Early Career and First Investments
Warren Buffett began investing as a child and built a paper route, later studying value investing under Benjamin Graham at Columbia Business School. By the mid 1950s he started Buffett Partnership Ltd., pooling capital from family and friends to buy undervalued stocks, and the partnership compounded money at strong annual rates before he shifted focus to public equities and private businesses. His early partnership returns are documented by sources like Forbes.
Buffett closed the partnership in the late 1960s and took over Berkshire Hathaway, a textile company, turning it into a diversified holding company that acquired insurance firms, railroads, and consumer brands. He focused on businesses with durable competitive advantages, strong management, and predictable cash flows, and he kept most of Berkshire's earnings reinvested rather than paying large dividends, which allowed compounding to accelerate over decades.
Core Investment Strategy and Key Holdings
Value Investing Principles
Buffett follows a disciplined value investing approach, seeking companies trading below intrinsic value with high return on equity, low debt, and consistent earnings. He prefers businesses he understands, such as consumer brands and financial institutions, and he holds shares for years or decades, avoiding speculation and short term trading. His partnership letters and Berkshire annual reports explain this framework in detail.
Major Investments and Companies
Buffett built large positions in Coca-Cola, American Express, and Apple, and Berkshire owns BNSF Railway, GEICO, and Dairy Queen. He also invested in companies like See's Candies and Precision Castparts, and more recently he increased stakes in Apple and other tech firms, showing a willingness to adapt while sticking to core principles of margin of safety and long term ownership.
Wealth, Ranking, and Legacy
Net Worth and Global Rankings
Warren Buffett has remained among the richest people in the world for decades, with his net worth driven mainly by Berkshire Hathaway shares and reinvested gains.

He continues to oversee Berkshire's strategy, make acquisitions, and share insights through annual shareholder letters and public interviews, cementing his role as one of the most influential investors in modern finance. His approach is studied by investors worldwide, and his career shows how patient, research driven investing can build lasting wealth.
