In plain English
What Underlying asset means
The underlying asset identifies what a CFD is designed to follow. For a share CFD, it may be one company’s shares; for an index CFD, it may be a published equity index; and for a commodity CFD, it may be a spot or futures market reference. A provider’s product specification should state the precise underlying, quote currency, trading hours, pricing source, and any special rules. Similar names can refer to different contracts, so the full specification is important.
Why it matters
Knowing the underlying asset helps a trader understand what events can affect the CFD price and what terms apply. For example, a cash index CFD and a futures-based index CFD can reference the same broad market but have different pricing, expiry, and financing mechanics. It also helps identify whether a dividend, stock split, futures roll, or market closure may require an adjustment.
Example
A provider offers a CFD labeled “US 500.” Its underlying might be a cash equity index or a particular index future, depending on the contract specification. If it is cash-based, the price may be adjusted through overnight financing and dividend treatment. If it is futures-based, the quoted price may instead reflect the selected futures contract and its expiry cycle.
Quick answers
Common questions
Can a CFD have an index as its underlying asset?+
Yes. Many CFDs reference stock indexes, interest-rate benchmarks, commodities, currency pairs, or futures prices. The underlying need not be a single share or a physically deliverable asset.
Why can two CFDs with similar names trade at different prices?+
They may reference different underlying markets, such as a cash index versus a dated futures contract, or use different pricing sources and adjustment rules. Their product specifications may therefore differ materially.
