Spread betting and CFDs are both leveraged products that enable you to speculate long or short on the price movements of various financial markets.
With spread betting you are betting a certain number of pounds (GBP) per point on the future direction of a market. With CFDs, you are trading a contract in which you agree to exchange the difference in assets price from when you opened your position to when you close it.
Spread betting profits are exempt from capital gains tax, learn more here.
Spread betting is only available to UK residents.
