A contract for difference (CFD) is a popular form of derivative trading. CFD trading enables you to speculate on the rising or falling prices of fast-moving global financial markets (or instruments) such as shares, indices, commodities, currencies, and treasuries.
Some of the benefits of CFD trading are that you can trade on margin, and you can go short (sell) if you think prices will go down or go long (buy) if you think prices will rise. CFDs are tax efficient in the UK, meaning there is no stamp duty to pay*. You can also use CFD trades to hedge an existing physical portfolio.
