Horizon/CMS Under Inquiry Over Stock Trading: The Albuquerque-based operator of nursing homes said recent trading in its stock is under investigation by the Securities and Exchange Commission and the New York Stock Exchange. The SEC and the NYSE are looking at trading around the time of four Horizon/CMS Healthcare Corp. announcements; including a revised earnings estimate, a lawsuit filed by Horizon, a merger deal and a federal investigation into the company’s Medicare billings. Horizon Chairman Neal M. Elliott sold company shares valued at about $662,000, and other current and former company insiders sold about $36 million in shares in January and February, according to the Wall Street Journal, which reported the investigation.
