How do I access expenseRatio for ETFs

[ntigern]

Hi all,
I am hoping to add expense ratio to the data that I get from yfinance, but am unable to find it populated for ETFs. I forked it and found that if I add fundProfile module in quote.py on the _fetch_info call that it will populate info['feesExpensesInvestment']['annualReportExpenseRatio'].

Am I missing some functionality that will already allow me to access expense ratio for ETFs, or is this the best approach?

The method I updated in my fork:
def _fetch_info(self, proxy): if self._already_fetched: return self._already_fetched = True modules = ['financialData', 'quoteType', 'defaultKeyStatistics', 'assetProfile', 'summaryDetail', 'fundProfile']

You're not missing anything.

Only criticism of your method is it will fetch fundProfile for all tickers not just ETFs, but being smarter requires a lot of work (adding quoteType to cache).

I reported an issue for it today. Just realize that it was discussed previously. Any progress?

Hi @ntigern, following #2041, you are now able to query annualReportExpenseRatio via:

spy = yf.Ticker('SPY')
data = spy.funds_data
data.fund_operations

Attributes	SPY	Category Average
Annual Report Expense Ratio	0.000945	0.007769
Annual Holdings Turnover	0.020000	0.490600
Total Net Assets	308649.800000	308649.800000
