Changes in S&P 500 components

July 12th, 2021, 9:10 pm

This has probably been asked before; however, I cannot find a close answer.

QUEST:  I would like a list of the historical changes to the S&P 500 components (I do not care about the cap-weights) since 1960.
  symbol, company name, date change announced, and effective change date, action (added / removed / merged / name or symbol change)

caution:  a purchased data set (limited to the last 10 years) is in conflict with a common "*wiki*" web-site
               and both of the above reconcile only irregularly and inconsistently with a third frequently referenced list
               finally, a popular and expen$ive US based financial analytics / data platform: 1) is limited to a relatively short recent time frame  2) does not reconcile completely against any of the first three

any assistance is greatly appreciated

Have no idea how reliable, but there is a link here from 1957, the year the modern index (500 stocks) started.

The definitive source is, of course, the index maintainer -- I guess S&P Global.
