ERS applied the FIDUCIARY STOCK NAVIGATOR™ to the 1,500 largest U.S. companies by market cap on each of 289 end-of-month dates from December 31, 2000 through December 31, 2024. Every rated stock was tracked for one year and grouped by its rating grade (A+ through F) — producing 433,500 individual data points. In 25 years of data, the rating gradient held without exception: higher grades earned higher returns.

“A rating that separates the highest-return stocks from the lowest — consistently, across 25 years and 433,500 data points — is not a hypothesis. It is documented, reproducible, falsifiable evidence.”
— Raymond M. Mullaney, Founder & CEO, Equity Risk Sciences · 49 years of investment industry experienceThis is a historical simulation, not a live portfolio or backtest of a single strategy. The study covers the 1,500 largest U.S. companies by market cap on each of 289 end-of-month dates from December 31, 2000 through December 31, 2024. On each date, every company received a FIDUCIARY STOCK NAVIGATOR™ rating using only data available on that date. All companies sharing the same rating grade were pooled by date; each position was equal-weighted and held for one year. Returns shown are simple averages across all 433,500 individual ratings in each grade pool. S&P 500 comparisons substitute an equivalent one-year S&P 500 holding for each trade date in the same pool.
