If the company has a competitive advantage or disadvantage it is important to account for the company’s earnings power value. The earnings power valuation is quite similar to a standard discounted cash flow valuation, except for a few but important exceptions. Since Greenwald’s valuation model tries to avoid the usage of “bad information” it does not include any forecast period and it does not usually account for growth. Instead, the earnings power valuation relies on the company’s current cash flows. Although the earnings power valuation will be less reliable than the net asset valuation, mainly because it assumes that the current earnings levels will be sustained in eternity, it will be more certain than a present value valuation that relies on forecasts of margins, growth and the cost of capital for many years into the future (Greenwald et. al. [2001]).
