Serving the "underbanked" segment of society has become big business and the leading firms in the group are in expansion mode. One of the biggest such companies runs the largest network of outlets in Canada and the U.K. and the second largest in the U.S.

Dollar Financial Corporation (NASDAQ: DLLR) operates nearly 1,300 financially-oriented service stores. Its customers are typically low to moderate income service sector earners, who don't use, or have access to banks. Services include check cashing, short-term consumer loans, money order/transfer products, reloadable debit cards, electronic tax filing, and bill payment services. Legal document processing is available in over 100 outlets. The company launched an Internet-based payday loan product in California last month and now intends to expand the offering to additional states.

Dollar Financial pleased investors last week, when it reported fiscal Q4 EPS of 48 cents and revenues of $109.1 million. Analysts had been looking for 47 cents and $107.2 million. In discussing the better-than-expected numbers, the CEO particularly noted the positive effects of the firm's expansion into new areas of the U.S. and also commented on solid revenue increases in Canada and the U.K. Further, management offered in-line guidance for FY08 results.

Credit card debt has been soaring since the home equity loan market dried up, according to MacroMavens (subscription required). Leading companies in this space include America Advance (NYSE:AEA), Cash America (NYSE:CSH), Dollar Financial (NASDAQ:DLLR), EZCORP (NASDAQ:EZPW) and ACE Cash (NYSE:ACE). Many have seen revenues jump 50% during the past three years but could now be headed for trouble.

While credit card debt has been increasing, home equity loans have been declining and lending terms have become much more stringent, thereby reducing the risk exposure for these companies.

In the Alan Abelson Barron's column (subscription required) this past weekend, MacroMavens suggested shorting the subprime credit card companies and going long Fannie Mae (NYSE:FNM). MacroMavens also suggested shorting regional banks and mortgage brokers.
