These are two different transactions, that is, the first net value is 1 yuan and the second net value is two yuan.
The amount of each purchase is calculated as 10000 yuan, and the sum of the two purchases is 20000 yuan, which is very simple.
The most important thing is to redeem the share you bought first when redeeming.
Redemption is based on the net value of the day. Redemption must be based on the share with a net value of 1 yuan.
Only the share with a net value of 1 yuan will be redeemed, and the share with a net value of 2 yuan in February will be redeemed.
