Why Amgen (AMGN) Stock Is Up Today

Amgen (AMGN) is up 4.1% today. Here is some analysis on what might have caused this price movement.

Analysis: The most likely driver appears to be a rebound after last week’s sharp selloff tied to worries about the Lp(a) drug class, with investors warming to the view that Amgen’s olpasiran program may still be differentiated. Sentiment may also be getting support from recent commercial and regulatory progress for Imdelltra, which could improve uptake.

Details:

A recent Wall Street note argued that Amgen’s olpasiran has a different profile than a rival Lp(a) program that disappointed earlier this month, helping calm fears that the entire category is impaired.

That matters because Amgen shares had dropped hard after the rival trial miss, so part of today’s move could be a relief rally as investors reassess whether the earlier reaction was too severe.

Amgen management also discussed the business at a major healthcare conference in mid-September, keeping attention on late-stage pipeline assets and the company’s longer-term growth setup.

Separately, Amgen said the FDA approved reduced monitoring time for the first two doses of Imdelltra, a label change that may make treatment logistics easier and support commercialization.
