Li Lu reiterates value investing, highlighting six core principles: The first three are directly from Benjamin Graham: 1/ A stock represents a portion of ownership in a business, not just a piece of paper to be traded. Buying stocks is essentially buying a company. 2/ The market is there to serve you, not to guide you. 3/ Investing involves predicting the future, which is inherently unpredictable. Therefore, you should always demand a margin of safety. This helps protect against downside risk and allows for better upside returns. The fourth principle is from Warren Buffett: 4/ Stick to your "circle of competence." You don't need to understand all companies, only to accurately assess those within your circle of competence. The size of your circle of competence isn't important; what matters is clearly knowing its boundaries. The fifth principle is from Charlie Munger: 5/ Go where the fish are. Some markets offer abundant opportunities, allowing for good returns even with average investment skills; others are so competitive that even excellent investors struggle to achieve success. Article 6 is based on Li Lu's own practical experience over the past thirty years: 6/ As a global investor, the essence of wealth is your share (proportion) of global purchasing power, not how much gold, diamonds, or a particular currency you hold. Under the influence of inflation, the purchasing power represented by these things will diminish over time. Buy excellent companies in dynamic countries/markets at favorable prices, hold them long-term, and let your wealth share grow continuously as the company creates value.
