Beginner question regarding P/L for an ETF I bought.?

I believe SCB includes the selling commission in their P/L figure. So meaning your gain has to be cover the commission before it is considered as profit.

It might be because of the broker fees. Or might be because of the currency loss. Some broker will take into account the current currency exchange rates and show your P/L. You can check with your broker to clarify.

Example, I invest in a US ETF, the ETF gain 2% over a period of time. During the same period, USD depreciates 4%. In this case, my brokerage account will likely show a loss (In terms of SGD).
