Avoiding Common Stumbling Blocks 231
an investor still hasn ’ t lost any money from the original $ 18 pur-
chase price. These are not scientifi c assumptions, but nonetheless,
they are effective in illustrating the value of growth and why value
investors prize businesses with the ability to maintain sustainable
growth over extended periods of time.
The PEG ratio is considered to be a convenient approximation.
It was popularized by Peter Lynch: “ The P/E ratio of any company
that ’ s fairly priced will equal its growth rate ” — that is, a fairly valued
company will have its PEG equal to 1.^3
Businesses without Current Earnings
The price to earnings (P/E) ratio is generally a sound metric but
can be useless if a business currently has no earnings. The consid-
eration for investment in this instance is not diametrically different
from a company that is actually profi table. Prudent investors realize
that any business can go from being unprofi table to profi table and
vice versa. Obviously since there are no earnings, reliance on the
P/E ratio is out of the question. In such cases, value investors will
expend their efforts on examining the balance sheet, giving care-
ful attention to the assets and assessing whether the business can
become profi table. Even more important is to determine how soon
this profi tability will be achieved and whether that profi tability can be sus-
tained. The extra focus on the balance sheet helps quantify a margin
of safety in case achieving profi tability takes longer than expected
or, in the worst case, profi ts fail to materialize. Paying $ 5 a share
against a company book value of $ 15 a share can minimize capital
loss if a business is forced to liquidate or put itself up for sale.
In many situations, it may be far more advantageous to invest in
temporarily unprofi table businesses, if you are confi dent after rea-
sonable research and analysis that the business will regain and retain
profi tability. Unprofi table businesses may be trading at signifi cantly
depressed prices due to the short - term tendencies of many market
