Over on CAPS, fully 582 of the 609 All-Star members who have rated Amgen -- some 95.5% -- believe the stock will outperform the S&P 500 going forward. These bulls include sumbawa and TSIF, both of whom are ranked in the top 20% of our community.

Last month, sumbawa tapped Amgen as a brilliant biotech bargain: "Low valuation, low debt, strong cash flow, promising pipeline. Stock will probably hold up well in any forthcoming correction."

In a pitch from two weeks ago, TSIF kindly updates our community on Amgen's high-profile bone drug:

Amgen is a profitable biotech with some good products. Cash to debt is excellent, cash flow good and strong margins. It has strong partners for some of its products such as Wyeth (NYSE:WYE) and Johnson & Johnson. Even with strong products the key to success is new product releases. Next up for Amgen is a date with the FDA on October 19th for hopefully a decision on Denosumab for osteoporosis and some cancer indicators. Amgen is a good bet with or without product approval to be a market outperformer. The odds for approval on October 19th for Denosumab sweeten the prospects to a green thumb from me.
