Barclays analyst Lauren Lieberman upgraded the beverage giant to overweight from equal weight in light of what she called a "thoughtful business transformation that's among the most comprehensive we've seen."

The transformation, which has picked up the pace since Quincey took the helm in May 2017, will better allow Coca-Cola to cope with a rapidly evolving industry landscape, Barclays analysts wrote. Barclays said it expects Coca-Cola to emerge as a "leader" in the broader consumer staples space, capable of managing "significant industry change."

The business transformation should drive "sustainably better growth," Barclays wrote, which ought to in turn yield a higher valuation premium. If the company can meet Barclays' estimates of about 5% organic growth and between 6% and 8% profit growth by 2020, Coca-Cola stock should trade at as high as a 25% premium to historical levels, analysts noted.
