It’s been an up-and-down kind of year for Bristol-Myers Squibb (NYSE: BMY). Early in 2017, investors were concerned after the company opted not to pursue accelerated approval for a combination of Opdivo and Yervoy in first-line non-small cell lung cancer (NSCLC). Those worries largely evaporated, though, and BMS stock eventually went on to generate nice year-to-date gains.
