Zero-Investment Portfolio

A portfolio consisting of long positions and short positions with no combined net worth. To give a very simple example, suppose one buys 100 shares in AT&T while simultaneously selling 100 shares; this creates a zero-investment portfolio. A zero-investment portfolio has the advantages of carrying little or no risk and reducing taxes. Obviously, however, there is little or no return on a zero-investment portfolio.
