Transaction price = net fund value on the trading day before the purchase time = 1.452.

Latest price = net fund value on the latest trading day = 1.452 (it will change tomorrow).

Transaction amount = cost price × transaction quantity = 1.452*300=435.6

Cost price = transaction price+transaction cost = 1.452+(5 yuan transfer fees /300 fund) =1.452+0.017 =1.469.

Profit-loss ratio = current price/cost price-1=1.157% ≈1.16%.

Five dollars is a single transaction, transfer fees. 5 yuan if you buy 400 yuan, and 5 yuan if you buy 4 million. The handling fee should be negligible.
