Keryx Biopharma (KERX), AEterna Zentaris (AEZS) Get a Reality Check

March 6, 2012 8:30 AM EST
After zooming higher Monday, biotech stocks Keryx Biopharma (Nasdaq: KERX) and AEterna Zentaris (Nasdaq: AEZS) are both lower in pre-open trading Tuesday as there is now questions about analysis of the recent Seeking Alpha article which said FDA approval is "practically a done deal".

"The credibility of the author, Jeremy Richards, and the veracity of claims and statements made by him, couldn't be verified by anyone at his purported investment firm, the drug companies and Seeking Alpha," TheStreet.com's Adam Feuerstein writes Tuesday.

Keryx Biopharma is down 6 percent today after jumping 33 percent Monday and AEterna Zentaris is down 12 percent after ramping 23 percent higher Monday.
