Hello,

I'm building a study on long-term winners vs. losers and need full daily OHLCV history including companies that no longer trade. yfinance covers the survivors very well (Nokia, BlackBerry, Intel, GE, Xerox), but unfortunately drops the fully delisted names - which are exactly the ones I need for my study:
* Yahoo (AABA / YHOO)
* AOL
* Sears Holdings (SHLDQ)
* Blockbuster (BBI)
* old Eastman Kodak pre-2012 bankruptcy (EK / EKDKQ — yfinance only has the post-2013 KODK)
Where do you guys pull delisting survivorship-bias-free daily history? I am looking for split/dividend-adjusted data, ideally free or low-cost if possible -

I have heard of Stooq, Norgate, CRSP, Sharadar/Nasdaq Data Link but I do not have too much experience with these services. I found one provider but this datafeed is $3500/month which seems a bit too expensive for me..

What actually works for delisted tickers in practice for you? Any API or bulk source appreciated.
Any tips are welcome. Thanks a lot!
