Frischer Tageskommentar des Motley Fool: "Why BioNTech Stock Sank Today
An analyst expressed concern that no news so far from a late-stage study of coronavirus vaccine BNT162b2 could be bad news.
What happened
Shares of BioNTech (NASDAQ:BNTX) were sinking 6.2% lower as of 3:33 p.m. EDT on Monday. The decline appeared to result from speculation by Bernstein biotech analyst Vincent Chen that the coronavirus vaccine candidate BNT162b2 developed by BioNTech and its partner Pfizer (NYSE:PFE) could have lower efficacy than expected.
So what
Chen thinks it's likely that BioNTech and Pfizer have had two interim analyses from the late-stage study of BNT162b2 already. The partners have publicly stated that preliminary efficacy results could be announced in October. Because the companies haven't announced any data yet, Chen suspects that the vaccine could have had a lower efficacy than initially hoped.
However, there are plenty of other reasons why the companies might have opted to hold off on announcing preliminary late-stage efficacy results. For example, Pfizer provides its third-quarter update on Tuesday morning. It's possible that the big drugmaker wanted to wait to report the results for BNT162b2 at the same time.
The bottom line is that at this point any discussion of the efficacy of BNT162b2 is purely speculation. And as long as the vaccine doesn't have worrisome safety issues, an efficacy of 50% or more will be enough to win FDA emergency use authorization.
Now what
We should soon know how well BioNTech's experimental coronavirus vaccine is faring in late-stage studies one way or another. In the meantime, the biotech stock will likely remain relatively volatile -- especially with increased choppiness in the overall stock market."

Kurzfassung: Der heutige Kursverlust geht wohl auf die Spekulation des Bernstein-Analysten Chen zurück, BNT162 könnte weniger effektiv als erwartet sein, weil bis jetzt noch keine Daten vorgelegt wurden. Na und? Es gäbe diverse andere Gründe, aus denen die Daten noch nicht vorgelegt wurden - beispielsweise, weil dies bei Pfizers morgiger Präsentation geschehen soll. Und selbst wenn die Effektivität nicht sonderlich gut sei - so lange es keine schweren Verträglichkeitsprobleme gäbe, sollte 50% Effektivität immer noch für FDA-Zulassung reichen. Und jetzt? Wir werden bald wissen, wie gut sich der Impfstoff im letzten Studienabschnitt geschlagen hat. Bis dahin bleibe die Aktie wohl weiter volatil - insbesondere im augenblicklichen Börsenumfeld.
Kann man aus meiner Sicht genau so stehen lassen. |
