How does short selling work in stocks?
When it comes to stocks or other securities, short-selling is a way to make a tidy profit when planned well. An investor borrows stocks or other tradable securities that they believe will decrease in value from a brokerage or other party willing to loan them (typically for a small fee). There's a time limit on how long they can borrow those stocks before they must be returned or purchased.
Generally, what happens in a stock short sale is that the borrower will put the stocks up for sale immediately, hoping that the price will drop substantially. If the price does drop, they will buy the stocks back and return them to the owners, pocketing the difference between the initial sale price and the buyback price.
So, for example, if I borrowed 10 shares of XYZ, Inc. from my broker when they were worth $50 a share with the intention to short, I'd turn around and immediately put them up for sale. The magic happens when that stock drops in value, say to $35. I have to buy the stock back to return it by the deadline, but now I'm only paying $350 to buy those shares, and I get to put $150 in my pocket (This is a very simplified example).
What is a short sale in real estate?
A short sale in real estate is something very different and happens when a distressed borrower is allowed to sell their home for less than they owe on it. This doesn't happen often in the kind of market we're currently experiencing, but when markets drop suddenly, you can see it quite a lot. It was a common practice during the Great Recession.
The homeowner has to get permission from the lender to sell their home short, but it is often in the lender's best interest to do so because it can be expensive to go through the entire process that's required to repossess a home and prepare it for sale. This way, the bank only loses the difference between the loan and the cash at closing, some of which may be able to be made up by the mortgage insurance (if any) on the shorted mortgage.
In some cases, the borrower will have to pay back the difference between their loan and the sale price, but it depends on the rules in the state where the sale happens, and this is considered at the bank's discretion.
