Standard question: run a specific query on a stock index (Russell 3000/S&P 500, etc...)
1. Go to Mergent and choose advanced search
2. Select Index on the far right
3. Add as many other parameters as you want (profits, sales, other financials)
Get results from that index that meet that criteria.
Or you could generate a list for 1 or 2 attributes for all of the companies on the index.
