A contract for difference on a share is an agreement between you and your broker to exchange the difference in that share's price between opening and closing. It is not a share. The price may track perfectly, the chart may be identical, and the position may behave exactly as ownership would from day to day — but what you hold is a contract with the broker, not a piece of the company.
The differences that matter
- No ownership: no voting rights, no shareholder communications, no registry entry.
- Leverage is available, and financing is charged on the whole position nightly.
- Dividends are mirrored as cash adjustments, not paid, and are debited on short positions.
- The counterparty is your broker, not a clearing house or a custodian.
What ownership provides that a CFD does not
Holding a share puts your name, directly or through a nominee, on the company's register. That entitles you to vote, to receive shareholder communications, to participate in rights issues on your own terms, and to hold the position indefinitely at no carrying cost. If the broker who executed the purchase fails, the shares are still yours; they are held separately from the firm's own assets and are recoverable.
A CFD provides none of that. The position exists only as an obligation between you and the broker. It cannot be transferred to another provider, it accrues a financing charge every night it is held, and if the broker fails it is a claim in an insolvency rather than an asset in a custody account.
Dividends and corporate actions
When a company goes ex-dividend, its share price drops by roughly the dividend amount. A CFD holder is compensated for that mechanical drop with a cash adjustment: a long position is credited, a short position is debited.
The adjustment is not the dividend. It is usually calculated net of an assumed withholding, it confers no tax credit, and it is booked as a cash entry on the trading account rather than as investment income. For a trader this is immaterial; for someone constructing an income position it is the whole point, and CFDs are the wrong instrument for it.
Other corporate actions — splits, consolidations, rights issues, takeovers — are handled by adjustment at the broker's discretion under the client agreement. In a takeover, positions may simply be closed at a determined price rather than converted. An investor holding the underlying share chooses; a CFD holder is informed.
Short positions pay the dividend
A short share CFD held over an ex-dividend date is debited the adjustment. On a high-yielding share this can exceed several days of financing, and the dividend calendar is not something a price chart shows. Check it before holding a short across the date.
Leverage and the cost of time
This is the practical reason CFDs exist for retail traders. A share position that would require the full purchase price can be opened on a fraction of it, which makes short-term positions in expensive shares accessible. Retail leverage on individual shares is capped at 5:1 in Europe, the UK and Australia; offshore entities offer more.
The cost of that leverage is a nightly financing charge on the full position value, at a benchmark plus a markup. Over days this is negligible against the moves shares make. Over months it is substantial, and over a year it can exceed the dividend yield the position is nominally tracking.
This asymmetry defines the sensible use. CFDs suit positions measured in days or weeks, and short positions where borrowing an actual share would be difficult. Ownership suits positions measured in years.
Counterparty risk
With shares, the broker is an intermediary. With a CFD, the broker is the other side of your trade, and its solvency is part of your position's value. Client money segregation and, where applicable, compensation schemes mitigate this, but they do not remove it, and they operate differently from the custody arrangements that protect share ownership.
This is not an argument against CFDs; it is an argument for treating the choice of provider as part of the position rather than as an administrative detail, and for sizing exposure to a single firm accordingly.
Choosing between them
A short decision procedure
- Write down your intended holding period.
- If it is measured in months or years, price the financing over that period and compare against outright purchase.
- If you need voting rights, shareholder participation or actual dividend income, ownership is the only option.
- If you need to be short, or need leverage on a short horizon, the CFD is the practical instrument.
- Check the tax treatment applicable where you live, since the two are often treated differently.
- Size any CFD position against the broker's failure as well as the market's movement.
Tax treatment deserves the specific mention. Derivatives and share ownership are taxed differently in most jurisdictions, sometimes substantially so, and the difference can outweigh every cost discussed above. It is jurisdiction-specific and worth establishing before rather than after.
Common questions
Do I receive dividends on a share CFD?
You receive a cash adjustment mirroring the dividend on a long position, and pay one on a short. It is not a dividend: it carries no tax credit and is typically net of an assumed withholding.
Can I hold a share CFD long term?
You can, but financing accrues nightly on the full position value and compounds against you. Over a year it commonly exceeds the yield of the underlying share, which is why CFDs suit shorter horizons.
Is a share CFD safer than owning the share?
No. Owning a share gives you an asset held in custody; a CFD gives you a claim against your broker. Market risk is comparable, but counterparty risk exists only in the CFD.
Can I convert a CFD position into actual shares?
No. They are different instruments with different counterparties. Moving from one to the other means closing the CFD and buying the shares separately.
