Before you jump to a conclusion I want to stress the question is about cash index.
I just stumbled upon this page: http://www.cmegroup.com/trading/equity-index/settlement.html
Which says: "On typical days, CME Group begins disseminating index values immediately at 8:30 a.m. Central Time (CT). "
Does this mean CME have their own SP500 calculation? Does this mean they stream it to the users?
If I am not being crazy and the answers are yes/yes... then what data feed re-sells it?
(I was always under impressing that someone 'authorized' by S&P desseminates an 'official' version of it with frequency like 1 tick per 15 sec)...
