Regeneron's shareholders have been on a roller-coaster ride, though, with the stock plunging in 2016 but bouncing back somewhat this year.

What Regeneron has done in the past isn't nearly as important to investors as what the biotech could do in the future. Is the stock now a buy? Here are the arguments for and against Regeneron.
