JP Morgan cut its rating on the stock to "neutral" from "overweight", saying an analysis of the world's biggest Internet retailer's key business lines suggests a slower growth in gross profit in 2013. It slashed its price target on the stock by $33 to $300.
"The key drivers of gross profit deceleration are: moderating growth in third-party sales from 51 percent in 2012 to 37 percent in 2013; 2) first-party gross profit margin potentially contracting due to international expansion and rebounding eReader/Tablet sales; and 3) tougher comps," analyst Doug Anmuth wrote in a note.
