Whilst many use Ben Graham’s models for intrinsic value to evaluate the attractiveness of companies, I don’t. Let me explain why.
Just before I begin though, I want you to know that I am a little nervous about publishing a post advocating against a strict Graham-approach, as it may put a few noses out of joint. So, unlike many of my other posts, I have referenced what I believe to be the pertinent quotes that I have read and that brought me to or reinforced my conclusion that value investors should move on from many parts of Graham’s framework.
In the 1940’s Benjamin Graham (who passed away in 1976) was regarded “as a sort of intellectual dean of Wall Street, [and] was one of the most successful and best known money managers in the country.”[1] In 1949, an eager Warren Buffett read Graham’s book The Intelligent Investor and the rest, as they say, is history.
Warren Buffett regards Graham’s book Security Analysis as the best text on investing, regularly referring investors to that piece and his other seminal The Intelligent Investor. Many of you will also know one of my favourite Graham publications, The Interpretation of Financial Statements.
Yet whilst Buffett remains an adherent and advocate of Graham’s Mr. Market allegory and the Margin of Safety, thanks to his long time partner at Berkshire Hathaway, Charlie Munger, he has moved far from the original techniques taught and applied by the man described as the ‘father of value investing’.
Ben Graham advocated a mostly, if not purely, quantitative approach to finding bargains. He sought to buy businesses trading at a discount to net current asset values – what has been subsequently referred to as ‘net-nets’. That is, he sought companies whose shares could be purchased for less than the current assets – the cash, inventory and receivables – of the company, minus all the liabilities. Graham felt that talking to management was sort of cheating because smaller investors didn’t have the same opportunity.
Whilst the method had been very successful for Graham and the students who continued in his tradition, people like Warren Buffet, Walter Schloss, and Tom Knapp, Graham’s ignorance of the quality of the business and its future prospects did not impress Charlie Munger. Munger thought a lot of Graham’s precepts “where just madness”, as “they ignored relevant facts”.[2]
So while Munger agreed with Graham’s basic premise – that when buying and selling one should be motivated by reference to intrinsic value rather than price momentum, he also noted “Ben Graham had blind spots; he had too low of an appreciation of the fact that some businesses were worth paying big premiums for” and “the trick is to get more quality than you pay for in price.”[3] When Munger referred to quality, he was likely referring to the now common belief held by many sophisticated investors that an assessment of the strategic position of a company is essential to a proper estimation of its value.
In 1972, with Munger’s help, Buffett left behind the strict adherence to buying businesses at prices below net current assets, when, through a company called Blue Chip Stamps, they paid three times book value for See’s Candies.
See’s is a US chocolate manufacturer and retailer – whose product I have purchased and eaten more than my fair share of, whose factory I have toured and whose peanut brittle ranks with the best I have ever tasted.
Buffett noted; “Charlie shoved me in the direction of not just buying bargains, as Ben Graham had taught me. This was the real impact he had on me. It took a powerful force to move me on from Graham’s limiting view. It was the power of Charlie’s mind. He expanded my horizons”[4] and, “… My guess is the last big time to do it Ben’s way was in ’73 or ’74, when you could have done it quite easily.”[5]
So Buffett eventually came around, and the final confirmation, for those still advocating the Graham approach to investing, that a superior method of value investing exists was this from Buffett; “boy, if I had listened only to Ben, would I ever be a lot poorer.”[6]
Times in the US were of course changing as well, and it is vital for investors to realise that the world’s best, those who have been in the business of investing for many decades, do indeed need to evolve. In the first part of the twentieth century industrial manufacturing companies, for example, in steel and textiles, dominated the United States. These businesses were loaded with property, plant and equipment – hard assets. An investor could value these businesses based on what a trade buyer might pay for the entire business or just the assets, and from there, determine if the stock market was doing anything foolish.
But somewhere between the 1960’s and the 1980’s many retail and service businesses emerged that had fewer hard or tangible assets. Their value was in their brands and mastheads, their reach, distribution networks or systems. They leased property rather than bought it. And so it became much more difficult to find businesses whose market capitalisation was lower than the book value of the business, let alone the liquidating value or net current assets. The profits of these companies were being generated by intangible assets and the hard assets were less relevant.
To stay world-beating, the investor had to evolve. Buffet again: “I evolved…I didn’t go from ape to human or human to ape in a nice, even manner.”[7]
Many investors cling to the Graham approach to investing even though some, if not many of his brightest and most successful students, moved on decades ago.
If you are reading this and want to adopt a value investing approach, there is no doubt in my mind that your search for solutions will take you into an examination of the traditional Graham application of value investing. It is my hope, however, that these words will serve as a guide towards something more modern, more relevant and, whilst can’t be guaranteed, more profitable.
If you have tried to adopt the Graham approach and had some successes (or failures) and are keen to share, I would be delighted if you post your own experiences here at my blog.
