Energy drink maker Monster Beverage (MNST) is climbing after UBS wrote that sales in foreign countries could enable the company to report significantly stronger than expected results over the long-term. ANALYST OPINION: The total market outside the U.S. for energy drinks is $20B, the firm estimated. By the end of 2016, international sales will lift Monster's earnings per share by $1, UBS predicted. Monster only recently launched operations in the second and third largest markets for energy drinks, Japan and Brazil, UBS explained. The firm raised its 2016 earnings per share estimate for Monster to $4.47 from $4.12 to more accurately reflect Monster's earnings per share opportunity and maintained a Buy rating on the shares. WHAT'S NOTABLE: On a negative note for Monster, evidence suggesting that energy drinks may not be healthy continues to increase. A study released yesterday by the Cleveland Clinic found that a dietary supplement used in the beverages can promote hardening of the arteries, according to The Plain Dealer. TODAY'S PRICE ACTION: In mid-afternoon trading, Monster jumped $2.40, or 4.8%, to $52.08.
