Buying an open-end fund can make a profit in the following three ways: 1.

The real investment income is the gross profit after deducting the subscription fee and redemption fee when buying a fund. 2. Cash dividend income: According to national laws and regulations and the provisions of the fund contract, the Foundation pays dividends regularly.
