The gains and losses are different. For example, if you buy a fund with 10 yuan, you can only lose 10 yuan at most, and 20 yuan will lose 20 yuan. The same income is the same. The fund returns of buying 10 yuan will be different from that of 20 yuan, and the returns of 10 yuan will be less.

A fund refers to a certain amount of funds set up for a certain purpose. From the accounting point of view, capital is a narrow concept, which refers to funds with specific purposes and uses. The fund we are talking about mainly refers to the securities investment fund.
