Why is Amgen stock sliding today?

Amgen (AMGN) stock fell 2.2% to $382.67 after HSBC downgraded it to Hold, cutting its price target to $425. The downgrade follows a competitor's clinical trial failure, which impacted Amgen's pipeline prospects. Analysts cited patent expirations and delayed pipeline benefits as concerns, though some reaffirmed Buy ratings due to positive trial data for Imdelltra.
