SSE rating is a rating index issued by Shanghai Stock Exchange, and China Merchants Rating is a rating index issued by China Merchants Securities.

Shanghai stock exchange rating and investment promotion rating are authoritative in the industry, and all of them will give star ratings according to the performance of funds in all aspects. It's a bit like tourist attractions will be divided into 5A-level scenic spots, 4A-level scenic spots, 3A-level scenic spots, etc. The higher the level, the better the quality of tourist areas. The same is true for funds. The higher the economy, the better the past performance. Ordinary investors are lack of professionalism and limited experience, so they can use these professional rating agencies to find funds with higher fund ratings.
