What is shorting selling ?

Selling short is simply profiting when a price falls. If the price was 100 and the price goes down to 75 you make a profit of 25. Conversely if the price went up from 100 to 125 you would make a loss of 25.  

How does short selling work?

Shortling is a strategy that can be used in either investing or trading. Essentially shorting allows you to speculate on assets that you believe will fall in value, allowing you to potentially benefit from falling markets rather than just relying on traditional (long) buy only strategies.

We know shorting allows you to speculate on markets that are falling. However the process is not as simple as buying an asset and waiting for it to go up, before you sell to make a profit. To take a short position it would normally involve you borrowing the asset then selling the asset and buying it back at a cheaper price. Returning the asset and keeping the difference as your profit.


Stage 1

You borrow the asset (AstraZeneca shares at £80)

Stage 2

You immediately sell the asset (AstraZeneca shares at £80)


As you are a short seller, you expect the shares price to decrease. On this occasion you are right, and AstraZeneca shares drop to £78


Stage 3

You purchase the shares back (AstraZeneca shares at £78)

Stage 4

You return shares to the lender

Stage 5

Receive profit or lose. On this occasion you make £2

Benefits of short selling with derivatives?

Short selling with derivatives, such as CFDs and Spread betting simplifies the whole process for you, eliminating the stages above. Allowing you to speculate on just the price movements of the assets, without ever owning them or needing to go through the process of borrowing the assets.


To be a short seller you simply choose the assets and amount you want to short sell and execute the trade. Making a profit or loss on just the price movement. You can short sell most assets, including shares, indices, forex, and commodities.

How to short a stock?

Here is a worked example of short selling a stock.


AstraZeneca shares are trading at £80 and you think the price will fall.


You open a short position of 1,000 AstraZeneca shares at £80, two days later the AstraZeneca shares have dropped down to £78. You decide to close your position.


Your profit would be the difference between the open price of £80 and sell price of £78. Therefore as you bought 1000 shares, it is 1,000 shares x £2 = £2,000 profit before commission. 

However, if the price of AstraZeneca shares had risen by £2 you would have lost £2,000 before commission.

How to short an index?

Here is a worked example of short selling an index. (FTSE 100 contract at £10 a point)


The FTSE 100 is currently trading at 7400 with a spread of 7399–7401


You believe that the FTSE is going to fall and short sell 1 FTSE contract. You are selling the contract, so the sell price is at 7399. As the contact is £10 a point your exposure level is £10 x 7399 at a total value of £73,990.


Later the FTSE has fallen to 7299, with a spread of 7298–7300.

You decide to close your short position and take a profit by buying back 1 FTSE contract at 7300. As the contact is £10 a point your closing level is £10 x 7300 at a total value of £73,000. Which provides you a profit of £990. Which was a downward move of 99 point at £10 a point = £990.   

Short selling risk

You should be aware, with shorting, unlike a traditional long (buy) position which can only go to zero, a short position has unlimited downside: for example, a stock could go up from £1 to £11 (or more).


If you had a short position at £1 you could lose 10 times your investment ie 10 x £1 rather than the £1 you would have lost if you went long (buy) and it went to £0.

Why short sell ?

For profit


Short selling allows you to take advantage of a whole new set of opportunities. You can profit from the many assets that come under selling pressure at some point due to geopolitical uncertainty, economic news, supply and demand shocks and company mismanagement.


To hedge risk


Short selling allows you to hedge your risk, in a given asset, for a certain amount time. You are long and short of the same assets and therefore eradicating risk, but only whilst the hedge is active.

Short selling opportunities

Companies being mismanaged

If you believe the management team of a company are failing and are making poor decision. This will directly impact result in the company, eventually causing the price to fall.


Missing targets

Companies have an obligation to report the market at regular intervals their progress and financial numbers. This means the company and analysis give forecast of what they believe will be achieve. If these forecasts and expectations are missed, this can cause a negative impact on the share price.


Failing business models

If you believe the future demand for the service or company is going to decline, then the likelihood is the share price will do the same. For example, if you are a company that owns a chain of petrol stations and the government wants all cars to be electric which are going to be charged at home.

  • How to open a spread betting demo account ?
    To open your demo account, all you need to provide is a valid email address, your full name, phone number, username, and password. Open demo now
  • What can I do on the spread betting demo account ?
    The demo account is there to make you comfortable using the platform and provide a realistic trading experience. The demo trading account allows you to trade CFDs and Spread bets with access to over 17,000 markets to practice on, including shares, indices, FX, commodities, and cryptocurrencies.
  • What is important to remember with a spread betting demo account ?
    There are circumstances that we just can’t recreate for you. We can however from our experience, try to prepare you for them. With the demo account you have no emotional commitment or real financial consequences for your actions, and this can lead to over trading. You should try and replicate your demo trading plans as closely as possible to your real trading plans. For example, trading size, exposure, and trading instruments. You start with balance of £10,000, however more virtual funds can be added. Practise placing trades and closing trades, so that when you see an opportunity on the live platform, you can execute those trades even when the pressure of trading is high.
  • What are the differences between a spread betting demo and live account?
    A demo account provides a risk-free environment for you to try our web trading platforms. While much of the functionality of the live platform features in the demo, there are key differences to be aware of, including (but not limited to): ​ Trades made through the demo account will not be subject to slippage, interest and dividend adjustments, or out of hours price movements. Trades may be rejected if you have insufficient funds to open them, but, unlike on a live account, will never be rejected on the grounds of size or price. You will not be charged for chart packages on a demo account. Trades will not be closed if you have insufficient funds to cover margin and running losses, which can happen on a live account. ​ This is by no means an exhaustive list, therefore before opening a live account we recommend you read the information available on our website as well as the Customer Agreement to ensure that you are aware of the features of a live account
  • How do I move from a spread betting demo to a live account ?
    From the platform you simply click the “upgrade to live account” button on the top right and complete the application.
