The main factor that determines the profitability of a single investment fund is not the quality of the fund.

First of all, the Morningstar rating is only a historical rating, and the future cannot be completely represented by history, because the fund is operated by people, and the level of people will fluctuate, high and low. Fund managers will jump ship and personnel will change. For example, when China's market was five-star, Wang Yawei had already left. The harvest grew by 5 stars, and Shao Jian no longer served.

Secondly, a good fund will lose money if it is not done well, and a bad fund will make money if it is done well. It's a matter of method. Different funds invest in different ways and buy and sell frequently, and the predicted market, like most investors, will eventually lose money. So focus on how you invest in the fund. You can choose the fund with Morningstar. This is no problem. The question is what to do when the fund is selected.
