Morningstar has a five-star rating, indicating that the recent data are all better. This fund may be underestimated, or it may have good growth, but it does not mean that it can be bought immediately. Investors should also look at the rating time and combine their own logical analysis to buy. Because some funds are in an undervalued period, the market outlook may continue to consolidate, so if you don't have patience after buying, it may be counterproductive. But for long-term investors, you can buy appropriately.

In terms of star rating of Tian Tian Fund Network, the software rating agencies include China Merchants Securities, Shanghai Securities and Ji 'an Jin Xin. If you are rated as five stars by these three institutions, you can buy some appropriately.
