Cash Shiller Home Index has futures just like the S&P 500. According to the futures the index for the 10 metro areas is expected to be flat, basically stay at the same value until 2014. So, I think it's a little interesting that Karl Case says it's a great time to buy. Didn't he look up the futures on this own index?
I pasted the index here just in case I got it and some one could correct me.
