As I do at the end of each month, my own list of Liquid Stocks, and my list of Which stocks are in each index? have been updated.
I use the updated list of Liquid Stocks each month for the following few weeks, so that my universe of investment candidates is limited to those 400 or so stocks which are liquid enough (according to my definition) so that I should be able to close a position quickly if I want to.
My lists of stocks in each index is used for reference at a later time – for when I want to know which stocks were in an index, at some time in the past.
