A Key Rate of Sector and Country Diversification

Abstract

The degree of diversification is the most important issue investors should consider when forming portfolios or choosing portfolio managers. This article argues that high-net-worth (HNW) investors can usually do a lot to increase their degree of portfolio diversification, not only with respect to the market risk but also regarding a whole battery of potential risk factors that impinge on the portfolio. In particular, the article suggests a method to determine the degree of industry diversification and country diversification, which may be useful when HNW investors compare portfolios.
