Stock return: Look at your buying cost price. The difference between the purchase cost price and the current price multiplied by the number of shares is the profit (loss). This is relatively rough, and there are transaction fees for stock trading, but it is relatively small and can be ignored.

Fund income depends on the net value of the fund when you buy it. The current net value of the fund MINUS the net value of the fund when you bought it multiplied by the fund share is the gain (loss).
