The reason for Aegerion's exceedingly rough year is that the company's flagship drug Juxtapid, indicated for genetically based high cholesterol, is facing stiff competition from the newly approvedPCSK9-inhibitors from Amgen and Regeneron .

Although Amgen and Regeneron's respective drugs have gotten off to an unexpectedly sluggish start in terms of sales, they should eventually grab a significant amount of Juxtapid's market share moving forward. So, the fact that a firm is actually upgrading this stock in light of these competitive threats is certainly good news for shareholders.

Now what:Guggenheim's change of heart appears to center around the company's shake up at the executive level earlier this year. Put simply, the firm seems to think the new members of management will make a meaningful difference in Juxtapid's competitive position. Personally, I'm siding with the rest of Wall Street on this issue, and think Juxtapid's sales will start to slide in a big way as Amgen and Regeneron's respective drugs gain acceptance among clinicians and patients alike. As such, I'm happy to watch this stock from the safety of the sidelines for the time being.
