Sunrise Medical Stock Tumbles on Internal Inquiry: The stock of the Carlsbad-based company fell more than 35% a day after the medical products maker said it had launched an internal investigation into its financial controls and statements. After a delayed opening, the stock fell $8.375 to close at $15.125 on the New York Stock Exchange, where its loss was the biggest of the day. Late Thursday, Sunrise Medical Inc. said it had formed a committee of outside board members to oversee the inquiry, which is concentrating on the Bio Clinic and Comfort Clinic divisions of its Bio Clinic Corp. unit. The company’s net income and assets may have been overstated for previously reported periods. Sunrise executives were not immediately available for comment.
