Amazon (NASDAQ:AMZN)

If Amazon.com were simply the largest U.S. online retailer (by a wide margin), it would be a worthy investment based on its volume of sales and its ability to find new ways to get customers to spend more (see: Amazon Prime). But there are many more ways for this behemoth to win. From cloud computing to drones to artificial intelligence, Amazon is placing sizable bets in many cutting-edge industries, any of which could add substantially to the bottom line over time.
