To the extent there is one, it most likely derives from psychology, perhaps in part from the Keynesian idea of conventionally anticipating the conventional response, or perhaps from some as yet unarticulated systemic interactions. “Unarticulated” is the key word here: The quasi-mathematical jargon of technical analysis seldom hangs together as a coherent theory. I’ll begin my discussion of it with one of its less plausible manifestations, the so-called Elliott wave theory. Ralph Nelson Elliott famously believed that the market moved in waves that enabled investors to predict the behavior of stocks. Outlining his theory in 1939, Elliott wrote that stock prices move in cycles based upon the Fibonacci numbers (1, 2, 3, 5, 8, 13, 21, 34, 55, 89, . . . , each successive number in the sequence being the sum of the two previous ones). Most commonly the market rises in five distinct waves and declines in three distinct waves for obscure psychological or systemic reasons.

Some of the modern applications of the Golden Ratio, Fibonacci numbers, and fractals reach into areas that are much more down to earth than the inflationary model of the universe. In fact, some say that the applications can reach even all the way into our pockets. A GOLDEN TOUR OF WALL STREET One of the best-known attempts to use the Fibonacci sequence and the Golden Ratio in the analysis of stock prices is associated with the name of Ralph Nelson Elliott (1871–1948). An accountant by profession, Elliott held various executive positions with railroad companies, primarily in Central America. A serious alimentary tract illness that left him bedridden forced him into retirement in 1929. To occupy his mind, Elliott started to analyze in great detail the rallies and plunges of the Dow Jones Industrial Average. During his lifetime, Elliott witnessed the roaring bull market of the 1920s followed by the Great Depression.

When Nav created his online alter ego, he was a newcomer to trading, twenty-four years old and still buying and selling individual stocks rather than the index futures that would make him rich. His idiosyncratic way of seeing the world and preternatural confidence, though, were evident from the start. Indeed, his opening gambit on the site was a repudiation of two of the godfathers of trading theory. Ralph Nelson Elliott was a Kansas-born accountant who, in 1938, published a book called The Wave Principle that posited that markets move in discernible and therefore predictable wave formations based on the ebb and flow of crowd sentiment from optimism to pessimism. According to Elliott, while markets might appear to be random, they are in fact governed by recurring patterns grounded, like much in nature, on the Fibonacci sequence.

Bubbles are dramatic—but the tendency of markets to deceive and confuse is an everyday affair. Consider chartists, who try to spot patterns in the market. The sophistication of these techniques varies greatly. Some are mere eyeball hunches: A pattern in an index or price chart looks like one that has happened before, and so you bet the chart will keep moving in the same way. Others are more elaborate. The best-known example is the Elliott Wave. Ralph Nelson Elliott was a Kansas-born accountant who spent much of his working life reorganizing railroads and state finances in Central America and who, during a debilitating illness, devised a new charting methodology. Investor psychology, he felt, moves in waves of optimism and pessimism; and these waves can be seen in the stock market again and again, at different times and at different time-scales. His theories gained attention in the 1930s, when he correctly predicted a few market turns, and public interest in them revived in the 1980s.

Nor did the economists using fractals manage to protect their banks and brokerages from the systemic effects of bad mortgage packages, overleveraged European banks, or the impact of algorithmic trading on moment-to-moment volatility. More recently, in early 2010, the world’s leading forecaster applying fractals to markets, Robert Prechter, called for the market to enter a decline of such staggering proportions that it would dwarf anything that has happened in the past three hundred years.16 Prechter bases his methodology on the insights of a 1930s economist, Ralph Nelson Elliott, who isolated a number of the patterns that seem to recur in market price data. They didn’t always occur over the same timescale or amplitude, but they did have the same shape. And they combined to form larger and larger versions of themselves at higher levels, in a highly structured progression. Prechter calls this progression the Elliott Wave. We may as well call it fractalnoia. For not only is the pattern supposed to repeat on different scales and in progressively larger time frames; it’s also supposed to be repeating horizontally across different industries and aspects of human activity.

The equity reduction in an account. The maximum drawdown is the largest difference between a relative equity peak and any subsequent equity low. Low drawdowns are a desirable performance feature for a trader or a trading system. Earnings per share (EPS). A company’s total after-tax profits divided by the number of common shares outstanding. Elliott Wave analysis. A method of market analysis based on the theories of Ralph Nelson Elliott. Although relatively complex, the basic theory is based on the concept that markets move in waves, forming a general pattern of five waves (or market legs) in the direction of the main trend, followed by three corrective waves in the opposite direction. One aspect of the theory is that each of these waves can be broken down into five or three smaller waves and is itself a segment of a still larger wave.

Later, the experimenters told the subjects of the deceit. Even with such clear discrediting evidence, the subjects continued to believe, to a considerable degree, that they were able to discriminate real from fake suicide notes. Other experiments conducted along similar lines have found the same effect: a belief can survive a total discrediting of its original basis.93 These ﬁndings predict how believers might react if Ralph Elliott, W.D. Gann, or Charles Dow were to return from the grave and announce that their methods had been intentional scams. It is likely that many currentday practitioners would continue to believe. Given that Elliott wave analysis, or at least one version of it, has now been reduced to an objective algorithm, it will be interesting to see the reactions of EWP believers if objective tests fail.94 Subjective Methods Most Likely to Suffer the Conﬁrmation Bias Some subjective TA methods are more likely to encourage the conﬁrmation bias than others.
