# Elliott Wave Theory: What It Is and How to Use It

## What Is the Elliott Wave Theory?

Elliott Wave Theory, a cornerstone of [technical analysis](https://www.investopedia.com/terms/t/technicalanalysis.asp), interprets price movements in financial markets through recurrent fractal wave patterns. Developed in the 1930s by Ralph Nelson Elliott, this theory became notable when Elliott correctly predicted a stock market bottom in 1935. The theory helps investors, traders, and portfolio managers detect predictable [market trends](https://www.investopedia.com/articles/technical/03/060303.asp) within stock price movements, thus allowing them to effectively forecast and capitalize on market trends. Elliott outlined specific rules for identifying and predicting these wave patterns in his published works. Notably, the patterns capture investor psychology, underpinning the cyclical nature of market movements, even though they do not guarantee future outcomes.

### Key Takeaways

*   The Elliott Wave Theory, developed by Ralph Nelson Elliott in the 1930s, uses recurring price patterns in financial markets to predict price movements, heavily relying on investor psychology.
*   Elliott Wave analysis is broken down into motive (impulse) and corrective waves, where impulse waves consist of five sub-waves moving in the trend's direction, and corrective waves usually involve three sub-waves moving against it.
*   The theory integrates with Fibonacci ratios to forecast market movements, establishing relationships between wave patterns and numerical ratios like 38% and 62%.
*   Investors and traders use Elliott Wave Theory alongside other technical analysis tools, acknowledging the subjective nature of wave interpretation but leveraging the potential insights into market dynamics and trend patterns.
*   While Elliott Wave Theory aids in anticipating market directions, it does not offer absolute predictions, urging users to combine it with other techniques for a comprehensive analysis.

## History and Development of Elliott Wave Theory

The [Elliott Wave theory](https://www.investopedia.com/articles/technical/111401.asp) was developed by Ralph Nelson Elliott in the 1930s. He studied 75 years' worth of yearly, monthly, weekly, daily, and self-made hourly and 30-minute charts across various [indexes](https://www.investopedia.com/terms/m/marketindex.asp). His theory gained notoriety in 1935 when Elliott made an uncanny prediction of a stock market [bottom](https://www.investopedia.com/terms/b/bottom.asp) and has become a staple for thousands of [portfolio managers](https://www.investopedia.com/terms/p/portfoliomanager.asp), traders, and private investors.

Elliott defined rules to identify, predict, and capitalize on wave patterns in books, articles, and letters summarized in _R.N. Elliott's Masterworks_, published in 1994. Elliott Wave International is the largest independent [financial analysis](https://www.investopedia.com/terms/f/financial-analysis.asp) and market [forecasting](https://www.investopedia.com/terms/f/forecasting.asp) firm whose market analysis and forecasting are based on Elliott’s model.

His patterns do not provide any certainty about future price movement but help to order the probabilities for future market action. They can be used alongside other technical analysis tools, like [technical indicators](https://www.investopedia.com/terms/t/technicalindicator.asp).

## Principles of Elliott Wave Patterns

Some technical analysts profit from wave patterns in the stock market using the Elliott Wave Theory. The theory assumes that [stock price](https://www.investopedia.com/articles/stocks/08/stock-prices-fool.asp) movements can be predicted because they move in repeating up-and-down patterns called waves created by investor psychology or sentiment.

The theory is subjective and identifies two different types of waves: motive or impulse waves, and corrective waves. Wave analysis does not equate to a template to follow instructions. Wave analysis helps investors understand price movements and trends.

Impulse and corrective waves are nested in a self-similar fractal to create larger patterns. For example, a one-year chart may be in the midst of a corrective wave, but a 30-day chart may show a developing impulse wave. A trader with this Elliott wave interpretation may have a long-term [bearish](https://www.investopedia.com/terms/b/bear.asp) outlook with a short-term [bullish](https://www.investopedia.com/terms/b/bull.asp) outlook.

## Identifying Impulse Waves in Elliott Wave Theory

[Impulse waves](https://www.investopedia.com/terms/i/impulsewave.asp) consist of five sub-waves moving in the same direction as the larger trend. This pattern is the most common motive wave and the easiest to spot in a market. It consists of five sub-waves, three of which are motive waves. Two are corrective waves.

*   Wave 2 can’t retrace more than the beginning of Wave 1
*   Wave 3 can not be the shortest wave of the three impulse waves, 1, 3, and 5
*   Wave 4 does not overlap with the price territory of Wave 1
*   Wave 5 needs to end with momentum divergence

If one rule is violated, the structure is not an impulse wave. The trader would need to re-label the suspected impulse wave.

## Understanding Corrective Waves in Elliott Wave Analysis

[Corrective waves](https://www.investopedia.com/terms/c/corrective-waves.asp), called diagonal waves, consist of three, or a combination of three sub-waves that make net movement in the direction opposite to the trend of the next-largest degree.  Their goal is to shift the market in line with the trend.

*   The corrective wave consists of 5 sub-waves.
*   The diagonal looks like either an expanding or contracting wedge.
*   The sub-waves of the diagonal may not have a count of five, depending on what type of diagonal is being observed.
*   Each sub-wave of the diagonal never fully retraces the previous sub-wave, and sub-wave 3 of the diagonal may not be the shortest wave.

## Comparing Elliott Wave Theory to Other Technical Indicators

Elliott recognized that the Fibonacci sequence denotes the number of waves in impulses and corrections. Wave relationships often show [Fibonacci ratios](https://www.investopedia.com/terms/f/fibonaccilines.asp), like 38% and 62%. For example, a corrective wave may have a [retrace](https://www.investopedia.com/terms/d/drawdown.asp) of 38% of the preceding impulse.

Other analysts have developed indicators inspired by the Elliott Wave principle, including the Elliott Wave Oscillator Chart.  The [oscillator](https://www.investopedia.com/terms/o/oscillator.asp) predicts price direction using differences between five- and 34-period moving averages. Elliott Wave International’s artificial intelligence system, EWAVES, applies all Elliott wave rules and guidelines to data to generate automated Elliott wave analysis.

## What Is the Elliott Wave Theory?

In technical analysis, the Elliott Wave theory looks at long-term trends in price patterns and how they correspond with investor psychology. These wave patterns follow rules by Ralph Nelson Elliott developed in the 1930s that help to predict future market movements. 

## How Do Elliott Waves Work?

Based on Elliott's Wave Theory, market prices will alternate between an impulsive phase and a corrective phase. Impulses are always subdivided into a set of 5 lower-degree waves, alternating again between motive and corrective character, so that waves 1, 3, and 5 are impulses, and waves 2 and 4 are smaller retraces of waves 1 and 3.

  

## How Do You Trade Using Elliott Wave Theory?

If a trader sees a stock moving upward on an impulse wave, they may go long until it completes its fifth wave. Anticipating a reversal, the trader may then go short on the stock. This theory is based on fractal patterns recurring in financial markets. In mathematics, fractal patterns repeat themselves on an infinite scale. 

## The Bottom Line

The Elliott Wave Theory was developed by Ralph Nelson Elliott. It provides a technical analysis of price patterns related to investor sentiment and psychology. The theory identifies impulse waves that establish a pattern and corrective waves that oppose the larger trend. It assumes that stock price movements can be predicted because they move in repeating up-and-down patterns.

_Correction—July 27, 2023:_ This article has been amended to state that the third impulse wave can never be the shortest of Waves 1, 3, and 5. This article also previously misstated that Wave 4 cannot go beyond the third wave at any time. The content has been revised to state that Wave 4 does not overlap with the price territory of Wave 1 per Elliott Wave Theory.
