To ensure accuracy in performance evaluation, back-testing parameters require clarification: Does the strategy screen the entire U.S. equity universe or focus on S&P 500 constituents? Will the portfolio maintain equal dollar weighting with daily rebalancing? Should transaction costs be factored in, and is 100% capital reinvestment assumed? Establishing these details is essential for generating a benchmarked performance report from January 3, 2022, to the latest close. Confirmation of these parameters will enable precise signal generation and statistical analysis of the strategy’s historical efficacy.
