Benjamin Graham is commonly credited as establishing the discipline of security analysis and being the father of Value Investing. He promoted investment as a rational activity, an approach which requires the investor to return to the financial statements in order to avoid huge mistakes and misjudgments. In his seminal book Security Analysis, published in 1935, Benjamin Graham started sharing his approach and ideas with both professionals and casual investors. He drew a line in the sand between investment and speculation. He defined an investment operation as one which, upon thorough analysis, promises safety of principal and a satisfactory return. Any operations not meeting these requirements are speculative. With the publication of Security Analysis the concept of the Value Investor was born, i.e. someone who seeks to purchase a stock at a bargain price – buying a RAND for fifty cents or put differently buy cheap (or rather good value) and sell dear. One can infer from this that there are times during the market cycle when value investors will have fewer opportunities and times when they will have more opportunities in the market. In short, value investors have more buying opportunities in bear markets than bull markets.

   Toward the latter stages of bull markets value investors find it very hard to find cheap stocks, whereas there are many businesses falling into this classification toward the end of a bear market. Another interesting phenomenon is that it is almost always toward the end of bull markets that investors (or the markets in general) stop paying attention to fundamentals like book value, cash flow, interest, and various other fundamental ratios to value common stock. These are the greedy times as Buffett calls them (and when he is fearful of the markets). Two examples in recent memory springs to mind: the Dot-Com bubble of 2000 and the American Sub-Prime Housing bubble of 2007. In both cases greed and herding resulted in fundamentals being discarded for the more attractive, and at the time more lucrative, new economy thinking. During both these periods it looked as if value investors were an endangered species. This is because proponents of the New Economy hypothesis always argue that some of the fundamental truths of economic reality had been repealed and that value investors’ days are numbered and are being left behind. Value investors’ opinion will be that the market levels are in the tulip mania (see post below) territory, whereas new economy proponents will argue that the good times are here to stay and that markets will keep on rising. Value investors are very patient and therefore not deterred from their approach. They know that the most important thing when employing a decipline is consistent implementation. Therefore, they quietly await the ever looming bear market that will present the perfect time for them to find great buys (i.e. good valuations) at low prices.

   Graham’s original ideas still remain relevant today. Graham’s best known student, or disciple as he likes to refer to himself, is value investor Warren Buffett, whose track record and global fame speaks for itself. Buffett, who had studied different investment theories since the age of 11, says he was struck by the compelling logic of Graham’s approach when he first encountered it. Buffett is by no means the only Graham success story in the world, many other have equally impressive track records, e.g. all the super investors from Graham and Doddsville. Some people refer to Buffett’s approach to value investing as growth-at-a-reasonable-price investing, rather than pure value investing. Buffett's approach is value investing but combined with elements of growth investing, even though Benjamin Graham himself was not a great supporter of valuing and considering potential business growth. In short a growth-at-a-reasonable-price investor buys high quality growth companies when they are experiencing temporary difficulties and have therefore lost favour in the market and thus have an artificially suppressed market price (i.e. buy a RAND for 50 cents).

   Since Security Analysis, and later the Intelligent Investor, many other investment approaches have emerged. During the 1950 and 1960 the very popular modern investment theory, based on rigorous mathematical and statistical analysis and on what’s know as the efficient market hypothesis, emerged. Other investment approaches that emerged include growth investment, momentum investment, technical investment, to name but a few main ones. In the last decade or two behavioural finance emerged. Its been built on psychological research that advocates the idea that investors act based on emotions and other factors, e.g. herding behaviour, the tendency or biases to give more significance to the most recent news, good or bad, etc. Behavioural finance challenges the fact that people are unemotional and always act 100% rational, a premise of the efficient market hypothesis. This finding about excessive reaction confirms a long held Value Investing belief that over the long run, the performance of both businesses and their share prices will revert to the mean. At the core of most investment approaches lies the skill, or art, of business valuation, i.e. the technique by which the real or intrinsic value of a business is estimated. Value Investors want to buy stocks whose true value (per share) is much more that the market price (per share) of the stock, because Value Investors believe that over time the market price will reflect the intrinsic value of the business, i.e. it will revert to the mean as mention above.

   There are many approaches to valuing businesses. There is general agreement that John Burr Williams’ approach,  published as The Theory of Investment Value in 1938, of summing the estimated cash flows a business will produce over its life, and discounting it back to its present value, will yield the value of the business. This is called the discounted cash flow (DCF) approach, present value (PV) approach, or a newer approach called adjusted present value (APV). Then there is the route of multiples, i.e. …. Newer theories, based on option pricing theory, called Real Option Pricing (or Real Options), value businesses like quants value options (for more on Black-Scholes pricing models see Fischer Black and Myron Scholes' 1973 paper The Pricing of Options and Corporate Liabilities). Graham’s approach started with what the business is worth today, rather than to rely only on assumptions about events and conditions far into the future. Therefore, value investors prefer to value a business first by examining the assets of the business, then to look at the earnings power of the business, and if the business shows signs of competitive advantage they value the growth potential of the business via cash flow forecast and DCF analysis.

   Graham’s skepticism of cash flow forecast and valuing growth potential is simply because he believed that in most cases the growth is not worth much. In most competitive environments all the value of the growth will be used to buy additional capital required to enable the growth. Therefore, Graham’s approach only values growth that produces returns in excess of the cost of the additional capital, i.e. a type of economic growth which generally only businesses generating excessive profits achieve. One of Warren Buffett’s well publicized criteria to picking winning investments is that the business, underlying the investment, should have a sustainable competitive advantage, this is because he is looking for the growth stocks at value prices. Businesses with a sustainable competitive advantage are in some way protected, by various forms of barriers to entry (or what Buffett calls a business moat), from competitors entering their market and driving down their excess profits. Therefore, value investors interested in the growth value of a business will pay careful attention to the strategic positioning of the business. Again ahead of its time was that this assessment of the strategic position of a business, now commonplace among the most sophisticated investors, was inherent from the start in Graham’s approach. Next we consider the basic tenets of value investing as well as valuation in a little more detail.
