Are Shiller real-estate futures and options catching on with investors?
The Case-Schiller macro derivatives market has seen very minimal activity.  For example, in the  three regional markets of San Diego (SDG), Boston (BOS) and Los Angeles (LAX) on 28 November 2011, there was zero trading volume, no trades settled, no open interest.  * Source: CME Futures and options activity[PDF] for all 20 regional indices.  Why haven't these real-estate futures caught on with investors?  Keep in mind that the CME introduced these indices, with support from Professor Shiller and partner Standard & Poor's several years ago. The CME seems committed to wait this out, as they have shown no indication of dropping the Case-Shiller indices. There are alternative real-estate investment securities to the Case-Shiller indices.  I don't think the market of investors is so small that Case-Shiller has been, in effect, "crowded out" by them. I think it is more likely a matter of known quantities. Also, I don't know how well these alternatives are doing! Additional reference: CME spec's for Case-Shiller index futures and options contracts.
