Berkshire's Portfolio to Focus on Stability and Diversification?

Berkshire Hathaway is strategically rebalancing its investment portfolio, divesting its 17-year stake in Chinese EV maker BYD and reducing holdings in Apple and Bank of America to mitigate concentration risk and exposure to geopolitical uncertainties. Concurrently, Berkshire has increased its investments in Japanese trading houses, including Mitsubishi and Mitsui, citing attractive valuations and improved corporate governance. These moves underscore a broader strategy to enhance portfolio stability, geographic diversification, and ensure robust cash flow generation for future capital allocation.

Analysis

Berkshire Hathaway is executing a significant portfolio rebalancing focused on de-risking and geographic diversification. The firm has fully exited its 17-year investment in Chinese EV manufacturer BYD, a move likely driven by concerns over geopolitical uncertainty and intensifying competition within China's EV market. Concurrently, Berkshire has reduced its concentrated holdings in Apple and Bank of America, signaling a deliberate strategy to mitigate single-stock risk. This capital is being redeployed internationally, with increased stakes in Japanese trading houses such as Mitsubishi Corp. and Mitsui Corp. This pivot is predicated on Japan's corporate governance reforms, which have improved capital efficiency, and the relatively modest valuations of Japanese equities compared to their U.S. counterparts. Despite these strategic shifts, which have contributed to a 9% year-to-date share price gain outperforming the industry, cautionary signals exist. The stock trades at a price-to-book ratio of 1.59, above the industry average of 1.54, and carries a Zacks Value Score of 'D'. Furthermore, consensus EPS estimates for 2025 and 2026 have been revised downward by 2.5% and 2.3% respectively, with 2025 EPS projected to decline year-over-year before a potential recovery in 2026.

Key Decisions for Investors

• Investors in BRK.B should view the portfolio rotation as a strategic shift towards stability and lower geopolitical risk, but must weigh this against the challenge of replacing the high-growth contributions from its former concentrated positions.
• Given BRK.B's premium valuation at a 1.59 price-to-book ratio and recent downward revisions to 2025-2026 EPS estimates, it may be prudent to monitor for a more attractive entry point or evidence that new investments can offset near-term earnings pressure.
• Berkshire's full divestment from BYD serves as a significant bearish signal for the Chinese automaker, highlighting concerns from a long-term, influential investor about competitive and geopolitical headwinds.
• The increased allocation to Japanese equities like Mitsubishi and Mitsui validates the investment thesis around Japan's governance reforms and attractive valuations, suggesting investors could explore this market for diversification opportunities.
