Prime brokerage is the generic name for a bundled package of services offered by investment banks and securities firms to hedge funds and other professional investors needing the ability to borrow securities and cash to be able to invest on a netted basis and achieve an absolute return. The business advantage to a hedge fund of using a Prime Broker is that the Prime Broker provides a centralized securities clearing facility for the hedge fund, and the hedge fund's collateral requirements are netted across all deals handled by the Prime Broker.
