Investors can check their positions, and can intuitively see the position share, position cost, profit and loss, etc. Fund share is the number of funds held by investors. The fund share is determined at the time of purchase and will basically not change in the future. If the fund pays dividends and investors choose to reinvest in dividends, then the fund share will increase.
It should be noted that when redeeming the fund, the share is redeemed, because only the share is confirmed when redeeming, so only part of the share can be redeemed.
