These moves are seen as critical to maintaining investor confidence in a sector increasingly scrutinized for environmental impact.

I can certainly help structure a back-test for a “Top-500-by-volume” daily-rebalanced portfolio, but a quick clarification is needed before I run the calculations: 1. Universe – should we use all U.S. listed common stocks (NYSE, NASDAQ, AMEX), or some other universe? 2. Price for entry/exit – do you want to assume: • Buy at that day’s close, sell at next day’s close (typical for daily re-balance), or • Buy next day’s open, sell next day’s close? (Please pick one; the default would be “buy today’s close, sell tomorrow’s close.”) 3. Transaction costs / slippage – do we assume zero, or would you like to include a per-trade cost? 4. Equal weighting – should the 500 names be equally weighted each day (default), or value-weighted by volume? Once I have these details I can proceed with pulling the data and running the back-test.
