The objects of the fund include stocks, bonds, currencies and futures.
And each category may have multiple products, such as many stocks, many bonds and so on.
Calculate the value of the day according to the closing price of each product, and all sums are the net value of the fund.
Second, the change of share: people buy (buy) and sell (redeem) every day.
Share of the day = balance of the previous day+subscription amount of the day-redemption amount of the day. (refers to the share, not the amount)
Note: The change of net value will not change the change of share. Purchase, redemption, dividend reinvestment, split and merger will all affect the increase or decrease of share.
You bought 100 copies. There is no re-application, no redemption, and there is no reinvestment, split or merger of dividends. It has always been 100.
