Some people say that the leading stocks in the U.S. market decades ago eventually fell out of favor. For example, the former 'Nifty Fifty' like IBM, Kodak, and other giants. If you keep betting on the leaders today, tomorrow's leading tech companies might also decline. Times have changed, and you can't apply the past to the present. The biggest difference is that the old giants like IBM, Kodak, and Nokia were selling hardware. With the continuous advancement of technology, new innovations brought massive disruptions to them. Today's giants, like Apple, Microsoft, Google, Facebook, Amazon, and Tencent, are platform-level companies. Overturning a platform might be harder than overthrowing a country. As long as they don't make countless strategic mistakes, you could say these companies are at the level of human civilization enterprises. They will only grow bigger and stronger in the future. When new technologies emerge, they are the first and largest players to invest heavily. AI, biotech, autonomous driving, robotics, etc.—they're all betting big and making strategic layouts. How could they possibly decline???
