To run a daily-rebalanced "top-500-by-volume" strategy we need to clarify a few practical points: 1. Universe scope • Is it all U.S. listed common stocks (NYSE + NASDAQ)? • ADRs/ETFs excluded? 2. Weighting / portfolio construction • Equal-weight each of the 500 names, or volume-weighted, or market-cap-weighted? • Rebalance fully every trading day (i.e., sell all yesterday’s holdings and buy today’s list)? 3. Transaction assumptions • Round-trip trading cost / slippage to apply (if any). 4. Tool limitation note The current back-test engine available here evaluates one ticker (index, ETF, or stock) at a time. Running a true cross-sectional portfolio of 500 tickers is therefore not directly supported via a single call. Typical work-arounds are: • Use a composite vehicle that already aggregates a large-cap/high-liquidity basket (e.g., SPY or RSP) as a proxy, or • Narrow the scope to a single security of interest.
