What it argues
Value Investing: From Graham to Buffett and Beyond is Bruce Greenwald's attempt to update and extend the tradition that Benjamin Graham established. Greenwald, a Columbia Business School professor who taught in the same program that shaped Warren Buffett, argues that the essence of value investing is not simply buying cheap stocks — it is estimating what a business is worth independent of its market price, then buying only when the price offers a significant margin of safety.
The book is organized around three methods of valuation, each applied depending on the nature of the business. The first is asset value: what would it cost to reproduce the firm's assets? This is most relevant for capital-intensive businesses where asset reproduction cost is estimable. The second is earnings power value: what can the business earn in a normalized, sustainable year? The third, and most complex, is growth value: under what conditions does growth actually add value rather than merely increasing sales? Greenwald's key insight on growth is that it only creates value when a company earns returns above its cost of capital — a condition most businesses, most of the time, do not meet.
What it gets right
- 1.
Intrinsic value is what a business is worth to a well-informed private buyer. The goal is to estimate that value, then buy at a significant discount to it.
- 2.
Asset value, earnings power value, and growth value are three distinct estimates that should be calculated separately and compared — not blended arbitrarily.
- 3.
Growth only adds value when a business earns returns above its cost of capital. For most businesses, growth is value-neutral or value-destructive.
