Objective: Employ a longitudinal study consisting of 298 one-year periods over 25 years to determine the performance results of using ERS’s Predictive Analytics technology compared to the performance of the S&P 500 index in the same periods.

Study Period: 298 one-year periods: 12/1998 through 9/2023, monthly

Sample: 1,500 largest companies by market cap in each period

  • Minimum market cap of $250 million
  • Minimum stock price $1.00

Study Method:

  • ERS assigned each company a Valuation rating at the beginning of each period.
  • Grouped companies into portfolios based on their Valuation ratings in each period
  • Selected the best 50 or best 30 companies in each period by their Valuation ratings
  • Each period has its own set of 50 or 30 stocks – it’s not always the same 50 stocks across all periods
  • Calculated each portfolio’s average return based on each company’s 1-year rate of return
