Gentex Corporation (NASDAQ: GNTX) manufactures automatic-dimming rear-view mirrors, camera-based driver assistance systems, and the HomeLink Wireless Control System for the global automotive industry.

The company is based in Zeeland, Michigan and was founded in 1974. Their mirrors use electrochromism to dim in proportion to the amount of light reaching them from following vehicles' headlamps. The mirrors are available with added electronic features. About 98 percent of the company's net sales are derived from the sale of auto-dimming mirrors to every major automaker in the world.

Gentex has been a target of short sellers for a while. The current short interest of 7.95% is significantly above the average of the last 12 months (4.91%).
