Those who are excited about the fundamentals say that the A-shares have exceeded 4100 points. In fact, raising the A-shares is to keep the system alive longer, not to make all participants profit. Relatively smart ordinary investors can make money in the A-shares easily. Wanting to make more money is difficult. The system will tell you which money is for making you profit and which money you are contributing to the system. Before the system turns hostile, it depends on how quickly you can run. But before fools come in on a large scale, we still have to wait a bit before the system turns hostile.
