“Who’s short?” is one of the favorite questions asked by risk managers. If traders have a money-making strategy, for example, some person or entity is paying them. Some traders think of the money-supplier as their victim, but this is generally a bad idea. Risk managers prefer to cast that entity as the customer. You want to know your customers, and to serve them better so they will pay you more. You want them to survive and grow, and you want to outcompete others offering a service similar to yours.
