You can trade CFDs (Contracts for Difference) based on the shares of listed companies without actually owning the underlying shares. When you buy a stock CFD, you’re speculating on the price movement of the stock rather than taking ownership of it. With these stock-based CFDs you have the option to go long (buy) or go short (sell). If you go long and the stock’s price rises, you make a profit; if you go short and the price falls, you profit from that direction.
