92 The Business of Value Investing
the long run. These two variables alone represent the critical valuation
metrics of oil companies. While no two businesses can ever be valued
in identical fashion, when it comes to valuing any business, a large
portion of the valuation will hinge on a small handful of variables.
Does this suggest that investors should ignore the little details?
Absolutely not. Serious investment requires a keen knowledge of all
the information. One of the wonderful aspects of investing is that
you are constantly learning something new each day. One business ’ s
negligible data could be another ’ s relevant information. Back to our
oil analogy, in addition to the oil price and production level, you
would also pay attention to production costs. This is helpful as you
begin comparing different oil companies. When the price of oil is
artifi cially high, it would appear that all oil companies are extremely
profi table, thus making management look very competent to share-
holders. Excessively high profi ts based on the price of oil are beyond
the control of management. What management can control, how-
ever, are production costs. And when oil prices decline, oil com-
panies with the right blend of rising production levels and stable
production costs will benefi t while the undisciplined companies hurt.
The point of all this is to expand on the quote of Paul Clitheroe at
the beginning of this chapter: Business valuation is not that hard if
you train yourself to look at the important things over and over.
When the topic of business valuation is discussed in investing
circles, lots of words are thrown around, such as intrinsic value,
margin of safety, free cash fl ow, discount rate, and so on. These are
all very important concepts that are at the core of valuing a busi-
ness. Before getting started in valuing any business, it ’ s important
to have a true understanding of these terms and concepts.
