The home bias is the observation that investors systematically hold far too many domestic assets, and consequently far too few foreign assets, than is justified by economic models. Ian Cooper, Evi Kaplanis, Richard Portes, and Heĺene ` Rey, developed the theory of and evidence for the home bias phenomenon. This research has had a substantial impact on investment managers (via additional value from increasing the global diversification of their portfolios), and on central banks and regulators (via accounting for the excessive concentration in domestic debt).
Equity investors have twice suffered large losses, known as `drawdowns' on their investments in the last dozen years: in 2001 and 2009. This applies to both individuals and institutions and has had an adverse effect on both individuals' living standards entering retirement and the attitude of individuals to the advantages of long-term asset accumulation. The research of Professor Andrew Clare and Professor Stephen Thomas at City University London has created commercially available investment products that offer superior risk-adjusted returns with a transparent strategy supported by published, peer-reviewed research and which avoid such large losses. They developed a simple `trend following' 'smoothing` technique to create a diversified, developed market equity fund which was launched by WAY Fund Managers in March 2011. At the start of 2013, following the success of this strategy, the researchers launched an investible index, the Cass Trend Master Index, in collaboration with Credit Suisse. This index now forms the basis of several structured products predominantly aimed at institutional investors. In April 2013 the researchers launched another set of investible indices, based on the same investment principles, with Goldman Sachs and Indexx Markets. These focus on single asset classes including equities and commodities.
This case study charts the influence of the Risk On / Risk Off (RORO) paradigm, developed in research at the University of Oxford in collaboration with investment bank HSBC. Since 2008, RORO has had a significant economic impact on HSBC as well as wider impact on the thinking and actions of investors and other global market participants. Having begun as a specialised research tool within HSBC's foreign exchange team, the RORO methodology was publicised in the advice that HSBC supply to a wide range of major fund managers, corporate institutions and central banks. The research has led directly to a change in the way that asset managers think about investment decisions, with consequent impact on the investment and risk management strategies they undertake. RORO is regularly featured in the financial press and is becoming increasingly mainstream, with coverage in national and international media aimed at retail investors.
