Rating Change #10

Gentex Corporation (GNTX) has been downgraded by TheStreet Ratings from buy to hold. The company's strengths can be seen in multiple areas, such as its robust revenue growth, largely solid financial position with reasonable debt levels by most measures and growth in earnings per share. However, as a counter to these strengths, we also find weaknesses including a generally disappointing performance in the stock itself, poor profit margins and disappointing return on equity.
