In plain English
What Index CFD means
An index CFD tracks a market index such as the S&P 500, FTSE 100, or DAX. The contract is cash-settled, so profit or loss is based on the difference between the opening and closing price of the index CFD, adjusted for the contract’s size and any financing charges. It does not give ownership of the shares in the index.
Why it matters
The key distinction is that an index CFD gives exposure to broad market moves without buying the underlying stocks. That changes how the product is priced, how overnight financing works, and what risks apply. It is also different from an index fund or an exchange-traded futures contract, which have different structures and venues.
Example
If an index CFD tracks the S&P 500 at 5,000 and later at 5,050, a long position benefits from a 50-point rise. If the contract size is 1 unit per point, the simplified gross gain is 50 currency units before spread, financing, and any fees. This example is illustrative and simplified.
