Strategic Diversification

At the heart of our investment strategy is an understanding of the advantages of a broadly diversified portfolio. While it's impossible to predict what the market will do on any given day, there are still ways that we can harness its long-term growth and simultaneously protect ourselves from some of the inherent risks of investing. Not only do we put these principles into practice every day in our work with clients, but we also wrote the book on it!

Written by our founder Jeff Martin, Strategic Diversification: Retirement Planning that Works gives you an easy to use road map for retirement saving and investing. It doesn’t matter if you are starting out in your career, or nearing retirement. The book provides a straight-forward method of determining if you are saving enough to live the retirement you envision.

But Strategic Diversification doesn’t stop there. It leads you through an investment approach that has been proven effective during good markets and bad over the past 40 years and updates the approach with the latest research on investing. You will also be educated on how to build and manage your retirement portfolio based on your specific situation, taking into account your investing time horizon, risk tolerance, tax situation and necessary return.
