“Short selling,” or “going short,” is a practice which enables traders to open a position that will increase in value if a financial instrument’s price goes down. This is used either when markets are falling, or as a hedging tool.One of the big advantages of investing in CFDs, rather than in markets like commodities or stocks, is that you can profit from falling markets as well. Remember, a CFD is a Contract for Difference, but that difference can go in any direction. So you can invest in the possibility of prices going up (a “buy” or “long” order) or down (a “sell” or “short” order), according to what you think is likely to happen.
