1. Buffett’s characteristics: He advocates value investing, which he himself says is 85% Graham and 15% Fisher. It means buying good companies that you understand at reasonable prices and holding them for the long term.

2. Soros’s characteristics: “Reflexivity” theory, which uses the deviation between market expectations and objective “facts” (according to Soros’ theory, there are no strict facts in sociology). When the deviation reaches a critical point It’s time to go long or short.

3. In the eyes of many people, Buffett advocates value investing, while Soros is good at speculation. But Soros's favorite subjects in his life were philosophy and psychology, but he was not sensitive to numbers. However, Lao Ba has been famous for his extraordinary sensitivity to mathematics since he was a child. A twelve-year-old child tried to draw a stock trend chart by himself, which is very surprising. Many people have not noticed that Buffett was born as a stockbroker and has a unique talent for hype and persuasion.
