As interest rates on payday loans keep getting higher, World Acceptance Corp's (WRLD) stock price looks like it is ready to do the same.

World Acceptance -- a major player in the payday loan industry in both the southern United States and Mexico -- just broke up and out of a bullish continuation pattern on its stock chart.

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
