Amazon.com (NASDAQ:AMZN) has been having a tough time over the past few months as it tries to convince investors that its massive lead in e-commerce also makes its shares a better bet than those of other technology giants.

The problem that the largest e-commerce company in the U.S. is facing isn’t that complicated though. According to Amazon, it has to spend massively to grow further —and as costs add up, they are going to put pressure on gross margins.

Amazon's shipping costs rose 46% in the third-quarter, after growing 36% in Q2 and 21% in Q1, helping its gross margin to shrink 0.7 percentage points annually to 41%. For the fourth quarter, which is a seasonally weaker period for margins, the consensus is for Amazon's GM to be down further 0.5 points to 37.7%.

The company’s costs, tied to its one-day delivery service known as Prime, are what's driving up expenses. And the investment needed to dispatch merchandise in one day will continue to put a strain on earnings for the rest of the year, according to Amazon.

That situation isn’t encouraging for short-term investors who were attracted to this stock by the company’s growing profitability. Its shares, which have sky-rocketed more than 400% over the past five years, have, however, done nothing for investors in the last few months.
