Why BHVN stock is down today

BHVN stock fell 2.72 percent to $15.02 on Monday. The decline followed a -2.8 percent opening gap from the prior close of $15.44. The stock has traded in a narrow range during the session with a high of $15.79 and a low of $15.00. The move comes amid mixed news on the company’s clinical pipeline and recent analyst activity.

What Happened

Biohaven announced it will present new clinical data on BHV-1530 at the ESMO Congress, a novel FGFR3-directed ADC with a proprietary Topoisomerase I payload. The company also announced a new clinical supply agreement with Regeneron to evaluate BHV-1530 in combination with cemiplimab (Libtayo®). Early clinical activity from the Phase 1 dose-escalation data showed signs of tumor reduction. Meanwhile, a recent report warned that Biohaven’s lead drug may struggle to stand out in its competitive space. B of A Securities downgraded Biohaven to Underperform and lowered its price target to $11. These developments contributed to investor caution.
