Todd said it well. This world is filled with various seemingly contradictory theories that are ultimately correct. I call this the 'wave particle duality' of theory. Is light a wave or a particle? Physicists argued for hundreds of years and finally discovered that it depends on how you observe it. The double slit experiment sees waves, and the photoelectric effect sees particles. So both are correct. The investment theory is the same. Duan Yongping doesn't take a glance to the end, only pursuing vague correctness. Buffett said if you don't want to hold for ten years, don't hold for ten minutes. Rakesh said he wants to be a chameleon, both short-term and long-term. If viewed from the perspective of making money, all three theories are 'correct'. Because they each selected an observation framework and then pushed things to the extreme within that framework. The 'light' of the market presents them with laws that conform to that framework. Physics finally solved the wave particle dispute using the principle of complementarity: don't ask what the essence of light is, ask how you interact with it. The principle of complementarity in investment: Don't ask which theory is correct, ask which one you have chosen and whether you have implemented it to the end.
