Summary (tl;dr)

Berkshire Hathaway, under its new CEO Greg Abel, has significantly reshuffled its investment portfolio, tripling its stake in Alphabet and making a notable new investment in Delta Air Lines, while exiting numerous other holdings.

Essential Background

For decades, Berkshire Hathaway's investment strategy was synonymous with its renowned CEO, Warren Buffett, known for his long-term, value-oriented approach and often avoiding technology stocks or industries he deemed complex. At the end of 2025, Buffett officially stepped down as CEO, handing control of the conglomerate and its investment portfolio to Greg Abel, though Buffett remains chairman and an advisor. This transition marked the beginning of a new era for the investment giant, with investors keenly awaiting the first major portfolio moves under Abel's direct leadership.

The Full Story

Recent regulatory filings, specifically the 13F filings for the first quarter of 2026 disclosed around May 15-18, 2026, revealed a substantial overhaul of Berkshire Hathaway's investment portfolio, signaling the distinct investment philosophy of new CEO Greg Abel. The company notably more than tripled its stake in Alphabet, the parent company of Google, acquiring additional shares worth billions and making it one of Berkshire's largest holdings. In a surprising move that departs from Warren Buffett's past aversion to the sector, Berkshire Hathaway also initiated a new multi-billion dollar stake in Delta Air Lines, despite Buffett having famously sold all airline stocks in 2020. Concurrently, Berkshire Hathaway divested entirely from numerous positions, including Domino's Pizza, Amazon, Visa, Mastercard, UnitedHealth Group, and others. While still its largest holding, the company also significantly reduced its stake in Apple. These changes represent Abel's first major statement in reshaping the equity portfolio since taking the helm.

Why It Matters

These significant shifts in Berkshire Hathaway's portfolio are closely watched by investors globally as they provide insight into the strategic direction under Greg Abel, moving beyond the long-established Warren Buffett era. The substantial increase in Alphabet and the new investment in Delta Air Lines suggest a potential shift towards greater exposure to technology and a re-evaluation of industries previously avoided by Buffett. This rebalancing could influence broader market sentiment and investment trends, especially considering Berkshire's reputation and vast holdings. Investors are keen to understand if Abel's strategy will continue to deliver the long-term returns characteristic of Berkshire Hathaway under Buffett.
