. 10, , , . The move followed a strategic shift in its product development pipeline, with analysts noting improved investor confidence in its long-term growth prospects.

To run this back-test accurately we need to pin down several practical details: 1. Universe – Do you want: • All U.S. common stocks (≈ 4,000+ names), or • A narrower universe such as only primary listings on NYSE/Nasdaq/AMEX, or • Another market? 2. Weights – After selecting the 500 highest-volume stocks each day, should the position be: • Equal-weighted, or • Volume-weighted / value-weighted? 3. Transaction costs – Should we assume zero costs, or include an estimate (e.g., 2 bpBP-- per side)? 4. Overnight gap – The rule “buy and hold for 1 day” can be interpreted as: • Buy at today’s close, sell at tomorrow’s close (close-to-close), or • Buy at today’s close, sell at tomorrow’s open (close-to-open). Which do you prefer? Once you confirm (or let me know reasonable defaults), I’ll pull the necessary close-price and volume data (2022-01-01 to present), run the daily rebalance simulation, and return cumulative & annualized performance metrics.
