To run this back-test rigorously I need to clarify a few key points about the investment universe and execution assumptions: 1. Universe • Do we rank every U.S.-listed common stock each day, or restrict ourselves to a subset (e.g., S&P 500 constituents, Russell 3000, China A-shares, etc.)? 2. Execution price • Should we buy the 500 selected names at the same day’s close and exit at the next day’s close (close-to-close return), or buy next day’s open and exit at that day’s close (open-to-close return)? 3. Transaction costs / slippage • Should we assume zero, or include a round-trip cost per trade? 4. Rebalancing frequency • Confirm it is daily rebalancing (every trading day from 2022-01-01 to today). 5. Weighting method • Equal weight across the 500 names each day, or volume-weighted / market-cap-weighted? Once I have these details, I can generate the data-retrieval plan and run the back-test.
