# Elliott Wave

(Redirected from Elliot wave)
 Definition: A theory of price movement cycles which claims that markets follow a pattern of five waves up and three waves down.

## History

Elliot Wave theory was initiated in the 1930s by Ralph Nelson Elliot. His basic theory was that crowd behaviour, the basis for market activity, tends to operate in recognisable phases, and as such, price movements can be anticipated to some degree.

During his early studies, using stock market data for his analysis, Elliot isolated thirteen examples of patterns Ã¢â‚¬â€œ or waves Ã¢â‚¬â€œ that are repetitive in their form only, and that the time and amplitude of the waves need not necessarily be repetitive. To demonstrate what he learned, Elliot named, defined and illustrated each pattern, showing how several small patterns could be brought together to create one larger example of the same form, which would in turn merge into another, larger version of the "wave".

Elliot Wave theory is a collection of these patterns, and a set of guidelines regarding as to where and when the patterns may occur in the financial markets. These patterns allow the Elliot Wave trader to understand market action, and possibly predict future trends. These patterns are now known throughout the industry as "The Elliot Wave principle".

## Application

It is somewhat easier to grasp the concept of Elliot Wave if we demonstrate the theory in pictures, rather than words. The basic format is shown below.

There are two distinct parts to each wave: the numbered phase, and the lettered phase.

In the numbered phase, Waves 1, 3 and 5 are called "impulse" waves - minor upwards moves in an otherwise bullish trend. Waves 2 and 4 are the smaller, less powerful "corrective" waves. Greater volume on impulses than corrections helps confirm the pattern.

In the lettered phase, waves A and C are the stronger impulse waves down, with Wave B Ã¢â‚¬â€œ the bull wave Ã¢â‚¬â€œ now the weaker move.

### Waves within waves

Elliot theorised that the wave above was a small wave, embedded within an overall larger wave, and that each larger wave was in turn simply part of an even larger wave. This can be difficult to imagine, but if we look at the example below, we can see exactly what he meant.

We can see that Waves 1 through 5, and Waves A through C - as shown in the first chart - form part of an overall impulse Wave 3, as shown the second chart above.

### Cycles

Elliot believed that there were many cycles of both impulse and corrective waves, and he named each cycle to fit in with his theory that the waves were based around the Fibonacci series of numbers Ã¢â‚¬â€œ 1, 2, 3, 5, 8, 13 etc. The names are:

1. Grand supercycle
2. Supercycle
3. Cycle
4. Primary
5. Intermediate
6. Minor
7. Minute
8. Minuette
9. Sub-minuette

Elliot provided several varieties of the main wave, and placed particular relevance on the Fibonacci value of 0.618, as the most common level for a retracement to occur. Of course, the examples shown are perfect definitions of Elliot Wave theory. In the real world, things tend not to be quite so clear. The price action shown in the chart below is taken from the NASDAQ Composite Index, during the later part of 2003. The waves are still there, but somewhat harder to spot to the untrained eye.

NB: Wave 1 continues down of the bottom left of the chart so that it's start is lower then the low of wave 2.

In theory, to trade using Elliot is simple. You identify the main wave, enter long, and cover or sell short as a reversal occurs.

In practice, things can be rather different; many wave patterns are identified only with hindsight, and disagreements often arise between followers of Elliot as to which cycle the market is actually in at any given time.

A simpler approach is to add the basic 5-3 wave pattern into your tool box and if it confirms what your methodology indicates (e.g you are thinking of closing a long, you notice that the price has traced a clear five waves up and so EW gives extra confirmation that an exit might be prudent).

• Can be vaguely useful when taken in conjunction with other signal criteria.

• No theoretical basis.
• Extremely subjective. A pattern can easily be force fitted.
• Waves much easier to label with hindsight.

The fact that Robert Prechter - probably the biggest name in Elliott Wave practice - was woefully incorrect in his public stock market predictions during the 1990s was a hit to the technique's credibility as well.
