Short-selling: Everything you need to know

What is short-selling?

Short-selling is the act of selling an asset that you do not currently own, in the hope that it will decrease in value and you can close the trade for a profit. It is also known as shorting. Short-sellers tend to use this strategy as a method of speculation or as a way of hedging downside risk.

Short-selling strategies can be carried out via a broker, but it is a complicated method, which means that it can be difficult to find a broker willing to lend you the shares to sell. This is why derivative products such as CFDs are becoming an increasingly popular method of short-selling.



In finance, being short in an asset means investing in such a way that the investor will profit if the value of the asset falls. This is the opposite of a more conventional “long” position, where the investor will profit if the value of the asset rises. There are a number of ways of achieving a short position.

Example of short-selling

Let’s say that the shares of company ABC are currently trading at $75, but you believe that they are going to decline in value and decide to short-sell the stock. You borrow 100 shares of ABC from your broker and sell them on the open market.

Over the next week the market drops significantly down to $40, so you close your short position and buy back 100 shares of ABC at $40 each.

You calculate the difference between the price of the shares when you borrowed them (75 x 100 = $7500) and the price that you re-bought the shares for (40 x 100 = 4000), which gives you a profit of $3500 – excluding any commissions and costs your broker may charge.

However, if you had been incorrect and the market had continued to rise, your potential risk is infinite. Because you have borrowed the stock, your broker may ask for them back at any time and you would have to close out your position at a loss.

In terms of practical realities, you can limit your risk with a stop-loss order – an order to close out your market position if your loss reaches a specified amount. Just as if you’d bought Z stock at $90 a share, you’d likely close out your position in the stock long before it fell to $0 – if you sold Z short, you’d likely close out your position long before the price rose to $500 a share.
To avoid any confusion, it helps to focus on the fact that in terms of profit or loss, short trades work out essentially the same as long trades. When all is said and done, you’re hoping to have closed out the trade with a sell price that’s higher than your buy price, because that means you made money on the trade.

Pros and cons of short-selling

Pros of short-selling

Short-selling means that you have the opportunity to profit from markets that are declining in value, not just ones that are increasing.

Short-selling can be carried out in a variety of ways. The example above demonstrates the traditional method of short-selling via a broker, but traders will define short-selling slightly differently to investors. Thanks to the rise of online trading and derivative products – such as CFDs – traders can take a short position on thousands of markets without having to borrow the underlying asset.

They can be used in a speculative manner, taking naked short positions, or for hedging purposes (such as part of a spread trade).

Cons of short-selling

Short-selling can be a risky strategy, as assets can theoretically increase in value indefinitely. Leveraged products can increase risk further, amplifying losses when a market is heading upwards in price.

A good risk management is key when short-selling, using tools like guaranteed stops to prevent excessive losses. Using a guaranteed stop on the IG platform will incur a fee if the stop is triggered.

There’s also a recall risk, in the event that the stock lender wants to liquidate their position and therefore recalls the stock lent out, which in turn forces the borrower to liquidate their position at a potentially unfavourable time.
