Amazon CEO Jeff Bezos is no stranger to spending the company's cash if he believes it will help the business long term, and it's hard to argue with that strategy, given the share price performance over the past five years. Amazon shares have gained 332.53%, versus a 21.57% return for the Nasdaq. Investors will also be looking for any mention of weakness in Europe. Amazon generates a healthy percentage of its revenue overseas, but with so many European countries mired in recession (Spain, Greece, Italy, U.K, to name a few), sales deceleration may put a black mark on the quarter. J.P. Morgan analyst Doug Anmuth points to channel checks from ChannelAdvisor, comScore ( SCOR), and earnings from eBay ( EBAY) and Google ( GOOG) as indications that U.S. e-commerce may in fact be accelerating, despite concerns over Europe. "ChannelAdvisor data suggests a significant deceleration in Amazon's 1Q SSS Same-Store-Sales growth to 51% Y/Y vs. ~64% in 4Q," Anmuth wrote in his research report. "comScore data suggests non-travel eCommerce accelerated to 17% Y/Y growth in 1Q from 14% in 4Q. In addition, comScore shows Amazon's US traffic grew ~30% -- a slight deceleration from 4Q -- and suggesting underlying user growth trends remain strong." The analyst rates Amazon shares "overweight" with a $210 price target. Investors will be keen to hear any update Amazon has about its consumer electronics strategy, namely the Kindle Fire. It's widely speculated that Amazon sells the Kindle Fire at breakeven or perhaps even a slight loss to drive traffic to its site, but there is little known about the growth of the device and its effect on margins. Bernstein analyst Carlos Kirjner notes a back-of-the-envelope estimate suggests that the Kindle Fire could positively impact first-quarter revenues by $300 million to $500 million, but it's dilutive to gross and operating margins. Kirjner rates Amazon shares "overweight" with a $239 price target. Investors may also look to see whether UPS ( UPS) weakness is related strictly to UPS, or relates more broadly to Amazon, as UPS is one of Amazon's largest shippers. Shares of Amazon are lower in Thursday trading, off 0.49% to $193.47. Interested in more on Amazon?
