Backtesting for a strategy involving an equal-weighted portfolio of the top 500 most liquid stocks by dollar volume is currently constrained by platform limitations. The approach requires daily recalculations of volume rankings and rebalancing, which are not yet supported by existing tools. Workarounds include manually submitting daily ticker lists or using proxy indices to approximate performance metrics for the period from January 3, 2022, to October 8, 2025.
