CELG, from David Lillienfeld
Rocky's looked at natural gas; I follow biotech pretty closely. While some of the real biotechs (the ones with products in the marketplace) are doing OK, Celgene looks a bit extended. Its PE is north of 30, and looking at its chart (and I'm nothing close to some of the technicians on this list), it looks like it finally broke down. Strange that Celgene broke but Regeneron did not.
