Method Retirement Extender® uses Modern Portfolio Theory as (MPT) as its primary investing strategy. MPT is an investment strategy whose goal is to maximize investment return for a given amount of risk. MPT believes that by adding additional asset classes to a portfolio (i.e. diversification) long-term returns increase and at the same time year-to-year fluctuations in portfolio value (also known as volatility or standard deviation) are reduced. Additionally, we use Monte Carlo Simulation when creating financial plans for clients. Have a Question Name Email Phone Question Thank you! Oops!
