Modern-day Developments
As mentioned, the analysis of businesses and securities has become increasingly sophisticated over the years. Spreadsheet technology, for example, allows for vastly more sophisticated modeling than was possible even one generation ago. Benjamin Graham’s pencil, clearly one of the sharpest of his era, might not be sharp enough today. On the other hand, technology can easily be misused; computer modeling requires making a series of assumptions about the future that can lead to a spurious precision of which Graham would have been quite dubious. While Graham was interested in companies that produced consistent earnings, analysis in his day was less sophisticated regarding why some company’s earnings might be more consistent than others. Analysts today examine businesses but also business models; the bottom-line impact of changes in revenues, profit margins, product mix, and other variables is carefully studied by managements and financial analysts alike. Investors know that businesses do not exist in a vacuum; the actions of competitors, suppliers, and customers can greatly impact corporate profitability and must be considered.
Another important change in focus over time is that while Graham looked at corporate earnings and dividend payments as barometers of a company’s health, most value investors today analyze free cash flow. This is the cash generated annually from the operations of a business after all capital expenditures are made and changes in working capital are considered. Investors have increasingly turned to this metric because reported earnings can be an accounting fiction, masking the cash generated by a business or implying positive cash generation when there is none. Today’s investors have rightly concluded that following the cash— as the manager of a business must do—is the most reliable and revealing means of assessing a company.
In addition, many value investors today consider balance sheet analysis less important than was generally thought a few generations ago. With returns on capital much higher at present than in the past, most stocks trade far above book value; balance sheet analysis is less helpful in understanding upside potential or downside risk of stocks priced at such levels. The effects of sustained inflation over time have also wreaked havoc with the accuracy of assets accounted for using historic cost; this means that two companies owning identical assets could report very different book values. Of course, balance sheets must still be carefully scrutinized. Astute observers of corporate balance sheets are often the first to see business deterioration or vulnerability as inventories and receivables build, debt grows, and cash evaporates. And for investors in the equity and debt of underperforming companies, balance sheet analysis remains one generally reliable way of assessing downside protection.
Globalization has increasingly affected the investment landscape, with most investors looking beyond their home countries for opportunity and diversification. Graham and Dodd’s principles fully apply to international markets, which are, if anything, even more subject to the vicissitudes of investor sentiment—and thus more inefficiently priced—than the U.S. market is today. Investors must be cognizant of the risks of international investing, including exposure to foreign currencies and the need to consider hedging them. Among the other risks are political instability, different (or absent) securities laws and investor protections, varying accounting standards, and limited availability of information.
Oddly enough, despite 75 years of success achieved by value investors, one group of observers largely ignores or dismisses this discipline: academics. Academics tend to create elegant theories that purport to explain the real world but in fact oversimplify it. One such theory, the Efficient Market Hypothesis (EMH), holds that security prices always and immediately reflect all available information, an idea deeply at odds with Graham and Dodd’s notion that there is great value to fundamental security analysis. The Capital Asset Pricing Model (CAPM) relates risk to return but always mistakes volatility, or beta, for risk. Modern Portfolio Theory (MPT) applauds the benefits of diversification in constructing an optimal portfolio. But by insisting that higher expected return comes only with greater risk, MPT effectively repudiates the entire value-investing philosophy and its long-term record of risk-adjusted investment outperformance. Value investors have no time for these theories and generally ignore them.
The assumptions made by these theories—including continuous markets, perfect information, and low or no transaction costs—are unrealistic. Academics, broadly speaking, are so entrenched in their theories that they cannot accept that value investing works. Instead of launching a series of studies to understand the remarkable 50-year investment record of Warren Buffett, academics instead explain him away as an aberration. Greater attention has been paid recently to behavioral economics, a field recognizing that individuals do not always act rationally and have systematic cognitive biases that contribute to market inefficiencies and security mispricings. These teachings—which would not seem alien to Graham—have not yet entered the academic mainstream, but they are building some momentum.
Academics have espoused nuanced permutations of their flawed theories for several decades. Countless thousands of their students have been taught that security analysis is worthless, that risk is the same as volatility, and that investors must avoid overconcentration in good ideas (because in efficient markets there can be no good ideas) and thus diversify into mediocre or bad ones. Of course, for value investors, the propagation of these academic theories has been deeply gratifying: the brainwashing of generations of young investors produces the very inefficiencies that savvy stock pickers can exploit.
Another important factor for value investors to take into account is the growing propensity of the Federal Reserve to intervene in financial markets at the first sign of trouble. Amidst severe turbulence, the Fed frequently lowers interest rates to prop up securities prices and restore investor confidence. While the intention of Fed officials is to maintain orderly capital markets, some money managers view Fed intervention as a virtual license to speculate. Aggressive Fed tactics, sometimes referred to as the “Greenspan put” (now the “Bernanke put”), create a moral hazard that encourages speculation while prolonging overvaluation. So long as value investors aren’t lured into a false sense of security, so long as they can maintain a long-term horizon and ensure their staying power, market dislocations caused by Fed action (or investor anticipation of it) may ultimately be a source of opportunity.
Another modern development of relevance is the ubiquitous cable television coverage of the stock market. This frenetic lunacy exacerbates the already short-term orientation of most investors. It foments the view that it is possible—or even necessary—to have an opinion on everything pertinent to the financial markets, as opposed to the patient and highly selective approach endorsed by Graham and Dodd. This sound-bite culture reinforces the popular impression that investing is easy, not rigorous and painstaking. The daily cheerleading pundits exult at rallies and record highs and commiserate over market reversals; viewers get the impression that up is the only rational market direction and that selling or sitting on the sidelines is almost unpatriotic. The hysterical tenor is exacerbated at every turn. For example, CNBC frequently uses a formatted screen that constantly updates the level of the major market indexes against a digital clock. Not only is the time displayed in hours, minutes, and seconds but in completely useless hundredths of seconds, the numbers flashing by so rapidly (like tenths of a cent on the gas pump) as to be completely unreadable. The only conceivable purpose is to grab the viewers’attention and ratchet their adrenaline to full throttle.
Cable business channels bring the herdlike mentality of the crowd into everyone’s living room, thus making it much harder for viewers to stand apart from the masses. Only on financial cable TV would a commentator with a crazed persona become a celebrity whose pronouncements regularly move markets. In a world in which the differences between investing and speculating are frequently blurred, the nonsense on financial cable channels only compounds the problem. Graham would have been appalled. The only saving grace is that value investors prosper at the expense of those who fall under the spell of the cable pundits. Meanwhile, human nature virtually ensures that there will never be a Graham and Dodd channel……
The real secret to investing is that there is no secret to investing. Every important aspect of value investing has been made available to the public many times over, beginning in 1934 with the first edition of Security Analysis. That so many people fail to follow this timeless and almost foolproof approach enables those who adopt it to remain successful. The foibles of human nature that result in the mass pursuit of instant wealth and effortless gain seem certain to be with us forever. So long as people succumb to this aspect of their natures, value investing will remain, as it has been for 75 years, a sound and low-risk approach to successful long-term investing.
