Recently the company behind the S&P Indices (S&P Dow Jones) has decided to withdraw their constituent data from the Capital IQ Compustat databases. This means that it is still possible to get the prices for the overall indices, but it no longer is possible to get detailed data on individual companies as they move in and out of the lists over the years. Lists like S&P 500 are heavily used in much research as a benchmark list for market developments.
I know of only one database (available to me) at the university that still allows for the generation of constituent lists at the Vrije Universiteit Amsterdam and this is the database FactSet. There is one drawback compared to the lists that used to be available through Compustat, however: where Compustat made it possible to generate a multiyear list over time, FactSet only allows you to generate a daily list.
If you need multiyear lists from FactSet you will have to download multiple lists for years and then combine them yourself.
I have created an example movie on how to download an index list and put it on Youtube:
Using FactSet requires FactSet software as well as a FactSet account. Information on this for personnel and students at the university is available here.
N.B.: The Compustat database Execucomp has annual data on executives for companies that are (or have been) part of the S&P 1500 list. A download of company codes (GVKEY, CUSIP, Ticker) could perhaps serve as a rough list on which companies are part of the index over a time period. It is only a rough estimate, as the data is based on annual SEC filings and the index changes daily. Execucomp includes data going back to 1992.
