Berkshire Hathaway Hits Record Highs as Investors Rotate from AI to Abel’s Defensive Strategy

Key points

• Class A and B shares set record closing highs in October 2026, surpassing levels from before the May 2025 announcement of Warren Buffett’s retirement.
• The stock recovered from a 14-15% drop in the months following the 2025 shareholders meeting, where Buffett stepped down as CEO.
• Berkshire’s B shares gained nearly 9% in October, outperforming the S&P 500 and the NYSE Fang+ index, which fell 4.8%.
• Investors are rotating out of AI and megacap tech due to concerns over infrastructure spending and profit sustainability.
• Berkshire holds over $350 billion in cash and equivalents, with annual after-tax earnings near $50 billion from diverse businesses.
• CEO Greg Abel is leveraging cash for buybacks and investments, including a $930 million stake in Italian tech firm Bending Spoons.

Background

Berkshire shares fell sharply after Buffett’s 2025 retirement announcement, with fears that the 'Buffett premium' was evaporating. By August 2025, shares had lost over 14% of their value. Recent archive coverage notes that Abel’s strategic shifts, including tech investments and buybacks, have driven a recovery, with the company benefiting from higher interest rates on its cash pile and gains in traditional value holdings.

How outlets are covering it

CNBC highlights the 'Buffett blues' reversal, noting that the market has accepted Greg Abel as a capable successor who is effectively deploying cash. It emphasizes Berkshire as the 'ultimate anti-AI play' due to its defensive cash position. Yahoo Finance’s data, while partially obscured by technical errors, implies a broader market context where chip and AI stocks are volatile, contrasting with Berkshire’s stability. Both sources agree on the outperformance of Berkshire relative to tech indices, but CNBC focuses on the leadership transition narrative, while the market data suggests a broader rotation away from AI-driven momentum.

Why it matters

The rally signals a shift in investor sentiment from high-growth AI stocks to defensive, cash-rich megacaps. It validates the market’s confidence in Greg Abel’s leadership and Berkshire’s diversified, low-volatility strategy, which is increasingly attractive amid concerns over AI infrastructure spending and profit sustainability.

What to watch

Investors will watch how Greg Abel continues to deploy Berkshire’s $350 billion cash pile, including potential further investments in tech or buybacks. The performance of Berkshire’s Alphabet stake and energy holdings will also be monitored as indicators of its exposure to AI and infrastructure trends.
