The Contract for Difference of shares and stocks (CFD) provides a sort of leeway for traders and investors to trade and profit basically on the price movement while not owning the underlining shares and stocks. It’s a kind of financial arrangement you can trade without exchanging ownership of the trading assets.
The transaction between a buyer and a seller on the CFD is based not on the stocks but on the share price movements. In effect, an upward movement of the price of a share during the course of a CFD trading compel the seller to pay the buyer the difference in price, and vice versa when the price of the share goes down.
While there is a momentary change in the value of the share during the trade, the share itself does not change its ownership.
