A hedge is a tool used to limit exposure to investment losses. For example, an investor who has large, unrealised profits in a physical stock or stock Options position might sell a CFD for the same stock to prevent any loss of the profits. While the hedge ensures profit in this case, it also ensures that the profit cannot grow. In other words, when you hedge you limit your profits as well as your losses.
