One of my most popular posts over the past year was on S&P 500 Historical Constituents.
Apparently, I am not the only one to have had trouble finding data on the historical constituents of the S&P 500 index. In fact, several readers have even asked me to share a copy of my file with them. Alas, licensing restrictions prevent me from doing so.
Recently, however, one of my readers shared the following website with me: s-p-500.com. It has a list of S&P index changes for 2007, 2008, 2009, 2010 and 2011. If you find other useful websites, please let me know so that I can share them with interested readers.
