The most important thing in choosing a fund, regardless of whether it is new or old, is to choose a fund manager and see how the fund manager's past historical performance and management ability are. How to look at the fund manager? Jiafeng Reid analyst said that the easiest way to see whether the top fund managers with long-term stability have him/her shows that the performance is ok. In addition to paying attention to the old funds they have issued, they can also pay attention to the new funds they have issued, but we should also know whether he is only in name only and does not directly participate in fund management. If so, we should be cautious. For the purchase of stock funds, there is no final conclusion about which is better for the old and new funds.
