Starbucks has somewhat fallen out of favor with Wall Street -- since the company had cautious things to say regarding changes in how goods are being consumed in January, investors are wondering if Starbucks is operating at its full potential. Belus Capital Advisors' Brian Sozzi reveals one huge problem affecting Starbucks: profit margin-killing promotions. The coffee chain's efforts to reignite customer traffic it lost during the holiday season could be why the stock is underperforming.

At the time of publication, Sozzi was long XXX, although positions may change at any time.

At the time of publication, Sozzi held no position in the stocks mentioned.
