When you short a stock you are betting that the price of the stock will go down. You do this by borrowing shares of stock from your broker and sell it. The money goes into your brokerage account and you later buy back the stocks you owe, called covering. If you price of the stock goes down, you spend less to buy back the same amount of shares you borrowed and thus you make money. If the price goes up, you have to spend more to buy the stocks that you borrowed and thus you will lose money.
Let’s look at an example:
Let’s say you tell your broker you want to short 100 shares of Google which is now trading at $500. You would borrow 100 shares of Google and sell it immediately giving you $50,000 in your account. Sounds good, but remember you still owe the 100 shares of Google back. Now suppose Google drops to $400 after missing on quarterly earnings. You decide its time to buy the stock back, or cover the stock. You tell your broker you want to cover the 100 shares of Google. You would then buy the 100 shares at $400 for a total of $40,000. You started with $50,000 on the initial sell and only had to use $40,000 to buy the shares back that you owed giving you a profit of $10,000.
Much of what happens with most online trading brokerages is behind the scenes. If you wanted to initiate a short on a stock you would specify the ticker symbol and amount of shares, much like buying stocks, but you would click on the ‘short’ button instead of ‘buy’. Then when you are ready to close the trade you would use ‘cover’ button to buy the shares back.
A few things of note regarding shorting stocks. First, you must have a margin account to short stocks in case the stock goes up, you won’t have enough to cover with sale and must borrow money. Secondly, sometimes shares are not readily available to be borrowed. Lastly, if the stock you short pays a dividend during that time you are short, you must pay the dividend.
