Have a large number of people been trapped in the stock market?

After the stock market starts to rise, some people have to return their investment several times. The first thing to do after returning the investment is to sell it quickly.

Then if you find that it is still rising, do you buy it again?

The same logic as the cryptocurrency circle.

There are not many rich people left.

In short, there must be a group of people who are rich and a group of people who are trapped.
