efficiently download info for multiple symbols

yf.download downloads only prices and it has a threads option making the download very fast.

However, if I want to download info for multiple symbols, I have to use Tickers and when I loop through the results it seems to be downloading the entire API results (inc prices), which is very slow and there is no parallelization option.

minimal example:

import yfinance as yf
def __filter_dict(bigdict, sub_key):
  return {k: bigdict.get(k, None) for k in sub_key}

fields = ['symbol', 'quoteType', 'shortName', 'longName', 'annualReportExpenseRatio']
ticker_list = ['QQQ', 'SPY']
tickers = yf.Tickers(ticker_list)

tickers_items = tickers.tickers.items()
list_dict = [__filter_dict(value.info, fields)  for key, value in tickers_items]

The loop for key, value in tickers_items is triggering a full download of all the assets in tickers_items, inc prices, which I am downloading using yf.download in a different place.

Any ideas on how to improve the efficiency and speed of this?

thanks
