There is a lot more to profitability than whether a company's bottom line is growing. Profits can come from several sources, with some better than others. To get a deeper look into a company's profit trends, we performed DuPont analysis on companies reporting their 2011 Q4 earnings next week.
DuPont analyzes return on equity (ROE, or net income/equity) profitability by breaking ROE up into three components:
- (Net Profit/Equity)
- (Net profit/Sales)*(Sales/Assets)*(Assets/Equity)
- (Net Profit margin)*(Asset turnover)*(Leverage ratio)
We therefore focus on companies that have 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.
