All the money earned by the fund is in the fund account. When a net worth fund is sold, the principal and income are paid together. If there are dividends, cash dividends will be chosen, and dividends will be distributed to investors' accounts in the form of cash. If you choose to reinvest the dividend, the dividend will be reinvested in the Fund. All money funds reinvest in dividends.
The fund profit is similar to the stock profit, but it only needs to be sold to get the income. All the gains seen in the holding process can be called floating earnings.
