Amazon.com‘s (NASDAQ: AMZN) third quarter didn’t quite live up to expectations, with earnings per share coming in at about 33% below analysts’ average forecast. No-joke spending — something Amazon investors are intimately familiar with — was to blame. Despite shareholder familiarity with Amazon’s heavyweight spending habits, Wall Street didn’t welcome the sudden pullback in profit with open arms. Shares sold off about 5% after the quarterly report was released, as investors digested the implications of this higher-than-expected spending.
