Diversification of a portfolio with appropriate regard for the mathematical formulas in Markowitz portfolio theory. That is, Markowitz diversification occurs when one uses mathematical models to find the securities to place in a portfolio such that the portfolio has the highest possible return for its level of risk. One may engage in Markowitz diversification when one wishes to increase or decrease one's portfolio's risk, or when the portfolio was previously not diversified. See also: Markowitz portfolio theory.
