Jefferies analyst Brent Thill raised his price target for Amazon.com to $1,750 from $1,450 saying the company last night delivered another beat with solid revenue growth in the core business and revenue acceleration for Wed Services. The stock in premarket trading is up 5%, or $67.00, to $1,457.00. The guidance for Q1 is “soft on margins as usual,” Thill tells investors in a post-earnings research note titled “No Barriers in Sight.” He believes the Q4 results “showcase once again” the embedded leverage in Amazon’s model. Thill continues to believe Amazon is best positioned to benefit from the secular shift of commerce from offline to online.
