annualReportExpenseRatio missing

yunhongz commented 2 months ago

Describe bug

With over 1100 ETFs traded in NYSE/Nasdaq, I couldn't find the 'annualReportExpenseRatio' value frrom their info records. Is this field no longer available?

import yfinace as yf

ticker='SPYI'

yf_ticker = yf.Ticker(ticker)

info = yf_ticker.get_info()

info.get('annualReportExpenseRatio')

Simple code that reproduces your problem

import yfinace as yf

ticker='SPYI'; yf_ticker = yf.Ticker(ticker); info = yf_ticker.get_info(); info.get('annualReportExpenseRatio')

ticker='QQQ'; yf_ticker = yf.Ticker(ticker); info = yf_ticker.get_info(); info.get('annualReportExpenseRatio')

ticker='SPY'; yf_ticker = yf.Ticker(ticker); info = yf_ticker.get_info(); info.get('annualReportExpenseRatio')

There were multiple efforts to support ETF and Mutual Funds Data. Some efforts were specific to expense ratios (https://github.com/ranaroussi/yfinance/pull/557), or holdings (https://github.com/ranaroussi/yfinance/pull/1872). These efforts also attempted to solve the issues in different methods (i.e. scraping html or using api).

Rather than implementing piece-wise, I think fund level data should be supported holistically as started by https://github.com/ranaroussi/yfinance/pull/1784 using the api method.

I will take this issue and also attempt to resolve the following issues/discussions in one go:

hi @yunhongz, following https://github.com/ranaroussi/yfinance/pull/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
