36 The Business of Value Investing
Later, in 1949, Graham published the The Intelligent Investor , a
much shorter yet equally effective text on the practical principles of
sound investing. It was Security Analysis for a more general audience,
although the book became much more than that. The core theme
of The Intelligent Investor hinged on the distinction between invest-

An investment operation is one which, upon thorough analysis,
promises safety of principal and an adequate return. Ope rat-

thorough analysis, safety of principal, and an adequate return.
I think most investors would agree that satisfying these three condit-

you invest in. In Chapter 11 , I will discuss why growth investing and
value investing are merely two sides of the same coin. Part of the
value in any investment is the growth potential of the business. Ben
Graham came along and taught us how to value this future growth
and use those principles in paying sensible prices for the stock
today. As you will read throughout this book, a major determinant
between a successful investment and an unsuccessful investment is
the price you pay.
Ben Graham ’ s most famous disciple was Warren Buffett, who
today is undeniably considered as the world ’ s most successful and

control of Berkshire Hathaway — at the time a Massachusetts textile
business — to 2007, Berkshire Hathaway ’ s book value per share grew
at an annual compounded gain of 21.1 percent. 2 Buffett took the
fundamentals that Graham had taught him and adapted them over
the years to produce the most successful long - term track record in
modern - day investing. It should come as no surprise that many pro-
fessional investors who want to follow Graham ’ s philosophies and
