Within the framework of modern portfolio theory (MPT), the term Markowitz diversification can mean

combining securities with less-than-perfect positive correlation in order to reduce risk in the portfolio without sacrificing any of the portfolio’s expected return.[1]

This approach to diversification was introduced by Harry M. Markowitz in his ground-breaking 1952 paper, Portfolio Selection.[2]

The rationale behind this technique contends that a portfolio constructed of different kinds of investments will, on average, yield higher returns and pose a lower risk than any individual investment found within the portfolio.[3]
