Resumen de Policy uncertainty and performance characteristics of sustainable investments across regions around the global financial crisis

Hooi Hooi Lean, Duc Khuong Nguyen

• We analyse the performance characteristics of sustainable investments over the period 2004 to 2013. Our unconditional analysis shows that the sustainable portfolios, represented by the Dow Jones Sustainability Indices for the global and three regional markets, experience lower Sharpe ratios than their corresponding conventional portfolios. The conditional analysis indicates some evidence of significant effects of the recent crisis on sustainable investment return and volatility, while the US policy uncertainty only affects returns in two regions (Asia Pacific and North America) during the crisis period. We finally find a relative decoupling of sustainable investing from the overall market system during crisis times.
