What is short-selling? http://www.contracts-for-difference.com/Shorting-questions.html Going Short as a Trading Strategy. CFDs also allow you to benefit from any market conditions providing you deal the right way. Not only can you profit from a rising share price by 'going long' but you can also benefit from a falling share price by 'going short' (i.e. sell a CFD on a share you do not own)
