The registration date of fund dividend rights and interests is the date that the fund company needs to set when distributing dividends, and it is clear which fund holders can participate in dividends. Set the date as the rights registration date. In other words, investors who still hold or buy funds in date of record and are confirmed can enjoy this bonus. The date determined in the bonus plan to deduct the bonus from the fund assets. On the ex-dividend date, the net value of the fund will decrease. If we don't consider the market fluctuation of the day, what is reduced is the cash dividend of the unit fund. Dividend day is also the day when fund dividends are distributed to fund holders. There is no necessary connection between evaluating the quality of the fund and the amount of dividends. Make a reasonable judgment according to the actual market situation!
