The dividend payment time of each fund is uncertain. Some funds may not pay dividends for one or two years, depending on whether the fund manager decides whether they can pay dividends. Dividend is to distribute part of the income to fund investors in cash, which is originally a part of the net value of the fund unit. Therefore, investors actually get the assets on their books, which is why the net value of fund shares fell on the day of dividends (ex-dividend date).
Dividends are not as much as possible. Investors should choose a dividend distribution method that suits their own needs. Fund dividend is not the biggest standard to measure fund performance. The biggest criterion to measure the fund's performance is the growth of the fund's net value, and dividends are just the cash for the growth of the fund's net value.
