Introduction to Technical Analysis
10. The Dow Theory
The Dow Theory, also known as the Dow Jones Theory, forms an important part of technical analysis. Its principles help traders understand the market better and identify price and volume movements more accurately. This theory was propounded by Charles Dow years ago, even before candlestick charts were invented. Basically, the Dow Jones Theory suggests that the market moves in trends. And understanding this theory can help traders identify market trends, so they can make smarter trading decisions.
The six basic tenets of the Dow Theory
For all its usefulness, the Dow Jones Theory is essentially a simple concept that includes six basic tenets. Let’s get right into them.
Tenet 1: The market discounts everything
This is just what the Efficient Market Hypothesis suggests, remember? According to this tenet, the prices of stocks and indices reflect all available and known information. This means that price trends will move according to the new information that becomes available. Traders can study these price movements to understand how the market is likely to move in the near future.
Tenet 2: The market has three trends
This is perhaps one of the most popular tenets of the Dow Jones Theory. It explains that the market moves in three main trends, as listed here.
These trends are the main movements in the market, and they can last for one or more years. They determine if a market is bullish (moving upward) or bearish (moving downward). For individual traders who make up most of the retail trading segment, it’s generally considered a smarter idea to move with the primary trend instead of against it.
Secondary trends are those price patterns that act as corrective points within major primary trends. They’re generally spread over a period ranging from three weeks to a few months. And they move in the opposite direction of the primary trend. For instance, in a primarily bullish market, you may see a bearish secondary trend for a few weeks before the market picks up again.
Minor trends, as the name signifies, occur over a very short range of time. Often, they only last for a few hours or a few days. These trends are essentially just market noise, and they’re the least reliable patterns if you’re looking for market trends to follow. Minor trends can be in the opposite direction of the primary trend or the secondary trend.
In the above image, notice how the primary trend of the market from July 2017 to July 2018 is on an uptrend (from around 9,450 to around 10,800)? And in-between, we have minor trends that last for a few days or two weeks, at the most. The secondary trend occurs between February 2018 and April 2018, when the market goes downward, against the primary uptrend.
Tenet 3: Market trends have three phases
Whether the market is moving upward or downward, every trend is marked by three phases. These phases are listed here.
- Accumulation phase
- Public participation phase
- Distribution phase
Let’s look at what happens during these three phases.
The accumulation phase
This phase generally occurs right after a steep downtrend, during which many investors and traders lose hope of the prices rising upward. So, although the prices may have touched the lowest possible point for that cycle, buyers remain hesitant to purchase the stock. Because of this, the price of the stock continues to stagnate at low levels.
At this point, astute institutional investors enter the market. They recognize that the market has touched a low, and in a bid to accumulate the stock at such low prices, they begin to purchase large volumes of the stock regularly, over a prolonged period of time. This is what results in the formation of support levels, since the huge volumes of stock purchase by these smart investors kickstarts the sluggish demand and gives the stock price a much-needed upward push.
The public participation phase
Also known as the response phase, the public distribution phase is when short-term traders, who follow technical trends, notice the activity that’s taking place and enter the markets. They begin buying the stock as well, causing a quick rise in the price of the asset. In this manner, a bullish trend is established, which is why this phase is also known as the mark-up phase. This rising trend is generally swift and steep, so a large segment of the public is initially left out of the trading rally.
Soon, the news about the markets becomes generally positive, causing more buyers to enter the trading arena. Analysts and researchers see high price trends, and this eventually increases the public participation in the markets.
The distribution phase
At the peak of the mark-up phase, the price of the stock reaches new high levels. As news of these trends become more publicly available, everybody begins to invest in the stock. Here’s where the smart investors again enter the picture. Contrary to what occurred in the accumulation phase, here, institutional investors start to sell off their holdings systematically. They do so when others in the market are focused on buying.
The supply of the stock thus constantly increases. And whenever the stock price attempts to go past a certain point, the increased sell-off from institutional investors prevents it from rising past that mark, leading to the formation of resistance levels. Eventually, the huge sell-off stagnates the price at certain levels and keeps it from rising further. And then, a downtrend begins, leading to a bear market.
In the image below, notice how the market is on a primarily downward trend from January 2000 to around August 2001? Then, nearabout September 2001, there’s a panic price action point after which the institutional investors come in, making the period from around January 2002 to May 2003 an accumulation phase. Notice how there are many support levels that are formed in this phase.
Then, in the response phase, as short-term traders throng to the markets, we see a sharp rise in the index price from around 900 during May 2003 to around 2000 during January 2004. At this point, there’s a resistance that builds up since institutional investors start to sell off their holdings, leading to the formation of a distribution phase.
Tenet 4: The indices must confirm each other
To identify that a trend has been established, it’s essential that all the market indices must confirm each other. So, the movement of one index must match the movement of all other indices in the market. Only then can we label the market as being bullish or bearish, as the case may be.
For instance, say the CNX NIFTY is primarily moving in the upward direction, but NIFTY 500, CNX NIFTY Midcap, and many other indices in the market are primarily moving downward. In this case, it wouldn’t be right to classify the market as bearish (moving downward), since CNX NIFTY is moving up instead. Only when all the indices move in the same direction can you identify the trend concretely, according to the Dow Theory.
Tenet 5: The trading volume must conform with the price trends
According to this tenet, any primary trend in the market, whether upward or downward, must be supported by a corresponding increase in the trading volume. To make it clearer, let’s take the example of a market phase where the prices are on the rise. In order to classify this as a primarily bullish market, the trading volumes should increase when the prices go up (since this is the primary trend) and fall when the prices go down (since this is the secondary trend). In other words, more trades should be following the primary upward trend rather than the secondary downward trend.
Conversely, let’s take a market where the prices are falling. Here, to classify this as a primarily bearish market, the trading volumes should increase when the prices go down (since this is the primary trend) and fall when the prices go up (since this is the secondary trend). In other words, more trades should be following the primary downward trend rather than the secondary upward trend.
In the image above, see how the trading volume rises even as the price falls, and how the volume decreases when the price rises? This shows that a higher number of trades are following the downtrend, pointing to a bearish market.
Trend 6: Trends persist until there is a clear reversal
Charles Dow recognized that it’s easy to confuse secondary trends with trend reversals. This is because both these price movements move in a direction that’s opposite to the primary trend. For instance, say the market is now primarily bearish (or falling downward). A temporary upswing may seem like a trend reversal. But then again, it could also just be a secondary trend. So, as the Dow Theory says, you’ll have to continue to consider the market as bearish even with a temporary upswing until it’s clear that the upward movement is established. In that case, it would be a trend reversal, making the market bullish.
How is the Dow Theory useful for traders?
The Dow Theory primarily helps traders identify market trends with greater accuracy, so they can take advantage of potential price action points. It also helps traders act with caution and not move against the market trends. And above all, the Dow Theory stresses on the importance of the closing price as a good indicator of the general sentiment of the market.
This is because throughout any trading day, trades can happen all over the place. But as the closing bell draws nearer, most market participants will want to conform with the trend. Accordingly, the closing price of a stock is determined, depending on how the traders react as the trading day draws to a close. This can give you a great deal of insight into where the market is heading collectively. With these inputs, you can even develop Dow Jones trading strategies that help you make well-informed trading decisions.
Well, this brings us to the end of our introduction to technical analysis. Now, it’s time to look at one particular segment of the financial markets - the derivative segment. As you’ll recall from our earlier modules, here’s where options and futures are traded. Check out the chapters in our next module to learn all about futures, call options, and put options.
