This report puts all the information one needs to intrepret (or trade) Case Shiller futures traded on the CME. Volume, open interest, graphs of May 31 prices, YTD and MTD price changes are included.

you forgot to say: "housing has bottomed!" and "now is a great time to buy!"

As market-maker I have to be somewhat unbiased. I would say that forward prices have been higher than spot since late 2011,and that the "bottom" has pretty constantly been early-mid 2012. Aslo, buying know means buying today's higher forward prices.
To buy here you don't just need to be bullish, you need to be more bullish than current futures prices. (and opposite for bears.)
My goal is let people know that this contract exists, and hopefully to get the wild bulls and bears to do something (trade) rather than just comment.
