Elliott Wave Principle: Key to Market Behavior

by A. J. Frost and Robert R. Prechter Jr.

Quick Summary

This foundational text on the Elliott Wave Principle explains Ralph Nelson Elliott's discovery that stock market prices move in recognizable, repetitive wave patterns reflecting crowd psychology. The book covers the five-wave motive pattern, three-wave corrective patterns, wave degree, Fibonacci relationships, ratio analysis, and practical application of wave counting to real-time markets. It remains the definitive reference for the Elliott Wave analytical framework.

Detailed Summary

Frost and Prechter's "Elliott Wave Principle" is the standard reference for understanding and applying R.N. Elliott's theory that financial markets unfold in recognizable patterns driven by the natural rhythms of crowd psychology.

The early lessons establish the basic tenets. Market progress takes the form of five waves in the direction of the main trend (motive waves labeled 1-2-3-4-5), followed by three corrective waves against the trend (labeled a-b-c). This eight-wave cycle then becomes a single wave of the next higher degree, creating a fractal structure where the same patterns repeat at all scales, from minute-by-minute to century-long movements.

The book distinguishes between two wave modes: motive (which drives the market in the direction of the larger trend and subdivides into five waves) and corrective (which moves against the larger trend and subdivides into three waves). Crucially, the mode is determined by relative direction, not absolute direction -- motive waves can point downward and corrective waves upward, depending on the larger trend context.

The motive wave section covers impulse waves (the standard five-wave advance) and diagonal triangles (five-wave structures with overlapping waves that occur in specific positions). The corrective wave section is extensive, covering zigzags (sharp corrections), flats (sideways corrections), triangles (contracting and expanding), and complex combinations (double and triple zigzags, double and triple threes). Corrective patterns are more varied and more difficult to identify in real time than motive patterns, and the book devotes considerable attention to this challenge.

The Fibonacci section explains Elliott's discovery that wave relationships conform to Fibonacci ratios (0.618, 1.618, 2.618, etc.). Wave 2 typically retraces 0.618 of wave 1. Wave 3 is often 1.618 times wave 1. Wave 4 typically retraces 0.382 of waves 1-3. These ratio relationships provide price targets and help confirm wave counts.

The historical analysis chapters apply the Wave Principle to the entire history of the US stock market, from the late 1700s through the 1970s (when the book was written), demonstrating how the theory explains decades of market behavior. The authors argue that the long-term wave count in the 1970s pointed to a massive bull market ahead -- a prediction that proved spectacularly correct.

The book also discusses the philosophical implications of the Wave Principle: that social mood drives social events (not the reverse), that markets are not random, and that the fractal nature of market patterns reflects deep mathematical principles found throughout nature (the Fibonacci sequence, the golden ratio).

This is essential reading for anyone who wants to understand or use Elliott Wave analysis, though practitioners should be aware that wave counting in real time involves considerable ambiguity and subjective judgment.
