“Going short” basically means you’re trying to make money off of something that you think won’t do well. It’s the opposite of “going long” or just buying a stock outright which is a vote of confidence in that company. It’s a more advanced trade because there is way more risk. If you buy the company outright, the most you can lose is 100% of the value. If you short it and it goes up more than 100% you can lose an unlimited amount of money—so be careful, and make sure that you think it’s going to go way down because you make the difference if you are right. You lose the difference if you are wrong. (See also: Long)
