Elliott Wave Theory

What Is Elliott Wave Theory?

Elliott Wave Theory was developed by Ralph Nelson Elliott in the 1930s based on his observation that financial markets move in repetitive, fractal patterns driven by investor psychology. The theory proposes that crowd behavior oscillates between optimism and pessimism in natural sequences, creating identifiable wave patterns on price charts.

The basic structure consists of a five-wave impulse phase (labeled 1-2-3-4-5) that moves in the direction of the larger trend, followed by a three-wave corrective phase (labeled A-B-C) that partially retraces the impulse. This 5-3 pattern forms one complete cycle and exists at every degree of trend, from multi-decade super cycles down to minute-by-minute movements.

The Wave Structure

Impulse waves (1, 3, 5) move with the prevailing trend, while corrective waves (2, 4) move against it. Wave 3 is typically the longest and most powerful impulse wave, often extending to 161.8% of Wave 1. Wave 1 initiates the new trend and is often met with skepticism. Wave 5 is the final push, frequently driven by speculation and retail enthusiasm.

Corrective patterns (A-B-C) come in several forms: zigzags (sharp corrections), flats (sideways corrections), and triangles (converging corrections). Each form has specific Fibonacci ratio tendencies and structural characteristics. Wave 2 tends to be a sharp correction, while Wave 4 tends to be a more complex, sideways pattern, a guideline called alternation.

Practical Application

Many traders use Elliott Wave as a contextual framework rather than a rigid system. Identifying whether the market is in an impulse or corrective phase helps determine the appropriate strategy. During impulse waves, trend-following approaches work best. During corrective waves, range-trading or waiting for the correction to complete is preferred.

Fibonacci relationships are deeply integrated into Elliott Wave analysis. Wave 2 commonly retraces 50% to 61.8% of Wave 1. Wave 3 often extends to 161.8% of Wave 1. Wave 4 commonly retraces 38.2% of Wave 3. These ratios provide specific price targets within the wave framework.
