No, the fund shares are calculated based on the amount at the time of purchase. The rise or fall of the fund will not change the fund shares. Subsequent purchases of the fund or fund dividend investors choose to reinvest the dividends. Then the fund shares will change.
The fund implements T+1 trading, and transactions are based on the net value of the fund. Each transaction is calculated based on the net value of the fund at the close of the day (there is only one transaction price on a trading day), and the second one is purchased on the same day. The share is confirmed on the trading day.
