Warren Buffett is arguably one of the most successful investors of all time. Over the years, he has developed a set of principles and strategies over his career. He was inspired by the teachings of key financial thinkers like Phil Fisher, Benjamin Graham and Charlie Munger.
Key Influences Phil Fisher Fisher’s approach focusses on quality companies with long-term growth potential, emphasizing focused portfolios and long-term holdings. He believed in gathering information about a company beyond what’s readily available. His lessons on maintaining a focused portfolio and committing to long-term holdings are clear influences on Buffett’s patient, value-driven investment philosophy.
Benjamin Graham Known as the father of value investing, Graham’s core principle was to buy stocks at a price lower than their intrinsic value, creating a margin of safety (MOS). This strategy helps mitigate risk and increase the likelihood of future gains. Buffett absorbed Graham’s teaching on finding stocks that are undervalued and buying them at the right price— definitely a large contributor of his investment success.
Charlie Munger Munger is Warren Buffett’s long-time business partner. He introduced the concept of economic moats, which refers to a company’s long-term, sustainable competitive advantages. Munger advocates investing in businesses that can fend off competition and maintain profitability over time. This philosophy drives Buffett’s focus on companies with strong market positions and solid long-term potential, favoring these over shorter-term, speculative opportunities.
Buffett's Investment Approach 1 - Buy for the Long Term. Buffett’s strategy emphasizes identifying companies that can consistently perform well over long periods. He holds stocks for years, or even decades, often looking for opportunities where other investors may overlook value.
2 - Buy at the Right Price. Buffett is known for his discipline in waiting for the right moment to invest. His approach ensures he doesn’t overpay, instead seeking stocks when they are priced below their true value, maintaining a margin of safety.
3 - Buy the Right Stocks. Buffett doesn’t just buy cheap stocks, he buys quality companies with sustainable advantages. His goal is to invest in firms with strong business models that will continue to perform well regardless of market conditions.
Warren Buffett emphasizes investing in companies with simple and clear business models, ones that fall within his circle of competence. He prefers to thoroughly understand the operations, products, and long-term prospects of a company before making any investment. This principle is combined with in-depth analysis of how the company operates and how sustainable its valuations and future growth prospects are. If a business model is too complex or outside his expertise, he avoids it.
He prioritizes companies with integrity and transparency in their management. He believes in backing leaders who are passionate, have strong vision and execution capabilities and who use shareholder funds wisely. Trusting management to run the company effectively, with efficiency and accountability, is critical for long-term success in Buffett’s eyes.
Investing in quality companies isn’t enough—Buffett also insists on buying them at attractive prices. He maintains a strict discipline of buying with a margin of safety, ensuring the price paid is lower than the company’s intrinsic value. This means waiting for opportunities to buy great businesses at fair prices rather than settling for fair businesses at attractive prices, which may not perform well over time.
Buffett has made many of his lessons and strategies available to the public through his letters to shareholders and partnership letters. These documents offer insight into his investment approach, decision-making process, and lessons from both successes and failures.
