One of the most interesting statements you hear as an uneducated investor, either from some news organization or from your Uncle Larry–an expert on, well, everything– is that short selling stock is a bad thing. As a “shorter,” you are evil since you want a company to fail, want their stock to go down, want their dog to die. You mean person. But in reality, is short selling really bad? Is it something we should avoid as budding investors?
First, a little about short selling (aka: shorting, shorting a stock). Shorting a stock is borrowing a stock. Since you don’t own the stock, you must replace it when the owner wants it (or you are done with it).
Here is a timeline for shorting a stock successfully:
- You decide a stock is overvalued. For an example, we’ll use Netflix. Right now, Netflix is trading for about $75. If you feel like the stock will go down $5 this week (or today or this month), you could decide to short that stock. (Note: the stock must be in an “uptick” or not be falling to short it.)
- You tell your broker (online or person) you want to short Netflix. You BORROW 100 shares of Netflix; this is borrowing from other investors using the same broker that own Netflix stock. You then sell the shares you borrowed for the current market value of $75. This will leave your assets at $7500 and your liabilities (what you owe) at 100 shares of Netflix stock.
- At the end of the week, you are right (nice job!) and the price is now $70 for a Netflix share. You buy 100 shares of that stock and then give back those shares to the person who you borrowed them from. This would leave you with no liabilities, since you replaced what you borrowed. But in your assets column, you will have the price you sold the stock for minus the price you replaced the stock for ($7500-$7000), leaving you with a $500 profit. Not bad!
That is the general idea behind shorting a stock. In traditional investing in stock, to be successful, it is imperative to buy low and sell high. This is key in business, investing, etc. In shorting, you at still doing each of these, but in reverse order. In short selling, you sell high and then buy low. Regardless of order, a profit is made.
What is the benefit of shorting a stock? One benefit is using knowledge that a company is overpriced to turn a profit. This allows for investors to profit from both a stock’s going down or going up.
Keep in mind, there are caveats to shorting a stock. The biggest of which is that potential losses outweigh potential gains. The potential gain when shorting a stock is limited by how low a stock can drop. On the other hand, the price a stock can increase (in theory) is infinite. Of course, there are ways to limit losses (stop order, etc.), but it is important to understand either way. This is contrasted with “going long” or traditional investing, where the potential losses and gains are exactly the opposite of shorting.

Potential Gains and Losses in Short Selling
The next question: Is short selling a bad thing?
The short answer, at least from my research, is NO, SHORT SELLING IS NOT BAD.
While some think shorting a stock leads to volatility in the market, the actual result is LESS volatility. In shorting, there are both more buyers at the low prices and more sellers at the high prices. This will lead to lower highs and higher lows.
This decrease in volatility is good for investors. Less volatility means fewer short term losses for traditional investors.

Market With and Without Short Selling
Opponents to shorting of stock say untrue rumors get started, driving a stock down, helping those who short stocks while hurting normal investors.
There are ways the market doesn’t allow this (or at least limits it). One regulation prevents shorting a stock that is already on the decline, so investors won’t “game” the market by driving the price lower and then profiting by “going long” as the price goes back up to the proper level (a price equal to the company’s worth or investors’s perception of that worth).
There are instances where short sellers game the market, but these are limited. More times than this happens, though, company executives drum up rumors/do other shady things/cover up bad practices to increase the price of the stock to help the company. While naughty short sellers try to convince investors a stock is worth less than it really is, many companies try convincing investors their stock is worth more than it really is. Some of the methods for doing each can be less than honorable. This doesn’t say short selling is bad any more than it says all companies are bad. It is just the nature of the market.
So is short selling a bad thing? I would say no, but I’m by no means an expert. You do your own research. Or you could just trust your Uncle Larry.
