The act or practice of including securities in different industries in one's portfolio. This is done to reduce systemic risk. For example, if one includes both Industry A and Industry B stocks in one's portfolio, and most Industry A companies go bankrupt, this will not necessarily affect Industry B stocks. Industry allocation thus increases the possibility of making a profit, or at least avoiding a loss. This may also reduce the expected return on a portfolio, but it depends on the level and type of diversification. In general, the broader the industry allocation, the less risk and the less return. See also: Horizontal diversification, Vertical diversification.
