The Elliott Wave Theory  (“EWT”) is named after Ralph Nelson Elliott.

It is a method of technical analysis based on crowd psychology.

Inspired by the Dow Theory and by observations found throughout nature, Elliott concluded that the movement of the stock market could be predicted by observing and identifying a repetitive pattern of waves.

Elliott believed that markets tended to follow a repeating pattern that was driven by crowd psychology.

Regardless of the changes taking place in market conditions, Elliott’s research suggested that investors were ultimately repeating the same boom and bust cycle over and over again.

In fact, Elliott believed that all of man’s activities, not just the stock market, were influenced by these identifiable series of waves.

With the help of C. J. Collins, Elliott’s ideas received the attention of Wall Street in a series of articles published in the Financial World magazine in 1939.

During the 1950s and 1960s (after Elliott’s passing), his work was advanced by Hamilton Bolton. In 1960, Bolton wrote Elliott Wave Principle–A Critical Appraisal. This was the first significant work since Elliott’s passing.

In 1978, Robert Prechter and A. J. Frost collaborated to write the book Elliott Wave Principle.

Today, Robert Prechter has taken up Elliott’s mantle and leads a new generation of so-called “Ellioticians”, applying his theory to today’s financial markets.

High-profile practitioners include Prechter, Jack Schwager, and billionaire Paul Tudor Jones.

How does Elliott Wave Theory work?

The underlying forces behind the Elliott Wave Theory are of building up and tearing down.

Here are the basic concepts of the Elliott Wave Theory:

  1. Action is followed by a reaction.
  2. There are five waves in the direction of the main trend followed by three corrective waves (a “5-3” move).
  3. A 5-3 move completes a cycle. This 5-3 move then becomes two subdivisions of the next higher 5-3 wave.
  4. The underlying 5-3 pattern remains constant, though the time span of each may vary.

The basic pattern is made up of eight waves (five up and three down) which are labeled 1, 2, 3, 4, 5, a, b, and c.

Elliott Wave Theory Pattern

  • Waves 1, 3, and 5 are called impulse waves.
  • Waves 2 and 4 are called corrective waves.
  • Waves a, b, and c correct the main trend made by waves 1 through 5.

The main trend is established by waves 1 through 5 and can be either up or down.

Waves a, b, and c always move in the opposite direction of waves 1 through 5.

Elliott Wave theory understands that public sentiment and mass psychology move in 5 waves within a primary trend, and 3 waves in a countertrend.

Once a 5 wave move in public sentiment is completed, then it is time for the subconscious sentiment of the public to shift in the opposite direction, which is simply a natural cause of events in the human psyche, and not the operative effect from some form of “news.”

A Wave Within a Wave

Elliott Wave Theory holds that each wave within a wave count contains a complete 5-3 wave count of a smaller cycle.

  • The longest wave count is called the Grand Supercycle. Grand Supercycle waves are comprised of Supercycles, and Supercycles are comprised of Cycles.
  • This process continues into Primary, Intermediate, Minute, Minuette, and Sub-Minuette waves.

The following chart shows how 5-3 waves are comprised of smaller cycles.

Elliott Wave Within a Wave

This chart contains the identical pattern shown in the preceding chart, but the smaller cycles are also displayed.

For example, you can see that the impulse wave labeled 1 in the preceding chart is comprised of five smaller waves.

Fibonacci numbers provide the mathematical foundation for the Elliott Wave Theory.

Briefly, the Fibonacci number sequence is made by simply starting at 1 and adding the previous number to arrive at the new number (i.e., 0+1=1, 1+1=2, 2+1=3, 3+2=5, 5+3=8, 8+5=13, etc).

Each of the cycles that Elliott defined is comprised of a total wave count that falls within the Fibonacci number sequence.

For example, the preceding chart shows Waves 1, 3, and 5 are made up of a smaller 5-wave impulse pattern while Waves 2 and 4 are made up of a smaller 3-wave corrective pattern

Elliott Wave practitioners use their determination of the wave count in combination with the Fibonacci numbers to predict the time span and magnitude of future market moves ranging from minutes and hours to years and decades.

There is general agreement among Elliott Wave practitioners that the most recent Grand Supercycle began in 1932 and that the final fifth wave of this cycle began at the market bottom in 1982. However, there has been much disparity since 1982.

Many heralded the arrival of the October 1987 crash as the end of the cycle. The strong recovery that has since followed has caused them to reevaluate their wave counts.

And there lies the weakness of the Elliott Wave Theory. Its predictive value is dependent on an accurate wave count.

Determining where one wave starts and another wave ends can be extremely subjective.

Elliott Wave has been used by some of the most successful traders on Wall Street and totally dismissed by others.
