A rise in jobless claims was trumped by a housing number that was not so bad. There was also a rise in oil prices after NOAA released the path of Tropical Depression Three, revealing that it could be a threat to the Gulf of Mexico oil infrastructure. Regardless of the market move, this was another light-volume trading day. Ben Bernanke's testimony acted as a wash between yesterday and today because his lack of growth stance yesterday was negated today with more certain comments about new tools for the FOMC to use to counter a slowdown.

Leucadia National (NYSE: LUK) is a holding company that has been compared favorably to a young Berkshire Hathaway (NYSE: BRK.A), and BloggingStocks' Aaron Katsman has suggested that company as a good alternative to Berkshire for investors.

Apparently Leucadia has also taken Buffett mentor Benjamin Graham's mantra to heart: "Be fearful when others are greedy and greedy when other are fearful."

Leucadia has boosted its stake in AmeriCredit (NYSE: ACF) all the way up to 22.4%. It's hard to think of a more contrarian investment in light of the consumer credit crunch: AmeriCredit buys auto loans from dealerships and makes its own loans through its dealership network -- 80% of the loans are for used cars.

Fears of a continuing rise in defaults have sent shares of the company down big over the past year. The stock is currently trading at a low P/E and a discount to book value. The big question is whether all the bad news is priced -- it's possible that the company will have to take additional losses on bad loans, just as many subprime housing lenders have.

Analyst summaries provided by TheFlyOnTheWall.com (subscription required).

If the American economy tanks, look for car loans to follow the same pattern as house loans, right into the dumpster. However, Sekurus Inc. may have a tool to help subprime car lenders such as AmeriCredit Corp. (NYSE:ACF) fight defaults, help the repo man reclaim the assets, and protect against car theft.

Sekurus' ON TIME system patches a legal wireless-controlled device into the car's electrical system. The consumer is given a wireless control that he must push before he can start the car, which sends a signal to Sekurus. The company verifies that financing is up to date before authorizing the car to start. The customer begins receiving a countdown three days before the vehicle is disabled.

The system also serves as a theft deterrent, since car thieves won't be able to start the car without the wireless remote.

The product is especially useful for sub-prime car loans, a $75 billion market. The company claims that, because lenders can depend on this system to increase pay rates and reclaim vehicles, it will result in more borderline drivers receiving financing that otherwise would not. ON TIME also can be used by new dealers who have problems with cars being stolen off their lots.
