The fund profit and loss will show the net value of the fund in the fund account when you redeem it. Funds generally invest in the A-share market. You can judge whether it is profitable or not according to the trend of A shares on that day. Because you can't see the information of each fund's stock position and specific stock investment, you can only roughly judge the fund's income. For example, the A-share Shanghai Composite Index closed at around 1%, so the income of hybrid funds should be around this range.

Transaction price x shares+handling fee = invested capital

Current unit net value x share = current market value

Current market value-invested capital = book floating profit
