点差交易使投资者和交易者无需拥有标的证券就能对资产价格方向进行投机。盈利或者亏损取决于投机者的预测，而不是固定几率和事先已经确定收益或者亏损投资。

The 3 Biggest Spread-Betting Companies in the U.K. (CMCX, GCAP)
By Tim Smith | July 22, 2016 — 3:00 PM EDT
Spread betting enables investors and traders to speculate on the direction of an asset’s price without owning the underlying security. The profit or loss is determined by the degree to which a spread bettor predicts an outcome, as opposed to a fixed-odds bet where there is a win/loss outcome and a predetermined payout or loss.
Spread Betting in the United Kingdom
Spread betting is concentrated in the United Kingdom and is regulated by the Financial Conduct Authority (FCA), an independent regulatory body. As of July 2016, United Kingdom citizens are offered spread betting tax concessions. Spread betting is prohibited in the United States, Japan and Australia due to its high level of risk. Investors and traders who are looking for a large spread-betting company may want to explore the following three options.
