How to optimise diversification to improve risk-adjusted returns

The prevailing environment of low interest rates in Europe means that investors cannot rely on government bonds alone for their traditional diversification benefits in a portfolio. They cannot discard the concept of portfolio diversification, though. Rather, they must redefine it to make it fit for purpose in a market where correlations change dynamically.

In this new paper, Legal & General Investment Management’s head of diversified strategies Martin Dietz uses cutting-edge visualisation tools to demonstrate both the subtle relationships that exist between asset classes and the sudden ways in which they can shift. To manage such risks, he highlights three practical ways to embed true diversification within portfolios.
