I am trying to get a historical list of the S&P500 underlying stocks mix. all tickers the dates were added to the S&P500 index mix and the dates tickers were removed from the list. and throughout the years for each period what is the mix. I did some search, doesn't seems to have any luck. if anyone can provide some good search keywords, or suggest a place to look for would be appreciated
this is something very specific.
I currently use backtrader to work on some data. if there is a systematic way to get the data, please let me know as well. many thanks.
