Day Trading With House Prices
BOSTON (MarketWatch) — The Chicago Mercantile Exchange is the latest futures and options market to offer contracts based on home values, hoping to capitalize as jittery homeowners attempt to protect against price declines and large investors look for more direct ways to participate in the $20 trillion U.S. housing market.
"The housing boom of the past few years has been unprecedented," said Shiller, a Yale economics professor and noted voice on speculative bubbles."We need a liquid market for investors to take positions in home prices," he added in a recent conference call, sponsored by Institutional Investor magazine, on the new financial products. The futures and options can be used by those nervous about a potential pullback in the value of their homes as the housing market stumbles or by investors who want to speculate on the future direction of prices. "Protection against a loss in the value of one’s home is the big draw of these products," said Shiller, who noted recent polls show about one-third of Americans think the U.S. is in a housing bubble. "There is vulnerability in a lot of cities where home prices have boomed a lot more than rents or construction costs," Shiller said. Still, forecasting home prices is notoriously dicey for economists because home values aren’t explained well by fundamentals such as building costs, population and interest rates.
The indexes behind the CME housing derivatives use a repeat-sales technique that attempts to minimize the effect of the mix of homes being bought and sold. For example, larger homes are typically purchased in the summer months, giving the appearance of rising home prices, Shiller said. Additionally, there are changing preferences for homes or condominiums which can also distort the averages, and home improvements also need to be factored in. "Our approach tracks the price of individual homes that have been resold, so if the index goes up 5%, it’s because a house was sold and sold again for 5% more," Shiller explained.
How they work
The Chicago Merc introduced cash-settled futures and options based on housing markets in Boston, Chicago, Denver, Las Vegas, Los Angeles, Miami, New York, San Diego, San Francisco and Washington, as well as a weighted composite index.
The contracts are priced by multiplying the index value by $250; the average contract size for the various cities is roughly $55,000, although they vary by region, according to Sayee Srinivasan, associate director of research and product development at the CME. He said the exchange is considering adding contracts for other booming real-estate markets such as Phoenix and Orlando.
"The futures markets like volatility, so the contracts based on the most volatile housing markets might see the most volume," Srinivasan said.
For each region, there are four contracts, which expire on a quarterly basis, so there are currently contracts for August 2006, November 2006, February 2007 and May 2007.
Although the contracts have only been trading for a very short period, most of the interest is looking further out on the curve with the May 2007 contracts getting the most action initially, said Fritz Siebel, senior broker at Traditional Financial Services Inc. There could be demand for longer-dated contracts, something the CME is considering if the existing contracts prove popular enough. Siebel noted the early interest has been in derivatives based on hot West Coast markets in San Diego, Los Angeles and Las Vegas, and also Miami on the East Coast.
