Let’s say that the value of the company in question is £112 per share at the moment. At the same time you forecast that due to the current market turmoil and situation in the sector the company is not going to deliver and the equity price is going to fall. After assessing your risks you think that odds are in your favour and you decide to sell at £112. Now you have an open short position and wait for the price to fall, so you can buy the share back later to close it with profit.
