OPKO Health (OPK) stock: Winston Score, insiders and Congress trades
OPKO Health is a healthcare company that makes diagnostic tests and pharmaceutical drugs. Its biggest business is BioReference Laboratories, one of the largest clinical lab testing services in the U.S., which processes blood tests and other medical tests for doctors and hospitals. OPKO also sells Rayaldee, a prescription drug used to treat vitamin D deficiency in patients with chronic kidney disease. OPKO makes money by charging for lab tests processed through BioReference and through prescription drug sales. The company operates mainly in the United States, with some international pharmaceutical operations in countries like Israel and Chile. With a market cap around $1 billion and a negative operating margin, OPKO is currently spending more than it earns, which is a key concern for investors. The main risk is that the lab testing business faces intense price pressure from larger competitors like Quest Diagnostics and Labcorp, while the pharmaceutical side depends heavily on growing Rayaldee prescriptions to move toward profitability.
