What this is. A catalogue, not a guide. Every industry with stocks listed on the NYSE or NASDAQ, the companies contending for its leadership, what each one does according to its own annual report, and the balance sheet it filed with the SEC.

The score runs from 0 to 10 and compares each company with every other one in the almanac on cash generation, profitability, debt, dividends and consistency over the last five years. The higher it is, the better the company fares in that comparison. Curious how much each part weighs? Ask at the bottom of the page.
