NEW YORK ( TheStreet) -- Given Imaging (Nasdaq: GIVN) has been upgraded by TheStreet Ratings from hold to buy. The company's strengths can be seen in multiple areas, such as its revenue growth, largely solid financial position with reasonable debt levels by most measures, expanding profit margins and increase in stock price during the past year. We feel these strengths outweigh the fact that the company has had sub par growth in net income. Given Imaging Ltd. develops, manufactures, and markets diagnostic products for the visualization and detection of gastrointestinal tract disorders. The company offers Given System, a wireless imaging system that uses PillCam capsules, which are disposable video capsules.
