The Philosophy of Value Investing and Why It Works

What is Value Investing?

The terms used to describe value investing don't require any accounting or finance background.

Value investing is described as paying 50 cents for a business worth $1. 

Warren Buffett's analogy using the maximum allowable weight of a bridge is used to illustrate how this margin of safety works:

"When you build a bridge, you insist it can carry 30,000 pounds, but you only drive 10,000-pound trucks across it. And that same principle works in investing."




Margin of Safety (buying at a discount) is of utmost importance

What allows value investors to apply a margin of safety while most speculators and investors do not?

Again using a Buffett analogy to illustrate this:

A long-term-oriented value investor is a batter in a game where no balls or strikes are called, allowing dozens, even hundreds, of pitches to go by, including many at which other batters would swing. Value investors have infinite patience and are willing to wait until they are thrown a pitch they can handle—an undervalued investment opportunity.



Value investors do not buy businesses they do not understand, nor ones that they find risky. For example, they will avoid technology companies and commercial banks. 

Value investors will also invest where their securities are backed by tangible assets, to protect them from downside risk.

Because the future is unknown (e.g. a business worth $1 today might be worth 75 cents or $1.25 tomorrow), there is little to be gained by paying $1 for this business.

The margin of safety (buying at a discount) is therefore of utmost importance. 

Value investors gain an advantage when many:

  • do not buy with a margin of safety, 
  • remain fully invested at all times, and 
  • trade stocks like pieces of paper with little regard to the underlying asset values.
