Difficulties with Ben Graham’s Approach
In a wonderful book, well worth reading, “The Great Investors”, the author, Glen Arnold, writes on the difficulties and drawbacks of Ben Graham’s approach to investing.
“There are some serious difficulties for us in trying to implement a Grahamite investment approach. The first comes from not fully understanding what Ben Graham was saying, or from over-simplifying the technique. For example, not allowing for qualitative factors in net current asset investing.
Torturing the Data
There are a number of derisory terms used in academic circles to describe the process of examining past data for patterns leading to a formula for success – ‘torturing the data until they confess’ is one. Here the ‘researcher’ tries out dozens of formulae on past data until he or she finds the one that gives the desired result. Along the same lines, we have ‘mining the data-set’ until something ‘useful’ is found. The point the academics are making is this: just because you have found some sort of statistical relationship in the numbers you have in front of you, does not mean that it is a reliable relationship upon which you can make decisions about the future; it could be a pure fluke. Alternatively, perhaps it was a reliable relationship in the past, but because so many people are aware of its past existence it no longer exists, because security buyers have acted on new information, and thus the price discounts it. Even Ben Graham’s purely quantitative approach – defensive value investing – has a long list of tests for a stock to pass before it is accepted. Ben Graham goes further; he says this simple approach with its inattention to qualitative factors (e.g. management quality, competitive position of industry and firm, etc.) will produce merely satisfactory results and not the extraordinary returns that investors using simple criteria are looking for.
