Profitability is not as straightforward as it can appear to be. Although companies report their net income and revenue every quarter and this is what analysts focus on, profitability is a little more nuanced than that. For a deeper look, it's important to find a company's sources of profitability.

By far the most popular tool for this is the DuPont equation. Engineered at DuPont Corporation, this formula takes a company's return on equity (or net income/equity), and breaks it down into three different components:

ROE
= (Net Profit/Equity)
= (Net profit/Sales)*(Sales/Assets)*(Assets/Equity)
= (Net Profit margin)*(Asset turnover)*(Leverage ratio)

Increases in net profit margin and asset turnover are viewed favorably, so their contribution to a rising ROE is also viewed favorably. However increases in the leverage ratio are not a sustainable way to increases profits -- as such, they are not viewed as a "strong" source of profits.

We therefore focus on companies with the following positive characteristics:

Increasing ROE along with:

  • Decreasing leverage, i.e., decreasing Asset/Equity ratio
  • Improving asset use efficiency (i.e., increasing Sales/Assets ratio) and improving net profit margin (i.e., increasing Net Income/Sales ratio)

Companies with all of these characteristics are experiencing increasing profits due to operations and not to increased use of financial leverage.
