significant portfolio adjustment. However, given the scale of Berkshire’s positions, any such move is likely to be executed gradually over multiple quarters rather than through a single large transaction.

The company has not disclosed specific allocations tied to individual managers, leaving the exact composition of Combs’ holdings unclear.

Shift Toward Core Holdings Strategy

In his first shareholder communication as CEO, Abel identified nine investments as “core holdings,” indicating these positions would see minimal trading unless there are material changes in long-term fundamentals. This signals a potential shift toward a more stable, lower-turnover investment approach.

Abel also confirmed that while Weschler will continue to manage about 6% of the portfolio, overall accountability for investment performance now rests with him. The change suggests a move away from a decentralised structure toward more centralised oversight.

The emphasis on core holdings could reduce frequent portfolio adjustments, aligning Berkshire’s strategy with long-term capital preservation and disciplined allocation.

Upcoming Filings to Provide Clarity

Investors are expected to gain clearer insights into Berkshire’s portfolio activity through upcoming regulatory filings. The company must submit its first-quarter Form 10-Q by May 2, followed by a detailed 13F filing by May 15.

These disclosures will outline changes in equity positions, including any significant buying or selling activity during the quarter. They are likely to confirm whether the reported $15 billion shift has begun and identify affected sectors.

Given Berkshire’s size and influence, even partial reallocation of such a large portion of its portfolio could impact market sentiment across multiple industries.

Strategic Implications for Investors

The reported developments highlight a transition phase for Berkshire as it moves into the post-Buffett era. Abel’s early actions suggest a focus on simplifying portfolio management while maintaining long-term investment discipline.

While the company has historically emphasised high-conviction, long-duration investments, the evolving structure under Abel may bring a more centralised and potentially less active approach to managing capital.

Until official filings are released, the scale and timing of any portfolio changes remain uncertain. However, the potential $15 billion shift underscores the significance of leadership changes at one of the world’s largest investment conglomerates.
