“The National Highway Safety Administration could push through a major regulation change that would generate a significant amount of business for one specific auto-part maker, “Jim Cramer said on a recent “Mad Money” TV show. He explained that the feds could mandate that all light vehicles sold in the U.S. have a rear-camera display. Keep in mind that a decision isn’t expected until February 2011, but a yea vote would be very big for Gentex Corporation (NASDAQ:GNTX). “And you have to be in way before that to make easy money,” Cramer said. He called the company a technology-based auto-parts maker. The company makes a number of high-tech mirrors, like those with integrated compasses, General Motors’ OnStar system, HomeLink garage door openers, tire-pressure monitoring, voice recognition, LED turn signals and even rear view camera displays. Cramer said if the bill that will require rear-camera displays on all cars sold in the U.S. passes Congress, then Gentex will reap big rewards because some 60% of all new cars would likely opt to put real-view displays in their mirrors, a market where Gentex has 80% market share. “The company could make money hand-over-fist by simply incorporating these displays into its rearview mirrors,” Cramer said. However, one problem with the company is their exposure to Toyota Motor Corporation (NYSE:TM), which makes up 17% of sales. But Cramer thinks the 10,000 unit per week production decrease as a result of Toyota’s recall issues could be made up by a jump in sales to other customers like Ford Motor Company (NYSE:F). Gentex has a great balance sheet with $353 million in cash and no debt, and earnings are predicted to grow 79% in 2010 and another 21% in 2011. The current y dividend yield on the stock is 2.2%, and shares trade at around 24 times this years numbers, though it historically has traded at 25 to 30. Cramer said there’s plenty of room left for GNTX to run.   Join the fastest growing community of small cap investors at Stockhideout.com
