Dow Jones Theory, Elliot Wave Theory

Dow Jones Theory

Dow Theory (Dow Jones Theory) is a trading approach developed by Charles Dow.

Dow Theory is the basis of technical analysis of financial markets. The basic idea of Dow Theory is that market price action reflects all available information and the market price movement is comprised of three main trends.

The Averages Discount Everything.

Every knowable factor that may possibly affect both demand and supply is reflected in the market price.

The Market Has Three Trends.

According to Dow an uptrend is consistently rising peaks and troughs. And a downtrend is consistently rising lowering peaks and troughs.

Dow believed that laws of action and reaction apply to the markets just as they do to the physical universe, meaning that each significant movement is followed by a certain pullback.

Dow considered a trend to have three parts:

  1. Primary (compared to tide, reaching further and further inland until the ultimate point is reached).
  2. Secondary (compared to waves and representing corrections in the primary trend, normally retracing between one-third and two-thirds of the previous trend movement and most frequently about half of the previous move)
  3. Minor (ripples) (fluctuations in the secondary trend).

Major Trends Have Three Phases.

Dow mainly paid attention to the primary (major) trends in which he distinguished three phases:

  • Accumulation phase: The most astute investors are entering the market feeling the change in the current market direction.
  • Public participation phase: A majority of technicians begin to join in as the price is rapidly advancing.
  • Distribution phase: A new direction is now commonly recognized and well hiked; economic news are all confirming which all ends up in increasing speculative volume and wide public’s participation.

The Averages Must Confirm Each Other.

Dow used to say that unless both Industrial and Rail Averages exceed a previous peak, there is no confirmation of inception or continuation of a bull market. Signals did no have to occur simultaneously, but the quicker one followed another – the stronger the confirmation was.

Volume Must Confirm the Trend. 

Volume increases or diminishes according to whether the price is moving in direction of a trend or in reverse. Dow considered volume a secondary indicator. His buy or sell signals were based on closing prices.

A Trend Is Assumed to Be Contiunous Until Definite Signals of Its Reversal.

The overall technical approach in market analysis is based upon the idea that trends continue in motion until there is an external force causing it to change its direction – just like any other physical objects. And of course there are reversal signals to be looking for.

Elliot Wave Theory

The Elliott Wave Theory was developed by Ralph Nelson Elliott to describe price movements in financial markets, in which he observed and identified recurring, fractal wave patterns.

How Elliott Waves Work

The Elliott Wave principle consists of impulse and corrective waves at its core:

  • Impulse Waves: Impulse waves consist of five sub-waves that make net movement in the same direction as the trend of the next-largest degree.
  • Corrective Waves: Corrective 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.

These 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 might therefore have a long-term bearish outlook with a short-term bullish outlook.

Elliott recognized that the Fibonacci sequence denotes the number of waves in impulses and corrections. Wave relationships in price and time also commonly exhibit Fibonacci ratios, such as ~38% and 62%. 

Other analysts have developed indicators inspired by the Elliott Wave principle, including the Elliott Wave Oscillator, which is pictured in the image above. The oscillator provides a computerized method of predicting future price direction based on the difference between a five-period and 34-period moving average. Elliott Wave International’s artificial intelligence system, EWAVES, applies all Elliott wave rules and guidelines to data to generate automated Elliott wave analysis.
