What is Dow Theory? Learn Investment Strategies, Trends, Technical Analysis & Principles of Dow Theory
The Dow Theory is a fundamental principle of technical analysis that is widely used to identify the overall trend of the stock market. It was developed by Charles H. Dow in the late 19th century.
Traders and investors have widely used Dow Theory since then to identify market trends and base investment decisions on them. In this blog, we will take a closer look at the history and origins of Dow Theory, how it works, its pros and cons, and the key principles and trading strategies associated with it.
What is Dow Theory in Stock Market?
Dow Theory is a technical analysis approach to investing. It was developed by Charles Dow, the founder of the Dow Jones and Company. The dow theory was developed to explain the concept that share market moves in trends that can be analyzed and predicted. Dow Jones theory provides a framework for understanding market behaviour and making informed investment decisions.
History and Origin
Charles Dow developed the Dow Theory in the late 1800s along with his business partner, Edward Jones. Together they founded the Dow Jones and Company. It published the Wall Street Journal and created the Dow Jones Industrial Average.
How Does it Work?
Dow theory meaning is based on the idea that the stock market theory moves in three trends: the primary trend, the secondary trend, and the minor trend. The primary trend is the overall direction of the market, which can last for several years. The secondary trend is a correction to the primary trend, which can last for several months. The minor trend is a short-term fluctuation in the market, which can last for several days.
This theory also emphasizes the importance of volume in confirming price movements. If one of the prices are rising in high volume, it is considered to be a bullish sign. On the other hand, if prices are falling on high volume, it is considered to be a bearish sign. Dow’s Theory also emphasizes the importance of trend confirmation. For example, if the Dow Jones Industrial Average and the Dow Jones Transportation Average are both moving in the same direction. It is considered to be a confirmation of the current trend.
Importance of Dow Theory
Charles Dow’s Theory is an important tool for technical analysis in the stock market. The theory has been around for over a century and continues to be relevant today. Here are a few reasons why the Dow Theory is important:
- Understanding Market Trends: The Dow’s Theory helps investors understand the direction of the overall market trend. By analyzing the primary, secondary, and minor trends, investors can make more informed investment decisions.
- Identifying Stock Trends: Dow Theory can help investors identify the trends of individual stocks. By understanding the stock’s trend, investors can make better decisions about when to buy or sell.
- Technical Analysis: The Dow Theory is a key tool in technical analysis. It helps investors identify support and resistance levels, as well as important trend lines.
- Risk Management: Dow’s Theory can help investors manage risk. By understanding the trend of the market, investors can adjust their portfolios to protect against potential losses.
- Long-Term Dow Investing: The Dow Theory is useful for long-term investors who are interested in investing in the stock market. By understanding the long-term trends, investors can make better decisions about which stocks to invest in.
The Three Trends in Dow Theory
There are three Dow Theory trend that are important to understand for analyzing the stock market:
The Primary Trend in Dow Theory
The primary trend is the long-term trend that generally lasts for a year or more. This trend is characterized by a sustained movement in one direction, either upward or downward. It also represents the overall market sentiment.
The Secondary Trend in Dow Theory
The secondary trend is a corrective movement that lasts for several weeks to several months. It moves in the opposite direction of the primary trend and represents a counter-trend movement. However, this trend does not necessarily reverse the primary trend but rather is a temporary pullback or correction.
The Minor Trend
The minor trend is the short-term trend that lasts for a few days to a few weeks. Therefore, this trend moves in the same direction as the primary trend and is often caused by short-term fluctuations in supply and demand.
Note: To understand and explain dow theory, these three trends can be crucial to identifying the current market trend and making informed investment decisions. The Charles Dow Theory suggests that you should only trade in the direction of the primary trend and avoid trading during the secondary and minor trends.
Key Principles of Dow Theory
The Market Discounts Everything
The first principle of Charles Dow’s Theory is that the market discounts everything. This means that all the information about a company or an industry is already reflected in the stock price. Investors can analyze past market data to try to predict future market trends. But ultimately, the market will always reflect all available information.
The market has Three Trends
The second principle of Dow’s Theory is that the market has three trends. These are the primary trend, the secondary trend, and the minor trend. The primary trend is the long-term direction of the market and can last for several years. The secondary trend is a counter-trend movement that lasts several weeks or months, and the minor trend is the day-to-day fluctuations of the market.
Trend Confirmation
The third principle of Dow’s Theory is trend confirmation. This means that a trend is not considered to be valid until it is confirmed by both the Dow Jones Industrial Average and the Dow Jones Transportation Average. According to this theory, if both the Dow indexes are moving in the same direction, it confirms the trend. If they are moving in opposite directions, it indicates a potential reversal in the trend.
Volume Confirmation
The fourth principle of Dow’s Theory is volume confirmation. This means that a trend is more likely to be sustained if there is a high volume of trading activity in the direction of the trend. Low volume during a trend may indicate that the trend is weak and may not be sustained.
Double Bottom and Top Formation
Like in candlesticks, there are few important patterns in Dow Theory as well, one of the dow process patterns is double bottom and double top formation.
A double top and double bottom are recognized as reversal patterns in Dow Jones trading. A double bottom takes place when a stock’s price reaches a modest low and promptly bounces back with a rapid recovery. Subsequent to the price rebound, the stock sustains trading at an elevated level (in relation to the initial low) for a minimum of two weeks, with well-distributed intervals. Following this period, the stock makes an attempt to return to the previously established low. If the stock successfully holds its ground, experiences another rebound, then a double bottom pattern emerges.
The formation of a double bottom is perceived as a bullish signal, indicating potential buying opportunities. Let’s have a look at the dow theory chart to understand this pattern.
Observe the temporal gap between the formations of the two bottom patterns. The pricing levels were distinctly spread out over time.
Pros of Dow Theory
Some advantages of Charles Dow’s theory are as follows:
- Long-term Perspective: Dow Theory is based on long-term market trends. It can provide investors with a big-picture view of market movements. It can also help investors avoid knee-jerk reactions to short-term market fluctuations and focus on long-term growth potential.
- Easy to Understand: This theory is based on simple principles. The theory provides clear guidelines on how to identify market trends, and it can be a useful tool for investors looking to better understand market behaviour.
- Follows Market Trends: The Dow process is based on the idea that the market is always right. And it helps investors follow the current trend. By identifying the trend, investors can make better decisions about when to buy and sell securities.
Cons of Dow Theory
Some cons of Dow’s Theory are as follows:
Not Always Accurate
While the Dow Theory is a useful tool for analyzing market trends, it is not always accurate in predicting future market movements. There are various external factors, such as political and economic events, that can influence market behaviour and make it difficult to rely solely on the Dow Theory.
Ignores Other Important Factors
The Dow process focuses primarily on market trends and does not take into account other important factors that can affect market behaviour, such as company fundamentals, macroeconomic indicators, and industry trends. Therefore, it may not provide a comprehensive picture of the market.
Limited to 30 Stocks
The Dow Jones Industrial Average only includes 30 large-cap stocks, which may not be representative of the entire market. This limited sample size may not accurately reflect the performance of the broader market or certain sectors, which may limit the usefulness of the Dow Theory for some investors.
Dow Theory Trading Strategy
The Dow Theory trading strategy is based on the principles outlined in the Dow Theory. It emphasizes the importance of trend stock analysis in making investment decisions. Here are the key steps involved in using the Dow Theory in trading:
Step 1: Identify the Primary Trend
The first step in the Dow Theory trading strategy is to identify the primary trend of the market. This is done by analyzing the long-term price movements of the market, typically over a period of several months to years. If the market is moving consistently higher, it is said to be in an uptrend, while if it is constantly moving lower, it is in a downtrend.
Step 2: Confirm the Trend
Once the primary trend has been identified, the next step is to confirm it. This involves looking for other indicators, such as trading volume, to confirm the direction of the trend. In general, if trading volume is increasing as the market moves in the direction of the trend, it is seen as confirmation of the trend.
Step 3: Identify Secondary Trends
Within the primary trend, there will be secondary trends that can provide opportunities for traders to enter or exit the market. Secondary trends are typically shorter-term movements within the primary trend, lasting several weeks to a few months.
Step 4: Look for Trend Reversals
One of the key principles of the Dow Jones Theory is that trends tend to continue until there is evidence of a reversal. Traders using this strategy will look for signs that the trend is weakening or reversing. Such as a change in trading volume or a break in key support or resistance levels.
Step 5: Use Dow Theory Technical Analysis
Technical stock analysis plays a key role in the Dow Theory trading strategy. Traders will use charts and technical indicators to identify key support and resistance levels, trend lines, and other patterns that can provide insight into the direction of the market.
Step 6: Implement Risk Management
As with any trading strategy, risk management is critical when using the Dow Theory. Traders should set stop-loss orders to limit their losses in the event the market moves against them, and they should use position sizing and other risk management techniques to manage their exposure to the market.
