Amazon’s shares have taken a hit after the online retailer reported a 57% drop in profit during the fourth quarter.
 

According to Reuters, investors appear to be growing weary of Amazon's long-running campaign to bolster its digital offerings and distribution networks, in line with CEO Jeff Bezos' strategy to sacrifice short-term profit for long-term success.
 

Amazon has been growing at least twice as fast as the e-commerce sector in recent years. To keep up that pace, the company is expanding into new categories and regions, spending heavily on growth and crushing profit margins.
