Specific types of baskets
Certain specific products can be seen as specialized "baskets".
Index funds are a basket for all the securities in a particular exchange, weighted appropriately.
Market baskets are baskets for all the securities on a particular market, weighted appropriately.
It's important to distinguish between true baskets, in which the derivative depends only on the total price of the basket, and multi-underlying derivatives, in which the derivative depends on individual components (for example, a first-to-default basket swap).
Baskets are always traded over-the-counter, but that doesn't mean you can enter into a deal through an agent or broker.
I have never personally seen a basket in the narrow sense of derivatives, that is a security that pays off based solely on the return of a portfolio of derivatives.
