In a report published Friday, Goldman Sachs analyst Judy Hong defended Keurig Green Mountain Inc , noting that after analyzing the bear thesis, "asymmetric upside risk" does exist, but shares at its current price offer a "compelling investment opportunity" for long-term investors. Shares of Keurig have been under pressure due to concerns around a slowing installed-base growth, market share losses for its own k-cup pods resulting in gross margin declines and "skepticism" around its cold-beverage machine, which might "flop."
