For example, the November 30, 2016 MSCI Factsheet shows that performance of the S&P 500 ESG Index, weighted to account for each S&P 500 companies' ESG Factor Score (assessed by RobecoSAM, a sustainable investment specialist) but restricting sector weightings to be in line with S&P 500, has outperformed the S&P 500 by 293bps annualized since inception (3/31/2009 to 11/30/2016). ESG indices have also provided better risk resilience: the maximum drawdown period of the MSCI KLD 400 Social Index, one of the first SRI indices to incorporate ESG criteria, was 53.7% during the 2009 crisis. In comparison, MSCI USA IMI index, its non-ESG counterpart, witnessed a 55.3% loss during the same time period.
