Warren Buffett's stock portfolio has half of its capital invested in just 3 companies: which ones and why did he choose them?

Warren Buffett's investment firm, Berkshire Hathaway, reported that nearly half of its declared U.S. equity portfolio was concentrated in just three companies as of June 30, 2026. The major holdings driving this concentration are Apple, American Express, and Coca-Cola. The disclosure highlights the ongoing portfolio strategy of the prominent investor, showcasing a heavy reliance on a select group of established corporations.

The report details both the identities of the chosen enterprises and the strategic weight they carry within the overall portfolio. This high level of concentration reflects Buffett's long-standing preference for anchoring significant capital in a few core, high-performing equities rather than spreading investments broadly across the market.
