Checking if an asset exists

[tasruMLT]

I am trying to retrieve a list of assets from my broker and evaluate if they meet certain criteria. However, I have noticed that Yahoo Finance does not always have information on all assets. I have tried using the .info method to determine if an asset exists on Yahoo Finance, but this method is not always reliable. I have also checked if the market capitalization exists or is empty, but this is not always an accurate way to check.

Is there a more reliable method for determining if an asset exists on Yahoo Finance without calling the .info method?

you need a comprehensive list of all US stocks, you can filter them buy exchanges (NASDAQ, SP500, Russell etc)

#402 might help

If you're asking for an alternative call in yfinance, then no 100% reliable method because Yahoo can return nothing if you appear to be spamming. Best option is Ticker.history, least likely to trigger spam (less server load):

try:
  df = yf.Ticker(tkr).history(period="1d", raise_errors=True)
except:
  # Not listed?

Thanks. I will check once encryption issue is sorted out

Encryption doesn't break everything. Price history and fast_info works.
