Greg Abel Is Reshaping Berkshire's Portfolio. Here's Who's In and Who's Out.

After nine months as Berkshire Hathaway CEO, Greg Abel has identified Apple, American Express, Coca-Cola and Moody’s as core holdings, alongside Japan’s five largest trading houses; Alphabet has grown to 10.6% of the portfolio after Berkshire invested tens of billions of dollars. Berkshire trimmed Bank of America in Q2, initiated a Delta position equal to 1.3% of the portfolio, increased housing exposure including Lennar, and resumed share repurchases. The article frames the portfolio changes as measured and discusses possible headwinds from volatile oil prices and high mortgage rates, while noting that future capital returns may become more prevalent.

Analysis

The investable signal is less “Abel is copying Buffett” than a change in the market’s burden of proof: Berkshire may face greater pressure to explain how its unusually large cash balance compounds if attractive acquisitions remain scarce. That could support BRK.A through repurchases, but only if management is willing to buy at prices it considers attractive; pressure to deploy cash is not itself a reason to expect faster buybacks. Watch repurchase disclosures alongside cash levels and acquisition activity.

Alphabet’s enlarged role adds a different portfolio risk: Berkshire’s results become more exposed to the durability of digital advertising and the economics of AI investment. This is not a clean read-through to all AI beneficiaries, and a portfolio stake does not establish Berkshire’s view on the sector’s valuation. Conversely, reduced conviction in BAC, CVX or OXY should not be inferred simply from their omission from a “core” list; future filings and stated thesis changes matter.

Over 1–3 months, quarterly filings and any explicit capital-return policy are the clearest catalysts. Over 6–18 months, rates and affordability will govern the housing exposure represented by LEN, while oil and jet fuel can overwhelm company-level progress at CVX, OXY and DAL. The contrarian point: portfolio changes are reported with a lag, so reacting to a headline about holdings risks trading stale information. The thesis weakens if repurchases remain absent despite ample cash and a favorable valuation, or if Berkshire reduces GOOG while AI-related spending fails to translate into durable economics.

Key Decisions for Investors

• Treat BRK.A as a conditional capital-allocation watch, not an automatic buyback trade. Reassess after filings disclose repurchases and cash deployment; a sustained absence of repurchases despite management describing the shares as attractive would falsify the capital-return catalyst.
• Do not trade BAC, CVX or OXY on omission from Abel’s core list alone. Track Berkshire’s next ownership filing and any change in stated fundamentals; consider reducing exposure only if actual trims or weaker company-level outlooks confirm the signal.
• For housing, LEN is a rate-sensitive, longer-horizon watch rather than an immediate rebound call. A sustained decline in mortgage rates and improving orders/cancellations would strengthen the thesis; renewed rate increases or worsening demand indicators would invalidate it.
• Avoid treating Berkshire’s GOOG position as a broad AI endorsement. Monitor Alphabet’s advertising resilience and AI-related economics; deteriorating monetization alongside rising investment would challenge the growth thesis.
