first time posting at Quantitative Finance.
I am trying to use the yfinance python library to load various ETF's data and compared the return.
I understand the adjusted closing price handles the effect of dividend and stock split. I wonder in the case of ETF or mutual fund, does the adjusted closed price takes care of the expense ratio? I tried to Google but got no definite answer.
If not, what is the best way to deal with the effect of expense ratio on return?
