In 2006 the Chicago Mercantile Exchange launched it's Housing Futures product. The product was to be based on the S&P/Case-Shiller Home Price Indices developed by Karl E. Case and Robert J. Shiller. There was both fanfair and forecasts for failure. Some thought it would finally allow a popular asset class to have a method of hedging risk. Others believed that it would be traded so lightly that it was basically dead on arrival. While the product has recieved some attention, it is thinly traded and therefor, price discovery is a little fuzzy. While we know that speculators do trade the contract and this is good for liquidity, is it useful as a hedging tool?
I began to research this but in the course of my initial search, found that some academics have looked at this and luckily for my favorite market...Las Vegas! Mark Betrus, Harris Hollans and Steve Swidler perform an analysis of Hedging house price risk using the CME contracts. If you are unfamiliar with hedging concepts, one way to look at it is that you are long whatever you own, so in order to hedge the risk of a price decline of what you own you can use a short position to offset price declines. On that short position you've sold high and bought low and took the difference as a savings against the loss in your long position.
The Betrus et al. study looks at hedging for some typical investors including:
1. Investment groups holding equity stakes in property where returns are from income and appreciation.
2. Mortgage portfolio investors where potential losses may be from increased default rates.
3. Local real estate developers who need to offset price drops while holding inventory.
4. Individual homeowners.
I believe the most useful intances are for the professional investor class. This is because of the size of the contracts which may require too steep of a financial commitment and a margin account. The contract trade unit is $250 times the index value. So for Las Vegas if the index is 134 one would be looking at $33,500. Further, as in my case, I won't even bother to hedge this price decline because the home I am looking to buy is priced to where the monthly payment is cheaper than my rent and I get some more footage and a garage. I also plan to live there for a few years and don't have to put much money down. I really don't care that much about a price decline if it makes financial sense as well as a sense of convenience for me today. I am also not in the habit of forecasting interest rates five years from now and I do know that they are at historically low levels today. For the investor class, I do think this can be a useful tool. It takes a lot of homework though, since each portfolio is different and like every futures and options document says, "past performance is not indicative of future results."
Betrus et al. found that with their sample investment groups and mortgage holders would have reduced house price risk by 88% (except in submarkets where the prices moved idiosycratically from that measured by the index). For builders, it is more difficult to hedge risk because there is weak correlation between new home prices and the index. If they are risk averse, it probably is better to just get the inventory sold to someone either less risk averse or who can carry the product until the market prices rebound, and there are those folks out there. Individuals, if they had cared to hedge, could have hedged significant price risk. Compellingly, the authors also find that hedge ratios were pretty stable over time. So to sum up, in some cases yes, these instruments can provide an effective hedge. The study was published in the Journal of Real Estate Finance and Economics and cound be found at www.springer.com
