Unfortunately, Amgen doesn’t look as hot when stacked up against only other biotech stocks. The poorer showing stems in large part from incredible runs by the two companies that make up a higher percentage of the ETF’s holdings than Amgen does. Both Regeneron Pharmaceuticals Inc (NASDAQ:REGN) and Gilead Sciences, Inc. (NASDAQ:GILD) are up more than 50% so far this year.

What about valuation? Amgen, Inc. (NASDAQ:AMGN)’s trailing price-to-earnings multiple currently stands at nearly 18. That doesn’t seem too high for a biotech stock. Looking at the company’s P/E history sheds a little more light, though.

If we look back over the past 10 years, Amgen stock looks downright cheap based on trailing P/E. However, its trailing P/E is actually now at the highest level since 2008.

Compared to other biotechs, Amgen’s valuation based on trailing P/E looks attractive. Regeneron Pharmaceuticals Inc (NASDAQ:REGN) sports a trailing P/E ratio of 35, while Gilead Sciences, Inc. (NASDAQ:GILD)’s multiple stands at 31. Biogen Idec Inc. (NASDAQ:BIIB) and Celgene Corporation (NASDAQ:CELG) are even pricier, with trailing P/E values near 37.

Amgen stock seems dirt cheap by comparison with these other biotechs on a forward P/E basis. Its forward multiple of below 13 is well below Celgene Corporation (NASDAQ:CELG)’s 18 and Gilead Sciences, Inc. (NASDAQ:GILD)’s 19. Biogen Idec Inc. (NASDAQ:BIIB) is even higher at 23, with Regeneron Pharmaceuticals Inc (NASDAQ:REGN) blowing the curve with a 43 forward P/E.
