Warren Buffett
Warren Buffett has run Berkshire Hathaway since 1965, building it from a failing textile mill into one of the world's largest holding companies. His approach is patient, concentrated value investing — buy great businesses at fair prices and hold them for decades. Berkshire's public equity book is unusually concentrated, with a handful of large positions (led for years by a giant Apple stake alongside financials, energy, and consumer staples) accounting for most of the portfolio.

Buffett is the most-studied investor alive, and his quarterly 13F is scrutinized worldwide the moment it files. New or expanded Berkshire positions move the stocks involved because the market reads them as a decades-tested vote of confidence.
