With CFDs, you don’t actually purchase or own an instrument, so you are not constricted by the high prices of whole shares. CFDs make it possible to buy or sell part — or a fraction — of a share. For example, if the price of one share of Google stock is $1,000, on eToro you can choose to invest $50 in Google stock with 1:10 leverage, thereby, holding $500 worth of Google stock (half of a share) in your portfolio.
