The unit of a fund usually refers to the fund share, which is the smallest trading unit of the fund product. The fund company will divide the fund assets into several shares according to a certain proportion, and the value of each share is the same. When an investor buys a fund, it is equivalent to buying a certain number of fund shares, and the total number of shares held by investors is the size of the fund.

The unit of the fund can also refer to the net value of the fund. Net value refers to the total assets corresponding to the fund shares divided by the total number of fund shares, that is, the value of each accounting. The net value is usually a direct reflection of the growth of fund scale or the change of asset value, while the fund share is the embodiment of investors' holding of fund rights and interests.

For investors, it is very important to know the fund unit. First of all, investors can buy fund products through fund shares and enjoy the corresponding income according to their shares. Secondly, investors can also understand the performance and value changes of fund products through the net value of funds. Finally, investors need to choose appropriate fund products and investment schemes according to their investment needs and risk tolerance.
