Over on CAPS, fully 95 of the 490 members who have rated SLM -- some 19% -- believe the stock will underperform the S&P 500 going forward. These bears include cashsage and fmahnke, both of whom are ranked in the top 10% of our community.

Last month, cashsage refused to lend SLM any support: "SLM has one of the most illiquid balance sheets. It is also loss making. Its customers, mostly students, are among the least solvent among the population."

In a pitch from last week, fmahnke also tapped the stock as one that lends itself to trouble:

I'm concerned about the student lending business in general. Although it is difficult to discharge these loans in bankruptcy, they are largely uncollateralized and can be deferred almost indefinitely for a wide variety of circumstances. In a macro economic environment characterized by rising unemployment, I think it could be difficult to collect to these loans. [Sallie Mae] may find that cash flow on these loans may not be as consistent as their schedule debt repayment and preferred stock repayment obligations.
