Warren Buffett's Successor, Greg Abel, Pared Down Bank of America, and Piled Into a Virtual Monopoly That's Now Berkshire's 3rd-Largest Holding

Berkshire Hathaway’s 13F shows Greg Abel cut Berkshire’s Bank of America position by 53% (~549.5 million shares) over the eighth straight quarter of selling, despite earlier BofA profit-taking likely contributing. In contrast, Berkshire heavily increased Alphabet after a June 1 $10B private placement, buying 24.54M Class A and 23.60M Class C shares, lifting Alphabet to a combined ~$36.6B market value and making it Berkshire’s third-largest holding. The shift suggests a reallocation away from interest-rate-sensitive banking toward AI-led tech/cloud exposure (Alphabet’s Google Cloud sales up 82% YoY in the cited quarter), which may support relative outperformance but signals portfolio re-risking.

Analysis

This reads less like a single-stock endorsement and more like a capital-allocation regime change. Berkshire is implicitly telling the market that low-growth, balance-sheet-heavy financials no longer deserve the same portfolio weight as high-quality cash compounding platforms, which is a relative negative for BAC and a relative positive for GOOG. The key mechanism is not earnings momentum today; it is the market’s willingness to pay a higher multiple for durable free cash flow with AI upside versus a bank whose returns are still tightly tethered to rates and deposit beta.

Second-order, the signal matters because Berkshire has historically been a patient marginal buyer in large caps. If that bid is being removed from money-center banks, the weakest rerating candidates are the most rate-sensitive names with the least operating leverage to a steeper curve; that keeps BAC and similar lenders capped even if fundamentals are merely stable. On the other side, GOOG may attract incremental long-only flows not because investors suddenly believe every AI product will monetize, but because Berkshire’s stamp of approval reframes it as a cash-flow fortress with optionality rather than a pure ad-tech proxy.

The contrarian risk is that the market overreads the 13F as a clean AI signal. The better read is quality selection, not AI beta chasing: if Alphabet’s capex intensity rises faster than monetization, the multiple can compress even with good top-line growth. For BAC, the thesis breaks if net interest income stabilizes faster than feared or buybacks offset the lost Berkshire demand; for GOOG, it breaks if margin pressure from AI investment becomes visible over the next 1-2 quarters.

Key Decisions for Investors

• Go long GOOGL/GOOG vs short BAC on a market-neutral basis over the next 1-3 months; use a small initial size and add only on post-news weakness. The trade is a valuation-dispersion bet: durable compounder re-rates while rate-sensitive bank multiple stays capped. Falsify if BAC shows clear NII stabilization and capital return acceleration, or if GOOG guides to materially higher capex with no margin offset.
• If initiating exposure to GOOG, buy pullbacks rather than chasing the first-day move; a 1-2 month call spread is preferable only if implied vol remains contained. Risk/reward is strongest if the stock digests the 13F headline and then re-anchors on cash flow quality.
• Avoid adding BAC long here until the market sees an actual earnings inflection, not just a cheap-looking book multiple. Berkshire’s continued selling is a sentiment overhang that can persist for quarters, and the name needs a clear catalyst in rates or buybacks to break that ceiling.
• Keep BRK.B on watch as a low-volatility expression of the same thesis, but do not treat it as a fast catalyst trade. Any premium from Abel's capital-allocation credibility is likely to accrue slowly over 6-18 months rather than in the next few sessions.
