Competitiveness and MOAT

High margins render the company resilient under dire circumstances, hence able to drive competitors out or acquire them. ROE and ROA measure the average flow generated by each invested dollar. Their marginal value is a forecast of future growth, and it is considered by Buffett and Munger the most important single indicator.

Net Margins (8.3%)

Net Margins are at a level that is not too high nor too low. They are not a competitive advantage but they are not a competitive disadvantage either.

Safety and Stability

Being debt the number one cause of investment losses and company death, the ratio Debt/FCF is of utmost importance to guarantee safety. On the other hand the Graham’s stability measures the drawdown of earnings, hence indicating the reliability of the flow generated by the company.

Growth Stability	-	-	-	100%	100%	100%	100%	66%	59%	69%	59%

Bad Debt/FCF ratio (5.55)

Good Debt/Equity ratio (0.84)

The company is not overleveraged and has a good balance between equity and debt.

Bad Graham’s Stability (59%)

The company has a bad stability in its earnings, which is a sign of a bad competitive advantage.

Growth

Growth can be dangerous when forecasting, simply projecting the current growth is in general wrong. A company passes through multiple phases, from being young and unprofitable, to the first periods of profitability and high growth, until it arrives at a period of regime with limited growth. Identifying in which phase the company is in may help forecasting.
