Portfolio diversification measures No single measure of diversification Growing academic literature on measures of systemic risk Need for some definite measures of diversification: Assess current state of the world Observe how it is changing through time We want to consider measures for: Diversification in a given portfolio Diversification potential in an investment universe 6
Measuring diversification different methodologies Principal Components Analysis Breaks down total risk of multi-asset portfolios into independent factors Effective factors answers the question how many factors do you need to explain the risks of the portfolio? uses Entropy principles to determine optimum number Iterative Beta Removal Breaks down the variance of portfolio by underlying componentry of the fund Statistically, this is similar to forward-stagewise regression Entropy techniques again used to determine an optimum number of strategies 7

Defining the investment challenge How can I build a better diversified investment portfolio but without impacting long term return expectations? Allow a broader global investment universe currencies asset classes and sectors yield curves across different geographies volatility A number of these strategies (such as specific currency pairs) will necessitate the use of derivative contracts Allow unconstrained dynamic asset allocation offers access to the full diversification potential of the chosen investment universe 10
