Here is the link. 


For example, as of March 2019, the iShares Edge MSCI USA Quality Factor ETF holds 125 large- and mid-cap U.S. stocks. By focusing on return on equity (ROE), debt-to-equity (D/E) ratio, and not solely market cap, the ETF has returned 90.49% cumulatively since its inception in July 2013. A similar investment in the S&P 500 Index grew by 66.33%.
