After adding positions, the total purchase amount increases, which is equivalent to the denominator increase, but the income will not increase immediately, and the yield will decrease, but the income will not be affected.

When the fund is sold, the redemption fee shall be calculated in proportion to the holding time of the fund, that is, the holding days of the fund shall be calculated from the confirmation date of the fund subscription to the day before the confirmation date of the fund sale. For example, the original 100 copy (held for more than 7 days) plus 50 copies (not more than 7 days), then when selling 50 copies, this part will be counted as more than 7 days, following the principle of first in, first out.

No matter when the fund is purchased, the net redemption value of the fund is calculated according to the net redemption value of the trading day, regardless of the purchase time of the fund. If redemption is applied before May 22nd 15: 00, the net redemption value of the fund will be calculated according to the net redemption value on May 2nd1day.

Therefore, the earlier the fund is bought, the longer it is held, and the redemption rate will be relatively lower. At the same time, the fund shares purchased on the same day cannot be sold on the same day, and can only be sold after the fund purchase is confirmed.

If a fund sells a part of its position after adding a position, its profit will be shared equally with the remaining share, thus reducing its position cost. On the contrary, selling a part at a loss will increase its position cost.
