(AMZN) - Get, Inc. Report

is scheduled to post second-quarter results after the closing bell, and

once again

, investors will be monitoring the online retailer's razor-thin margins and the affect of Europe's

macroeconomic weakness


The Seattle, Wash.-based company has spent the last few years pouring money into upgrading its warehouses, developing new technology and improving its digital library for its electronic devices. Last quarter, for example, it acquired robot manufacturer

Kiva Systems

to operate its shipping centers. Although the spending has caused Amazon's revenues to surge, it has pressured the company's bottom line.

Amazon's total worldwide operating margin was 1.5% during its fiscal first quarter. By way of comparison, e-commerce giant


(EBAY) - Get eBay Inc. Report

operating margin was 20.5%, or 27.3%, excluding items, during its most recent quarterly results.


(AAPL) - Get Apple Inc. (AAPL) Report

, which touts its iPad against Amazon's Kindle Fire, reported an operating margin of 33% in its third-quarter results on Tuesday.

BMO Capital Markets expects that Amazon's margins will be in the


for some time. "We expect the company to spend heavily in fulfillment centers as well as technology and content to drive this robust growth, compressing operating margins in the short term as a result of these expenditures," explained the research firm, in a recent note.

Nonetheless, BMO rates Amazon 'market perform', predicting continued robust revenue growth.

Amazon did not report a gross profit margin during its first-quarter results earlier this year, although


estimates it was 23.95%. Apple's most recent gross profit margin, in contrast, was 42.8%, while retailer


(TGT) - Get Target Corporation Report

had a gross profit margin 30.2%.

Carlos Kirjner, an analyst at

Bernstein Research

, rated Amazon 'outperform' with a target price of $251 in a note to clients on Monday. He projects 32 cents of earnings for the second quarter, "driven primarily by gross profit margin expansion."

Amazon's shift to selling more of its products through third parties and the growing popularity of Amazon Web Services is seen as benefiting the company's margins. The company's mix shift is yet to be fully incorporated into consesus estimates, providing upside opportunity, according to Kirjner.

After eBay and

second-quarter commentaries suggested growth in the UK and northern Europe,

Think Equity

analyst Ronald Josey raised Amazon's price target from $235 to $250 and reiterated his 'buy' rating in anticipation of strong second quarter results.

"2Q12 results from eBay and Google suggest to us that European e-commerce trends remained strong in the quarter and we believe Amazon should benefit here as well," he wrote in a research note on Tuesday. "Additionally, we believe the shift to Third-Party sales should help subsidize Amazon's investments in Fulfillment Centers and international expansion, though we note a strong USD could impact guidance for 3Q12."



(UPS) - Get United Parcel Service, Inc. Class B Report

, one of Amazon's largest shippers, cited the macro environment in Europe as a challenge for the quarter.

A number of tech heavyweights have already identified tough economic conditions on the other side of the Atlantic. Chip giant


(INTC) - Get Intel Corporation (INTC) Report

, for example, lowered its full-year guidance last week amidst a softer-than-expected European spending climate.

Texas Instruments

(TXN) - Get Texas Instruments Incorporated Report

also identified cautious spending in its

second-quarter results

earlier this week.

Analysts expect Amazon to report 2 cents of earnings on $12.89 billion of revenue in the second quarter.

The online retail giant's shares have risen 12.13% since the company announced its

first quarter earnings

at the end of April. Shares rose 1.07% to $218.12 during Thursday trading.
