Why is it so difficult to make money in this round of market?

1. First of all, the rise is very fast and the time is very short. Basically, before you can react, the rise has already ended, and it is difficult to get on the train in the middle.

2. Even if you catch up with the train, you will probably have to endure a very poor holding experience until you can't help but want to sell it.

3. Once the sector switches, you will be completely thrown away if you step on the wrong sector, and you can't even get the increase of the market.

4. Basically, there is no general rise, and each sector rises in turn. It is difficult to catch up if you miss it.
