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.

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.
