Shares vs CFDs vs Spread Betting: The Difference

When people say "trading," they often mean one of three very different things. The choice between them changes what you own, how you're taxed, how much leverage you carry — and how likely you are to lose money.

This is the piece that clears up the biggest source of confusion for a UK or Australian beginner. "Trading shares," "trading CFDs," and "spread betting" sound like variations on one activity. They are not. One makes you a part-owner of a business; the other two are leveraged bets on price where you own nothing. Getting this distinction wrong is how people end up in a high-risk leveraged product believing they bought shares.

Risk warning. CFDs and spread bets are leveraged products that can lose money rapidly. Most retail investor accounts lose money trading them. [VERIFY + DATE: insert the current FCA/ASIC-published share of retail accounts that lose money.]

Where this sits in the trade

This piece sits where the lifecycle in the mechanics forks: at settlement, you either own an asset or you hold a contract about its price. It depends heavily on the leverage that came before it, and its differences are mostly a matter of the protection and tax regime you sit under.

Shares: owning the asset

Buying a share makes you a part-owner of a company. You hold a real asset that can pay dividends and that you can hold indefinitely; your maximum loss is what you paid (a share can go to zero, but no further). Share dealing is usually unleveraged, which makes it the lowest-risk of the three in structure — your outcome tracks the asset one-for-one, without borrowed money accelerating it. What you give up is the ability to easily profit from falling prices and the amplification (for better and worse) that leverage provides.

CFDs: betting on the price, with leverage

A contract for difference (CFD) is an agreement between you and a broker to exchange the difference in an asset's price between opening and closing the trade. You never own the asset. CFDs are leveraged, so a small deposit controls a large exposure, with all the margin-call and liquidation mechanics from the leverage. They let you go long or short easily and trade many markets from one account — and they are precisely the products on which most retail accounts lose money. CFDs are restricted for retail clients in both the UK and Australia, with leverage caps and negative-balance protection.

Spread betting: a UK product with its own rules

Spread betting is, mechanically, another leveraged bet on price movement — you bet a stake per point the price moves — but it is a UK product with a distinctive tax treatment, and it is not offered to Australian retail clients. In the UK it is generally treated like gambling for tax: profits are usually free of Capital Gains Tax and there is no stamp duty, but, by the same logic, losses cannot be offset against other gains. That tax angle is its main appeal to UK traders — but it sits on top of the same leverage risk as a CFD, so the loss reality is identical.

Comparing the three

In plain terms:

Ownership — shares: yes; CFDs: no; spread bets: no.
Leverage — shares: usually none; CFDs and spread bets: yes (capped for retail).
Go short easily — shares: hard/limited; CFDs and spread bets: yes.
UK tax (illustrative, verify) — shares: CGT on gains, dividends taxable, stamp duty on UK purchases; CFDs: CGT on gains, no stamp duty; spread bets: generally no CGT and no stamp duty, but losses not relievable.
Availability — shares and CFDs: UK and AU (CFDs restricted); spread betting: UK only.
Typical risk profile — shares: lowest (unleveraged); CFDs and spread bets: high (leveraged, majority of retail accounts lose).

The jurisdiction lens

This piece is the jurisdiction lens. A UK reader can access all three products; an Australian reader cannot spread bet at all, and faces ASIC's own CFD restrictions. The tax outcomes differ entirely between the two countries and depend on personal circumstances. Nothing here is portable, and nothing here is tax advice — the only safe move is to confirm the treatment for your own country and situation with a locally regulated professional before assuming any of it applies to you.

The case for and against the leveraged products

For. CFDs and spread bets are flexible and capital-efficient: they let you go long or short across many markets from a single account, hedge existing holdings, and (for UK spread betting) do so with a favourable tax treatment. For experienced, well-capitalised traders who understand the risks, they are legitimate tools.

Against. For most retail traders, the leveraged products are where the losses happen — that is not opinion, it is the regulator-published reality. They invite over-trading, they carry financing costs that punish holding, and the leverage that makes them efficient is the same leverage that empties accounts. Owning shares is structurally far less likely to wipe you out, because nothing is borrowed.

No verdict — but the distinction between owning an asset and making a leveraged bet on its price is the most important one in this series.

FAQ

What is a CFD? A contract for difference — an agreement to exchange the change in an asset's price between opening and closing a trade. It's leveraged and you don't own the underlying asset.

What is spread betting? A leveraged bet on price movement, staked per point, available in the UK. UK profits are generally free of Capital Gains Tax and stamp duty, but losses can't be offset — and it carries the same leverage risk as a CFD.

Is spread betting available in Australia? No — it is a UK product and is not offered to Australian retail clients, who use CFDs instead under ASIC's restrictions. [VERIFY at publish.]

Which is safest, shares, CFDs or spread bets? Structurally, shares — they're usually unleveraged, so your loss tracks the asset and is capped at what you paid. CFDs and spread bets add leverage, and most retail accounts trading them lose money.
