A One-Page Summary Of

Narrative and Numbers

The Value of Stories in Business

The Main Idea

How do you establish the true market value of an asset? This is rather obviously an important question for any investment decision.

One school of thought (left brain) suggests value is driven solely by the numbers and therefore number crunchers can calculate market value with formulas and a spreadsheet. An alternate approach (right brain) is to look at the underlying story or narrative behind the asset and use storytelling to come up with a valuation.A much better approach to valuation is to blend together both the numbers and the underlying narrative. To come up with a good valuation, you have to be able to talk both languages. You have to take the numbers and then give them context on the basis of the background narrative.

Stories without numbers are little more than fairy tails. Numbers without stories are exercises in financial modelling. A good valuation is a bridge which will draw on both the numbers and the stories to come up with a figure that makes sense.

In effect, valuation allows each side to draw on the other, forcing storytellers to see the parts of their stories that are improbable or implausible, and to fix them, and number crunchers to recognize when their numbers generate a story line that does not make sense or is not credible.
