Contracts for Difference (CFDs) are innovative financial instruments that allow investors to benefit from price movements in underlying assets without owning the assets. CFDs were developed in London in the early 1990s as a way for institutional investors and hedge funds to hedge positions on the London Stock Exchange. With a CFD, the buyer and seller agree that the buyer will be paid the difference between the contract value and the asset value at contract close. This allows traders to participate in market gains and losses using only a fraction of the capital required to purchase the underlying asset outright. CFDs can be used to take long or short positions on margin and are traded in over-the-counter markets in many countries around the world.
