Berkshire Hathaway's Quiet Pivot: Occidental Stake Crosses the Quarter Mark

Berkshire raises Occidental stake to 26.5%, returns to net buying, resumes buybacks, and settles HomeServices legal case.

Warren Buffett's sprawling insurance-to-railroads empire has spent the summer redrawing its investment map, and the latest brushstrokes reveal a deepening conviction in one Texas oil driller above all others. A regulatory filing released in late August confirms that Berkshire Hathaway now commands roughly 26.5 percent of Occidental Petroleum, having snapped up 264,941,431 additional shares valued at about $12.9 billion. For a holding company that historically preferred minority stakes of 10 percent or less, owning more than a quarter of any listed business marks a notable departure — and signals that Greg Abel, now steering capital allocation, sees long-term value in Occidental's energy and chemicals franchise that few peers can match.

The Occidental build-out did not occur in isolation. It formed the centerpiece of a broader second-quarter buying spree that flipped Berkshire back into net-purchase territory for the first time in fourteen quarters. The numbers tell the story plainly: roughly $23.5 billion in new equity acquisitions against just $3.7 billion in sales. That swing — disclosed about a month ago — has been digested by the market with notable calm; shares have drifted roughly 2.3 percent lower since the figures landed.

A Portfolio in Motion

The latest 13F filing, dated August 20, fleshes out the direction of travel. Berkshire expanded its Alphabet position by 83 percent to approximately 106 million shares, added to homebuilders Lennar and D.R. Horton, and boosted holdings in Delta Air Lines and Macy's. On the selling side, the company trimmed Bank of America, Capital One, Kroger, and DaVita. The secondary source adds Nucor and Constellation Brands to the reduction list, while noting that cornerstone positions in Apple, American Express, and Coca-Cola were left untouched.

Meanwhile, the buyback engine — dormant through all of 2025 — has sputtered back to life. After a token $235 million in the first quarter of 2026, Berkshire repurchased roughly $4.5 billion of its own stock in the second quarter, the most aggressive buyback activity since early 2024. Management's willingness to deploy capital at those levels suggests they viewed the shares as attractively priced during the period.

Tokyo Marine's Australian Target

Adding a fresh strategic wrinkle, Reuters reported on August 25 that Japan's Tokio Marine has identified Australia's Suncorp as its preferred acquisition target after weighing multiple options. The news carries indirect significance for Berkshire holders: insurance remains one of the conglomerate's foundational pillars, and the movements of major global underwriters can offer clues about pricing power and competitive dynamics across the sector. For now, however, Berkshire's own portfolio decisions remain firmly anchored in U.S. equities.

Legal Closure on the HomeServices Front

Mid-August brought resolution to a long-running legal overhang. An appellate court in St. Louis upheld a settlement exceeding $1 billion tied to commission-fixing class actions in the U.S. residential real estate market. Berkshire's HomeServices of America subsidiary will shoulder $250 million of that total. With the case now legally settled, the matter no longer threatens additional balance-sheet strain — a modest but welcome cleanup for the conglomerate.

Market Reaction: Measured, at Best

Despite the flurry of activity, Berkshire's share price has remained remarkably steady. The stock closed at €650,000.00, down 0.1 percent on the day. Over the past month, it has slipped 2.8 percent, though it still holds a 2.0 percent gain for the year to date. At 5.2 percent below its August 52-week high of €686,000.00, the equity appears to be in a holding pattern — investors absorbing the strategic signals without rushing to reprice the shares.

That restraint may itself be telling. The Occidental stake, the return to net buying, the resumption of buybacks, and the legal clarity on HomeServices collectively sketch a picture of a company in active transition. Yet the market's muted response suggests that, for now, Berkshire's long-term trajectory matters more to shareholders than any single quarter's maneuvering.
