How the Study Was Constructed
The study examined the 2,619 U.S. companies on 12/31/21 with market caps above $1 billion. Each was assigned an ERS 4D rating—A+ & A through F. The forward returns for each group were then tracked over four periods: 6 months, 1 year, 2 years, and 3 years. These returns were compared to the S&P 500 to evaluate how each rating category fared relative to the broader market.
