Greg Abel Recently Plowed $4.2 Billion Into Warren Buffett's Favorite Stock, and It Wasn't Apple

Berkshire Hathaway restarted large-scale share repurchases under new CEO Greg Abel, buying back $235 million in Q1 2026 and $4.2 billion in Q2, after no buybacks in Buffett's final year. Buffett had authorized $77.8 billion of repurchases from 2018 through 2024; Berkshire now has more than $365 billion of cash, well above its $30 billion minimum liquidity threshold for buybacks. The article frames Abel's actions as a shareholder-friendly continuation of Buffett's capital-allocation strategy, alongside more than $20 billion invested in Alphabet.

Analysis

The resumed repurchase program is more important as a capital-allocation signal than as a near-term EPS lever: even an annualized $17B pace would retire a low-single-digit percentage of float. Its valuation impact depends entirely on whether repurchases occur below Berkshire’s conservatively marked intrinsic value; at a premium to book-value growth, buybacks merely concentrate the portfolio’s equity-market and insurance-cycle exposure. The immediate read-through is modestly positive for BRK.B, but the 1-3 month catalyst is confirmation that the pace persists rather than a single-quarter deployment.

The larger underwriting issue is succession credibility. Abel’s willingness to deploy capital could narrow a transition-related conglomerate discount, but it also increases the risk that Berkshire shifts from opportunistic to habitual capital deployment at elevated asset prices. A material Alphabet position, if confirmed in subsequent filings, would increase look-through mega-cap technology concentration after the Apple reduction; that weakens the perception of Berkshire as a differentiated defensive compounder and raises correlation with QQQ during risk-off technology unwinds.

Contrarian view: the market may overvalue buybacks as evidence that management sees deep undervaluation. Berkshire’s cash balance earns meaningful short-duration income, so aggressive repurchases become less attractive if Treasury yields remain elevated and acquisition financing conditions improve. The thesis is falsified if repurchases cease again, insurance underwriting deteriorates, or cash falls without a commensurate increase in per-share operating earnings and book value growth over the next two reporting periods.

Key Decisions for Investors

• Maintain a modest long BRK.B versus SPY for 3-6 months only if the next quarterly filing confirms continued repurchases and per-share operating earnings growth; target 5-8% relative outperformance, with exit on a repurchase pause or material underwriting miss.
• Do not chase BRK.B solely on the reported quarterly authorization. Add only on broad-market weakness or if the stock underperforms SPY by 5%+ while capital deployment remains disciplined; risk is that buyback accretion is immaterial at prevailing valuation.
• Monitor Berkshire’s next 13F and annual report for independently verifiable Alphabet exposure. If a large GOOG stake is confirmed, reduce any existing BRK.B/QQQ diversification assumption and consider hedging BRK.B beta with a partial QQQ short during periods of stretched mega-cap valuation.
• For AAPL, treat Berkshire’s completed stake reduction as a reduced technical-overhang variable rather than a fresh fundamental catalyst. Maintain exposure based on iPhone and services estimates; a renewed Berkshire sale disclosure would be a sentiment negative but not, by itself, a reason to short.
