Berkshire Hathaway Stock Faces Scrutiny Amid Shifts in Apple and Energy Holdings

Berkshire Hathaway’s BRK.B stock has come under renewed scrutiny following recent market movements in its largest holdings. Apple (AAPL), which accounts for roughly 25% of Berkshire’s equity portfolio, has declined 12% over the past three months amid slowing iPhone sales and regulatory headwinds in key markets. Meanwhile, CL=F, the benchmark for crude oil, has fluctuated sharply, impacting Berkshire’s energy exposure, particularly in its holdings of oil and gas service providers. The company’s total equity portfolio, valued at approximately $285 billion as of early 2026, has seen a 6.3% decline in year-to-date returns, lagging behind the S&P 500’s 8.1% gain. Berkshire’s direct stake in Apple exceeds $130 billion, making it the most significant single position in the portfolio. Any sustained weakness in AAPL could significantly affect Berkshire’s overall valuation, especially given its low turnover strategy and long-term investment philosophy. Market analysts note that while Berkshire’s book value per share rose 14% in 2025, the stock’s performance has been stagnant, trading at a 10% discount to its tangible book value. This divergence has fueled speculation about whether the company’s investment approach is adapting to a changing tech and energy landscape. Investors are particularly watching for any shifts in capital allocation, especially in AI infrastructure and renewable energy sectors. The broader financial and technology sectors are reacting cautiously. Shares of other large-cap tech firms have held steady, but investor sentiment toward value-heavy portfolios like Berkshire’s remains mixed. Institutions with large BRK.B positions are reassessing their exposure, while retail investors are monitoring dividend trends and buyback activity for reassurance.
