There are plenty of other online retailers. Etsy, walmart, jet, overstock, newegg, etc. Nothing is stopping people from using them. Amazon doesn't leverage there position to prevent compotition. They're just better.

Amazon certainly does leverage their position to prevent competition, why else do you think they hardly turn a profit? There may be plenty of other online retailers but it doesn't negate the fact that Amazon has over 50 percent of the market share. Enjoy your long positions before antitrust gives them a slap on the ass, because I'll be 20 miles away. Why take that kind of risk when you can have positions such as baba and tencent, where their government actually wants them to continue growing.
