A proposed involving the top 500 U.S. stocks by dollar volume has sparked discussion among investors. The strategy entails equal-weighted long positions held for one day, with execution at the next session’s open and close. However, practical implementation requires clarification on market universe, transaction cost assumptions, and data constraints. A like SPY or VTI could serve as a proxy, though direct replication of the 500-stock basket remains logistically complex.

Backtesting this approach from January 1, 2022, to the present would necessitate either a predefined index or custom data extraction. While the concept highlights high-volume liquidity opportunities, its feasibility hinges on resolving technical parameters such as market scope and cost estimation. Investors seeking to replicate the strategy must first confirm these details to align with their risk and resource profiles.
