Warren Buffett's Investment Experience and Philosophy
When we talk about investment gurus, the one name that immediately comes to mind is Warren Buffett. Born in Omaha, Nebraska in 1930, he's known worldwide as the "Oracle of Omaha". As an investment gurus, entrepreneur, billionaire, and philanthropist, he has countless fans who make pilgrimages to the Berkshire Hathaway Annual Meeting every year just to hear him speak.
Buffett's father was a stockbroker and a former member of Congress. Young Buffett developed an interest in investing early on, and everyone around him knew he was a math prodigy. He made his first stock investment at age 11, earning a small profit, and by 13, he had started his own business as a paperboy. In high school, he and a friend invested $25 in secondhand pinball machines and sold them later for $1,200!
Buffett studied business at the University of Pennsylvania and the University of Nebraska before obtaining a master's degree in economics from Columbia University. He continued his studies at the New York Institute of Finance.
After graduation, he worked as an analyst at Graham Newman Corporation, where he learned from Benjamin Graham. In 1956, he founded Buffett Partnership Ltd. in Omaha and gradually accumulated millions of dollars in wealth.
Later, he eyed Berkshire Hathaway, a textile company, and partnered with Charlie Munger to take over control of the company in 1965. They developed it into a diversified investment company that invests in insurance, energy, utilities, transportation, manufacturing, retail, and other assets. It's a tool for Buffett to realize his investment philosophy by acquiring mature but undervalued companies and maintaining a large stake in leading companies.
Once he'd accumulated a lot of wealth, Buffett announced in 2006 that he would donate most of it to charity. 85% of the funds went to the Bill and Melinda Gates Foundation, which focuses on global health issues, American libraries, global schools, and more. Before that, he'd already been involved in charitable work.
In addition to his philanthropic deeds, Buffett also leaves us with valuable lessons. For example: "Invest in a business any fool can run because someday a fool will," "Life is like a snowball, the important thing is finding wet snow and a very long hill," "Rule No. 1: Never lose money. Rule No. 2: Never forget rule number one," "If you aren't willing to own a stock for ten years, don't even think about owning it for ten minutes," and perhaps the most famous one: "Be greedy when others are fearful, and be fearful when others are greedy."

It's worth mentioning that he writes a letter to Berkshire shareholders every year, which is considered a must-read classic in the industry. Robert Hagstrom's book, The Warren Buffett Way, also summarizes Buffett's investment wisdom.
Buffett advocates value investing and seeks investments with controllable risks. He emphasizes a company's intrinsic value (including competitive advantages, financial conditions, management teams, etc.) and avoids investing in companies beyond his scope of expertise. He stresses reasonable prices, safety margins, and long-term investments.
Warren Buffett's Stock Picking Tips
Warren Buffett's investment philosophy provides valuable insights into stock selection strategies.
1. "The Warren Buffett Way," 12 guidelines are summarized in four key areas: enterprise, market, management, and finance.
For enterprises, Buffett looks for simple business models with sustained and stable operations and good long-term prospects.
On the market side, he determines the market value of an enterprise and buys it at a discounted price, using valuation and safety margins to guide his decision.
Regarding management, he values rational, honest, and independent thinking from company leaders.
For the financial aspect, he offers four guidelines:
Buffett advises investors to focus on return on equity (ROE) instead of earnings per share (EPS). Some companies retain profits from the previous year, leading to an increase in EPS. However, ROE measures annual performance better since it represents how much net profit is generated by one unit of net assets. Companies with higher ROE are more efficient at generating profits with their available resources and are often better investments.
He suggests calculating True Economic Earnings (TEE), which is free cash flow obtained by adding depreciation, depletion, and amortization to net income and then subtracting capital expenditures. Companies that generate more cash than they consume are preferred.
Buffett emphasizes high-profit margins as critical indicators of management capabilities and cost control abilities.
For retained earnings, he believes that every dollar should create at least one dollar of market value. If a company's retained earnings over the past ten years add up to X, and the increase in market value over the same period is Y, if Y is less than X, it means the company has not effectively used its retained earnings and has regressed.
2. In his 1977 letter to shareholders, Buffett identified four key principles for stock selection: investing in businesses that have straightforward and predictable operations, good long-term prospects, are managed by ethical and competent executives, and can be purchased at an attractive price. These principles align with the guidelines described above, covering enterprise, market, and management aspects.
3. In his 1987 letter to shareholders, Buffett emphasized the importance of return on equity (ROE) as a critical investment criterion. He specified two conditions that a good investment should meet: first, the average ROE must exceed 20% over the past ten years; second, no year's ROE should fall below 15% during this period.
4. Buffett has repeatedly stressed the importance of gross profit margin, which is calculated as gross profit divided by revenue. In public forums, he has recommended companies maintain a high gross profit margin of at least 40%. Among Berkshire Hathaway's long-term holdings, many companies have met or exceeded this benchmark.
5. Debt-to-equity ratio is another metric that Buffett considers when making investment decisions. Companies that carry excessive debt may be too aggressive and carry higher risks for investors.
