100 The Business of Value Investing
than 3.75 percent. The issue then becomes what rate is appropriate:
5 percent, 10 percent, 15 percent, or something else?
This is when investing becomes part art and part science. If
you use too low a discount rate, then lots of not - so - great businesses
will look cheap relative to the intrinsic value. Use too high a dis-
count rate and every business looks overpriced. While many bril-
liant investors advocate using 10 percent as a discount rate, in no
way should it be the default rate at all times. You have to account
for the riskiness of the cash fl ows. A start - up company could eas-
ily be valued at a 25 percent discount rate while a business like
Coca - Cola could be valued using something less than 10 percent.
You can be comfortable knowing that the world will continue to
drink Coke, and you have decades of cash fl ow generation to back
you up. But if you ’ re trying to value a new restaurant chain, you
have to account for the lack of operating history, future competi-
tive threats, and so on. I wish there were a scientifi c formula for
applying discount rates, but if there were, investing wouldn ’ t be
investing.
The other companion to the discount rate is the growth rate in
the cash fl ows. By now you might conclude that a 10 percent discount
rate for the movie - store example was too low a fi gure. The example
was used to illustrate the signifi cance of intrinsic value and the mar-
gin of safety. Based on the competitive landscape for movie rentals,
however, 10 percent was not an appropriate discount rate, especially
if we are assigning a 10 percent discount to the low - risk investment. A
much higher discount rate would need to be applied in order to get
a more conservative intrinsic value for the movie store.
Ideally if you are investing in a business, you are doing so
because you are confi dent that, over time, the business will be earn-
ing more profi ts and thus generating higher levels of cash fl ow. But
again, projecting cash fl ow growth rates is also an estimate and an
estimate can easily be different from the actual future results.
