MBA Chief Economist Mike Fratantoni said,"Inflation remains stubbornly high, and this trend is convincing markets that rates, including mortgage rates, are going to stay higher for longer." He continued,"Application volume for both purchase and refinances declined over the week and remain well below last year's pace. One notable trend is that the ARM share has reached its highest level for the year at 7.8 percent. Prospective homebuyers are looking for ways to improve affordability, and switching to an ARM is one means of doing that, with ARM rates in the mid-6 percent range for loans with an initial fixed period of 5 years."

The Mortgage Bankers' Association compiles various mortgage loan indexes. The purchase applications index measures applications at mortgage lenders. This is a leading indicator for single-family home sales and housing construction.

This provides a gauge of not only the demand for housing, but economic momentum. People have to be feeling pretty comfortable and confident in their own financial position to buy a house. Furthermore, this narrow piece of data has a powerful multiplier effect through the economy, and therefore across the markets and your investments. By tracking economic data such as the Mortgage Bankers Association purchase applications, investors can gain specific investment ideas as well as broad guidance for managing a portfolio.

Each time the construction of a new home begins, it translates to more construction jobs, and income which will be pumped back into the economy. Once a home is sold, it generates revenues for the home builder and the realtor. It brings a myriad of consumption opportunities for the buyer. Refrigerators, washers, dryers and furniture are just a few items new home buyers might purchase. The economic"ripple effect" can be substantial especially when you think a hundred thousand new households around the country are doing this every month.

Since the economic backdrop is the most pervasive influence on financial markets, housing construction has a direct bearing on stocks, bonds and commodities. In a more specific sense, trends in the MBA purchase applications index carry valuable clues for the stocks of home builders, mortgage lenders and home furnishings companies.
