Although short selling -- the practice of selling borrowed shares with the hope of repaying the loan by buying back the shares at a lower price -- goes against the American belief that stocks always go up, I have long been fascinated with it. Short Stories discusses what works, what doesn't, and what some of the leading lights in shorting stocks think about its opportunities and threats. I describe possible short trades and seek your comments and questions for story ideas. I don't offer any investment advice and I don't trade on any of the posts I write.

BusinessWeek reports that the consumer is tapped out. Can you profit from the combination of a falling market and a cash-starved consumer?

I was scheduled to appear this morning on CNBC's Squawk Box to discuss ways to profit from problems with consumer finance. Last night, my appearance was canceled -- I think it might have had something to do with the global market crash. But CNBC's loss can be your gain. Here's why I think the consumer will be the next shoe to drop in the economy and a few ways to profit.

• Unemployment rate rising (to 5% in the most recent report)
• Wage growth slower than inflation
• Declining value of homes makes home equity borrowing a non-option
• Savings rate -0.7% -- the worst since 1929
• Consumer installment borrowing at record $2.46 trillion

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.
