If you tend to find yourself looking into cash flows and profitability ratios, then you may find this article to be an interesting starting point for your own analysis.

To construct this list we initially found those companies with increasing operating cash flow relative to revenues over the last twelve months (TTM) when comparing against the 3-year and 5-year averages. I.e. TTM operating cash flow greater than 3-year average and 5-year by more than 25%.

We then focused on those names that observed a higher return on equity, on a year-over-year basis, and had an encouraging DuPont breakdown. This implies:

- Improving profit margin, i.e. higher Net Income/ Revenues
- Improving asset turnover, i.e. higher Sales/Assets
- And decreasing leverage ratio, i.e. lower Assets/Equity
