What are the technical differences?

A CFD is a financial derivative that enables you to trade on an asset’s price in the underlying market, without owning the asset itself. It is a leveraged product, meaning you only need to put up a fraction of the full value of the trade – or the ‘margin’ – to gain full exposure. Most CFDs don’t expire, though futures, digital 100s and options do.

When you deal shares, you take ownership of the shares in exchange for their full value. This means there are no underlying markets, no expiry dates and you may gain shareholder privileges. However, you will also pay stamp duty on each trade, and capital gains tax on any profits, except those made via a tax-free stocks and shares ISA or SIPP.1

The differences in detail

  CFD trading Share dealing
What is it? Trading a financial derivative – you deal on prices derived from the underlying market, not on the underlying market itself. The buying and selling of physical shares in a company.
Are there expiries? No expiry dates (excluding forwards, options and digital 100s). No expiry dates.
Do I pay tax?

You don’t pay stamp duty, but you do pay capital gains tax. However, losses can be offset as a tax deduction.

You pay stamp duty on each trade, and capital gains tax on any profits, except those made from trades using a stocks and shares ISA or SIPP.
When can I trade? We offer 24-hour trading on forex and major stock indices. During the underlying market hours for other markets. We also offer weekend trading on selected markets. Only when the related exchange is open.
Do I pay to keep positions open? Overnight funding on all markets, except futures. Rollovers on futures. No.
Does IG profit if I lose?  We profit primarily from commission, spreads and funding, and hedge the majority of net client exposure. We accept a low level of market risk, from which we can make a small profit or loss. The outcome of a client’s DMA trade never has an impact on our profit or loss. We make our money from the commissions you pay on each trade. The outcome of a trade makes no difference to our bottom line.
What kind of trading is it suitable for?






Can I receive dividends? We make a dividend adjustment on equity and stock index CFDs. Yes.
Can it be used for hedging? Yes. Rarely, as other products are more effective.
