Spreadbetting & CFD's.
Spread betting is a derivative strategy, in which participants do not own the underlying asset they bet on, such as a stock or commodity. Rather, spread bettors simply speculate on whether the asset's price will rise or fall, using the prices offered to them by a broker. Contracts 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, such as forex, indices, commodities, shares and treasuries.
Both financial instruments are typically used to make short term trades based on whether you think the price of the asset is going to go up or down.
