Amazon seems bent on completing the tower of babel that it has already started building. During the Thursday trading session the company stock managed to gain more points and close at $2399.45 and has a pre-market value of $2421.72. Goldman Sachs chief analyst in a note published on Thursday said they were raising their price target to $2900, a whole 20% upside from the current level. Goldman Sachs expects the increase to be driven by an increase in demand in several of the company's businesses. The Analyst says the growing demand for Amazon's retail, cloud and advertising businesses will "steepen the curve of its long term growth rate, drive incremental profitability and further deepen the competitive moat around all of its businesses''
