Arena Pharmaceuticals (NAS: ARNA) , one of a trio of companies developing treatments for the obesity market, released its Q3 earnings after the market closed yesterday. Despite a fairly neutral report -- which didn't include sales projections for its FDA-approved drug Belviq -- the company is trading down today.

In the following video, health care analysts Max Macaluso and Brenton Flynn examine Arena's results, including a new partnership deal, and discuss the cascading effects of the poor sales figures reported by Arena's main competitor, VIVUS  (NAS: VVUS) .

VIVUS' poor Qsymia sales may have spooked investors who have high hopes for obesity drugs, but this doesn't necessarily spell the end for these companies. Despite the recent pull-back, Arena's shares are still up more than 270% year to date. Is Arena still a stock to watch, or is its growth potential evaporating?
