Over on CAPS, some 65% of the 158 members who have rated Dollar Thrifty believe the stock will underperform the S&P 500 going forward. These bears include Chromantix and UltraLong, both of whom are ranked in the top 6% of our community.

Just last week, Chromantix showed skepticism over the stock's recent high-speed price run:

Unemployment has not hit its zenith, nor has home foreclosures, nor interest rates, nor taxes. Yet this rental car company stock goes up 1000% in three months? So people are reportedly skipping air travel and renting cars to take them on vacation instead. That makes perfect financial sense: why pay nothing to take your own car when you can pay two months of car loan for two week's worth of rental? Ugh.

In a pitch from the same day, UltraLong helps string the bear case together:

This company derives 67% of its revenues from Florida, California, Hawaii, Arizona, Texas and Nevada, 5 of the 6 hardest hit states when it comes to housing prices and vacations.

$1,851,500,000 in debt. ... Factor in that whopping 93 million dollars in cash they have with only about 210M in revolving credit available and you have a recipe for disaster, or a massive secondary, you choose your poison. ...

[Dollar Thrifty] is slated to lose roughly 85 cents in 2009 and 19 cents per share in 2010. For a company that is incredibly  dependent on profits to make their debt payments, this doesn't look healthy at all.
