Early Life, Education, and First Investments
Warren Buffett was born in Omaha, Nebraska, in 1930. He bought his first stock at age 11 and filed his first tax return at 13. He studied at the University of Nebraska and later earned a master's degree in economics from Columbia Business School, where he studied under Benjamin Graham, the father of value investing. His early career included working at Graham-Newman Corp and later running his own partnership, Buffett Partnership Ltd., which grew capital at a compounded annual rate that outperformed the S&P 500 over multiple decades read more.
Buffett's partnership generated strong returns by focusing on undervalued companies with durable competitive advantages and honest management. He closed the partnership in 1969 and shifted capital into public equities, eventually using Berkshire Hathaway as the main vehicle for his investments. His strategy emphasized buying quality businesses at fair prices and holding them for long periods, a method that built the core of his wealth long before the massive Berkshire conglomerate existed.
Berkshire Hathaway, Major Holdings, and Investment Results
Berkshire Hathaway began as a textile company, but Buffett transformed it into a holding company by acquiring insurance firms such as GEICO and later National Indemnity. These businesses generated large pools of float, which he deployed into long-term equity and fixed-income investments. Key holdings include Apple, which became Berkshire's largest position, as well as major stakes in Coca-Cola, American Express, and Bank of America, all acquired at prices that delivered outsized returns over time SEC filings.
Under Buffett and his partner Charlie Munger, Berkshire compounded book value at a rate that consistently beat the S&P 500 over multiple decades, with only a few down years. The company's annual shareholder letters provide detailed data on acquisitions, write-downs, and operating earnings. Buffett's investment process focused on understanding business fundamentals, management quality, and margin of safety, and he avoided complex financial instruments and speculative trading. His approach turned Berkshire into one of the largest and most valuable companies in the world, with its stock price and book value reflecting decades of disciplined capital allocation strategy details.
Key Companies, Acquisitions, and Current Net Worth
Buffett's wealth comes primarily from his ownership stake in Berkshire Hathaway, which holds billions of dollars in cash, equities, and wholly owned businesses such as BNSF Railway, Berkshire Hathaway Energy, and Precision Castparts. Major acquisitions include the purchase of GEICO in the 1970s and 1990s, the Lubrizol deal in 2011, and the Burlington Northern Santa Fe railroad in 2009, all of which added durable earnings streams. He also made large public-market investments in companies like Apple, Coca-Cola, and American Express, often during periods of market distress, and held these positions for years or decades more on acquisitions.
