4 Dimensions of Risk™

The Bear Market Test: December 2021 – December 2023

On December 31, 2021, ERS rated every U.S. stock above $1 billion in market cap — 2,619 companies in total — using the 4 DIMENSIONS OF RISK™. Each rating group was held equal-weighted for one year and two years. The S&P 500 lost 18.1% in year one and had recovered only 3.4% after two years. The rating predicted not just how far each group would fall — but how much of that loss it would recover.

“A rating that identifies the strongest companies before a bear market is a risk management tool. The A-rated stocks lost less than a third of what the F-rated stocks lost — and then compounded that advantage in the recovery.”

This is a historical study, not a live portfolio or backtest of a single strategy. On 12/31/2021, ERS applied the 4 DIMENSIONS OF RISK™ rating to all U.S.-listed companies with market capitalization above $1 billion, yielding 2,619 companies. Companies were grouped by rating grade (A+ & A, B & C, D, E, and F) using only data available on that date. Each group was held equal-weighted for one year (through 12/31/2022) and two years (through 12/31/2023). S&P 500 returns reflect the index total return over the same holding periods from the same start date. Results do not reflect actual client trading, advisory fees, or transaction costs.
