His methods have become legendary, and his fortune was built on careful planning, iron discipline and sound decision-making.

His fortune, estimated at around $147 billion in early 2026 (Bloomberg Billionaires Index), still places him among the eleven largest fortunes in the world.
Warren Buffett: The Story of an Exceptional Investor
Warren Buffett’s path to success began in childhood. Born in Omaha, Nebraska, in 1930, he grew up in a middle-class family. Buffett started his investing career at the age of 11, buying his first shares with money he had earned delivering newspapers. Despite his family’s modest means, Buffett was an excellent student and finished high school at 16. He then attended the University of Nebraska-Lincoln, where he studied business and economics before continuing his studies at Columbia Business School, where he studied under Benjamin Graham, regarded as the “father of fundamental analysis.”
After graduating, Buffett worked as a financial analyst in New York before returning to his hometown of Omaha, Nebraska, to found his own investment firm, Buffett Partnership Ltd, at the age of 26. In 1965, he bought the textile company Berkshire Hathaway, which became the foundation of his financial empire. Turned into a holding company, it began generating impressive returns almost immediately.
He is notably known for having played an active part in the history of the New York Stock Exchange (NYSE) and for becoming one of the first self-made American billionaires.
Contrary to popular belief, Warren Buffett has never written a book. His reference writings are the annual letters to Berkshire Hathaway shareholders, penned every year for decades and studied around the world as a true investing manual. The collection “The Essays of Warren Buffett”, compiled by legal scholar Lawrence Cunningham, gathers and organizes these letters by theme: it is the most accessible gateway to his thinking.
Warren Buffett’s Investment Philosophy: Value Investing
Buffett’s success quickly caught the attention of other investors, and he became a highly sought-after investment advisor. His method relies on a combination of fundamental analysis and value investing, allowing him to generate exceptional returns year after year.
Warren Buffett’s investment philosophy is often described as “value investing”: it consists of buying stocks that are undervalued relative to their fundamental value. He strives to understand the companies he invests in by meticulously studying their financial statements and meeting their executives. He looks for companies with a durable competitive advantage (the famous “moat”) and solid management. Buffett’s premise is that the stock market is a collection of individual businesses, not just an index to speculate on: you have to look beyond the market noise and focus on each company’s fundamentals.
Buffett is also known for his “buy and hold” strategy — in other words, long-term portfolio management. Instead of focusing on short-term market trends, he prefers to invest in companies he believes are undervalued over the long run. This approach stands in stark contrast to day trading and scalping, which he has often criticized. He has also been skeptical of active management, arguing that few investors manage to beat the market over the long term.
Buffett also attaches great importance to compound interest, which involves reinvesting investment income to generate exponential returns over time. He sees compounding as the key to long-term wealth creation, and he has applied this approach with resounding success. This compounding logic can also be found in modern strategies such as the dollar-cost averaging (DCA) strategy, particularly popular among long-term investors.
Finally, Buffett applies a disciplined, concentrated approach. He avoids investing in companies he does not understand — a golden rule he calls his “circle of competence” — and takes the time to do thorough research before every decision. He favors rigorous risk management: a portfolio diversified in a reasoned way, but with meaningful positions in his strongest convictions, and constant attention to cash flow as well as recurring, predictable earnings.

Furthermore, Buffett’s success has underscored the importance of adopting a long-term view.
