6 Main Ideas of Dow Theory
There are six main ideas that support this theory:
Market Price Reflection
Prices reflect all known information, encompassing financial, political, and social factors.
Three Market Movements
These are the primary trend (main market direction), secondary movements (short-term corrections), and daily fluctuations (short-lived and unpredictable).
Phases of Primary Trends
In bullish markets, these phases are accumulation, public participation, and distribution; bearish markets have similar phases in reverse order.
Index Confirmation
Major market indices, like the Dow Jones Industrial and Transportation Averages, must show the same trend for confirmation.
Volume Confirmation
Trading volume should increase with the primary trend and decrease during secondary movements.
Trends Persist
A market trend continues until definitive signals indicate its end.
How the Dow Theory Works
Dow theory works by analyzing the stock market through principles that guide investors in understanding market trends. Here’s a concise breakdown of how it operates:
Analyzing Market Trends
It primarily focuses on identifying the three types of market trends which are primary (long-term), secondary (short-term), and minor (daily) trends. Investors track these trends to determine the overall market direction.
Observing Market Phases
Each primary trend has specific phases. In a bull market, these are accumulation, public participation, and distribution. In a bear market, the phases occur in reverse order. Recognizing these phases helps investors predict trend reversals.
Using Market Indices for Confirmation
The theory stresses the importance of confirmation between major market indices like the Dow Jones Industrial Average and the Dow Jones Transportation Average. A trend is confirmed only when both indices exhibit the same behavior.
Volume Analysis
Volume plays a crucial role. An increase in volume during a trend suggests strength, while a decrease during a corrective phase indicates a weakening trend.
Trend Persistence
It ensures that a trend remains in effect until clear evidence suggests it has ended. This principle helps investors avoid overreacting to minor market fluctuations.
Discounting All News
The theory holds that stock prices reflect all available information, including unforeseen events. Hence, it suggests that analyzing price action is more important than speculating based on news or rumors.
⚠️Tip: Dow theory should not be used in isolation. It should be used with other analysis methods for a well-rounded approach.

Dow theory categorizes market trends into three distinct types, each playing a vital role in understanding overall market behavior.
Primary Trends
Long-term movements lasting over a year indicate the market’s overall direction. They can be bullish (upward) or bearish (downward).
Secondary Trends
Shorter-term trends last a few weeks to months. It acts as a correction to the primary trend. These are opposite to the primary trend and offer short-term trading opportunities.
Minor Trends
Immediate market reactions cause brief, daily fluctuations, which are less significant for long-term market analysis due to their short-lived and unpredictable nature.
