Warren Buffett's Investment Philosophy at Berkshire Hathaway

Warren Buffett employs a strategy known as "value investing," seeking companies where the stock price is below the estimated intrinsic value. The philosophy is built on patience, long-term holding, and a preference for businesses with sustainable competitive advantages (the "moats"). The fund favors sectors where it perceives the ability to generate stable cash flows, including financial services, consumer goods, information technology, and energy. Historically, Berkshire Hathaway's performance has been significantly driven by a combination of public equity investments and private stakes, with decades of outperformance against market averages, though this filing details only public positions.

Cuts and Exits - What Buffett is Leaving Behind

Based on information from the August 14, 2026, 13F-HR filing, the report does not indicate any reductions or complete exits from holdings. Without explicit mentions, we cannot conclude on any disengagement by Berkshire Hathaway from its existing positions. The document only presents the portfolio composition as of the quarter's last day, without indicating percentage or volume changes from previous filings.

Limitations of the 13F: What This Filing Doesn't Say

Required by the Securities and Exchange Commission (SEC), the Form 13F must be filed within 45 days after each quarter's end. It only covers long positions (held shares) and excludes short sales, options, futures contracts, and foreign investments. Additionally, the filing does not reveal purchase prices, acquisition dates, hedging strategies, or indirect holdings through funds or affiliated entities. Thus, even though the reported portfolio totals $299.3 billion, its actual value may differ due to unreported assets or derivatives. Individual investors should interpret these data as a partial snapshot of Berkshire Hathaway's exposure, not an exhaustive view of its global strategy.
