Why is it so difficult to make money in this round of market? Let me summarize a few points for you to see:
1. The rise is fast and short. Basically, it is over by the time you react. It is difficult to intervene in the middle
2. Even if you are in the car when it rises, it is likely that you can't stand it at all, and the holding experience is extremely poor
3. Once the sector switches, if you step on the wrong sector, you will be completely abandoned, and you can't even get the increase of the market
4. There is almost no general rise, it is all rotation
