To run this back-test accurately I need to nail down a couple of practical details: 1. Market universe • U.S. listed common stocks (NYSE + NASDAQ) – default assumption • Something else? (e.g., a specific country/region, or ADR-filtered universe) 2. • Buy at today’s close, sell at tomorrow’s close (1-day holding period) – default assumption • Equal-weight across the 500 names – default assumption • Zero transaction costs/slippage unless you want to specify some numbers 3. Benchmark / performance metrics (optional) • Compare against SPY? • Particular statistics you care about (e.g., Sharpe, max drawdown)? Let me know if the default assumptions work or if you’d like to change anything. Once they’re confirmed I’ll pull the required data and run the back-test.
