Why is short-selling considered more “advanced” than a simple buy?
The margin rules are also more complicated.  A simple buy on a non-margin account will never run into margin rules and you can just wait out any dips if you have confidence the stock will recover.  A "simple" short sell might get you a call from your broker that you have a margin call, and you can't wait it out without putting more money in.  Personally I have trouble keeping the short sale margin rules straight in my head, at least compared to a long sale. I got in way over my head shorting AMZN once, and lost a lot of money because I thought it was overvalued at the time, but it just kept going up and I wanted it to go down.   I've never gotten stuck like that on a long position.
