Risk and Risk Premia : A Cross Asset Class Analysis

The existence of risk premia has been widely documented in the academic literature over the past decades. However, until now they have typically been handled as separate phenomena for specific markets or asset classes and thus examined independently. This study analyses risk premia across a variety of asset classes and risk styles to uncover their common performance characteristics, underlying risk sources and return's sensitivity to economic factors. Based on a set of 16 risk premia over a 22 year sample period we are able to illustrate that risk premia's expected returns are significantly affected by their volatility and their sensitivity to funding liquidity and market volatility. Furthermore we show that macroeconomic factors such as industrial production and inflation have a significant effect on the expected returns of the entire set of risk premia. Finally, analysing the link between premia and the global market portfolio shows that premia with unfavourable comoments possess superior expected returns
