WHAT IS THIS ABOUT: On October 31, 2022, Marketwatch published an article entitled “Y-mAbs Therapeutics shares fall 42% following last week’s FDA advisory committee vote” which stated “[s]hares of Y-mAbs Therapeutics Inc. YMAB, [] plunged 42.5% in premarket trading on Monday after several banks downgraded the company’s stock and a Food and Drug Administration advisory committee voted against approval of the company's experimental treatment for neuroblastoma patients.”

The article further stated that the “committee on Friday voted 16-0 that there wasn’t enough evidence to say that omburtamab improves overall survival. J.P. Morgan downgraded the stock to underweight from neutral, with analysts saying: ‘We do not think recent newsflow bodes well for investor confidence or for ascribing further pipeline value to follow-on indications which are mostly in their early innings of development.’”

On this news, Y-mAbs’ stock fell sharply during pre-market and intraday trading on October 31, 2022.
