Regeneron (REGN) upgraded to Buy from Neutral at Citi with analyst Mohit Bansal saying the Libtayo data in 2020 and continuous Dupixent growth will make it easy to keep owning Regeneron shares through near-term Eylea competition. 2. Match Group (MTCH) upgraded to Buy from Neutral at UBS with analyst Eric Sheridan saying Match shares experience a post-earnings selloff yesterday after already being notably down since August on the back of the Facebook (FB) Dating launch and legal proceedings. 3.
