Do you know what an index is? Once you learn about what they are and how they are constructed you will know your answer.
You already know the high levels?......LOL yeah, OK !! Well then you would already know that the CME runs the show for most index contracts, why dont you ask them ?? http://www.cmegroup.com/ wow,,that was hard wasn't it?
No, I don't think you know the "high levels" because, as the previous posted suggested, if you did you would not have asked ask this question. When you look at SPX Index on your Bloomberg (which I know you have access to), what is that number?
