January 2018 One of the key drivers of the mass adoption of hedge funds Johanna Kyrklund, CFA Global Head of Multi-Asset was that they provided a source of uncorrelated returns. With Investments asset class valuations increasingly stretched, this need to diversify risk has remained as pressing as ever, but the net of fee results from hedge funds in general have been mixed. In this context, our view is that multi-asset portfolios may provide a cheaper and simpler way of seeking risk-adjusted returns, leaving risk and fee budget for those hedge fund strategies which may genuinely offer uncorrelated returns. Whither diversification? Figure 1: Valuations across asset classes We all know the big picture; after eight years of good % returns and rates pinned close to 0%, valuations are 30 stretched across asset classes.

At this crucial juncture for investors considering how best to diversify, we provide Figure 2: Rolling three-year correlations between an analysis of potential consequences of the changing equities and bonds (local currency terms) dynamics of the hedge fund industry, as well as the return and risk characteristics of hedge funds in the context of 0.8 portfolio diversification. 0.6 0.4 0.2 0 -0.2 -0.4 -0.6 -0.8 1988 1993 1998 2003 2008 2013 Source: Citi, Datastream and MSCI, as at 31 July 2017. 1 When comparing strategies across asset classes, we also like Hedge fund industry dynamics – the times they to use a framework which breaks investment approaches are a changin’… into their major contributing risk factors, providing an One consequence of the increased focus of investors on the assessment in both absolute and relative terms as to what’s use of hedge funds within portfolios has been a change in driving these strategies and what investors should look for the ownership profile of these strategies.
