Let’s look at a different scenario now. Assuming you sold the share at £112 in the hope the market would fall you watch now the development in the share movement and you see that the company was actually able to turn around and is actually making better than you predicted and the price is starting to go up and you see it is at £130 now. If you were to close out the position you would have made a loss of £18 per share. However, if you waited and saw the price raising even higher to £153 or £214 your losses would be even bigger.
