In fact, it doesn't matter whether the fund pays dividends or not. If you want to cash out, you can redeem some funds!
After the fund pays dividends, the net value of the fund will drop, because the fund pays dividends by selling its own shares and distributing cash to everyone, so it will drop as much as possible. That is to say, regardless of market fluctuations, the total market value of your fund before and after dividends is the same. For example, the net value of a fund is now 2 yuan, and the net value of the fund will drop to 1 yuan after the dividend per unit.
Funds pay dividends by selling stocks, so when the market is good, being forced to sell stocks will actually reduce the income of investors, so it is not necessarily a fund with more dividends.
