approach to valuation - overview

07 October 2012

Greenwald et al contented that company intrinsic value can be determined by careful analysis. It is actually the task that is essential to successful value investors with accuracy to take advantage of the market's mispricing. As we all understand, there are many methods to do so and each method has its own features and benefits.

PV analysis is usually the common approach most finance students should think of when it comes to valuation. But Greenwald et al advocated that the Graham & Dodd approach should be used instead of the common PV analysis. Greenwald et al opinions about the valuation methods are summarized below:

Graham & Dodd approach
PV Analysis
Other methods
(e.g. multiple-based value like EBITDA or sensitivity analysis)
  1. Segregate information affecting valuation by reliability class, so that good info is not contaminated by poor info
  2. Directly uses the valuation implications of broad strategic judgments
  3. Avoid both of the problem found in PV analysis and other methods
  1. Various factors such as more competitions, tech challenges, the rising cost of materials can greatly influence the CF in two or three years
  2. Valuations vary significantly if the underlying assumptions are off by only small amounts
  1. Show similar problems in the opinion of Greenwald et al
  2. The parameters in sensitivity analysis are linked in a complicated way

So, what is Graham & Dodd approach to valuation?

In the approach, there are three essential elements - Assets, Earning Power & Profitable Growth.

Assets

Asset value among the three elements is the most reliable measure in valuing the firm, while the earning power is second and profitable growth is the least reliable measure.

Value investors need to begin with the balance sheet, find the asset value and then find the net asset value by subtracting debt and then arrive at Benjamin Graham famous net-net working capital figures for the company value. For the calculation mentioned above, adjustment needs to be made.

On the other hand, strategic judgment about the company position & its industry is equally important. It can affect the value of assets such as p.p.e. & goodwill and whether these asset items should be valued at reproduction cost. (reproduction cost means the amount the company needs to replace them today.) p.p.e. & goodwill are sometimes taken into consideration in contemporary value investing because nowadays the net-net working capital is a threshold too stringent for finding undervalued stocks in the world.

Earning Power

As for the Earning Power Value (EPV), Graham and Dodd thought that it is the second most reliable measure of a firm's intrinsic value if the current earnings are properly adjusted. Its formula is: 'EPV = adjusted earnings x 1/R', where R is the current cost of capital. To many people, this actually looks like just another multiple-based valuation just criticized. But Greenwald et al argued that this EPV is based entirely on current available information that is uncontaminated by more uncertain conjectures about the future. And, there is a close connection between EPV and its strategic position. I agreed that, compared to the other common valuation models, the EPV calculation relies relatively less on uncertain factors such as growth rate and growth is very hard to be projected. In the EPV calculation, assumption is made that the earning level remains constant for the indefinite future.

Profitable Growth

Difficult growth estimation is one of the reasons why the growth issue is quite isolated from the other two elements into which the more reliable information is incorporated. On the other hand, another reason why growth is least reliable measure actually comes from an interesting argument. Growth on a level economic playing field creates no value. The only growth that creates value is growth in markets where the firm enjoys a competitive advantage. Greenwald et al used the case of WD-40 and Intel to discuss this issue in the book.

three slices of value

Though growth is the element of value that many value investors usually remain skeptical, the other two elements are integrated with it to form a full picture of what a good company should look like. Indeed, these three elements have been covered in great details in the book, particularly including all the adjustments made in the accounting items. Will discuss more about them later.
