Historical data on index constituents

Hi there. I'm trying to find a (hopefully free) source of historical data for constituents of major indexes, primarily S&P 100, 400, 500, 600, 900, 1500. I know I can get the latest from S&P site itself, however I need to know what was in those indices at a particular time in the past (for at least the past year, although further back in time would be great).

Does anyone know where I might obtain this information? Or maybe someone has kept track and would be kind enough to share?

Thanks in advance.

 

my experience has been that s&p does not offer this data for free. If you wanted to engage in a lot of labor, check out an index mutual fund and pull the holdings out of the prospectus.

How far back do you need it?

 

I'm hoping for at least a year, but if you happen to have it available for the last 3 months that would work. Thanks

 

Ideally for at least a year, but if you happen to have it for 3 months that may work.

Register (it's free) and login at:

Then go to the tab "US", at the bottom you can download excel files for the constituents of all these indices you mentioned for each day of the last year.
