To perform this back-test accurately I need a bit of extra detail, because the tools I can invoke right now work on a single “ticker” (one security / index) at a time. Universe definition: Do you really want the portfolio to comprise 500 individual stocks selected each day, or would an index or ETF that already represents “large, highly-traded” stocks (e.g. S&P 500 or SPY) be an acceptable proxy? If you do want the full 500-stock portfolio, please confirm the market (U.S. equities, global, specific exchange, etc.). Portfolio construction details: Equal-weight each of the 500 names every day and rebalance daily? Any transaction-cost assumption to include? With that clarification I can determine the right data-retrieval and back-testing workflow (or explain alternative ways we can approximate the result with the available tool-set).
