Fund dividend means that the fund company pays a part of the fund income as a dividend to investors. Although dividends are a form of income of the fund, the net value of fund shares may change after dividends, which makes the amount after dividends less than investors' expectations.

First of all, the amount of fund dividends is reduced because dividends are based on the share of each fund. If investors purchase or redeem funds before the dividend date, they will not be able to enjoy dividends. For example, if an investor buys a fund of 1 1,000 yuan before the dividend date, he can only get his share of the dividend, not the dividend amount of the whole fund.

Secondly, the reduction of the amount after fund dividends may also be related to the way of dividends. There are two ways of fund dividend: cash dividend and reinvestment dividend. The former will transfer the dividend cash to the investor's bank account, and the latter will reinvest the dividend in the fund. Although the amount of dividends in the two ways is the same, reinvesting dividends will increase the fund share and make investors actually get less money.

Finally, the reduction of the amount after fund dividends is also affected by the cost of fund management fees. Fund management companies need to deduct management fees, sales expenses and other expenses from the fund, which may have been deducted before dividends. Therefore, investors may get less money after dividends than they actually put in, depending on the specific expenditure of the fund management company.

To sum up, the reduction of the amount after fund dividends is the result of the joint action of many factors. Investors need to know the mechanism of fund dividends and the charging system of fund management companies in order to better evaluate the performance and return of funds.
