Dow Theory

Dow Theory

Introduction

The Six Basic Tenets

• Market Averages Discount Everything: This is the most fundamental tenet. All factors – economic, political, psychological – are already reflected in the price.
• The Averages are in an Upward Trend Until Proven Otherwise: This establishes a presumption of bullishness. Trends persist until definitive signals indicate a change. This relates heavily to Trend Following strategies.
• Market Trends Have Three Phases: These phases are Accumulation, Public Participation, and Distribution. Understanding these phases is vital for Swing Trading.
• Old Trends Do Not Abruptly Reverse: Reversals are generally preceded by a period of consolidation or sideways movement. This ties into Chart Patterns.
• Volume Must Confirm the Trend: Increasing volume should accompany advancing prices in an uptrend and declining volume should accompany declining prices in a downtrend. This is a core concept in Volume Analysis.
• The Averages Must Confirm Each Other: This is perhaps the most challenging tenet. The Industrial Average and the Rail Average (originally) should confirm each other's signals. In modern application, this often means comparing different Market Indices.

The Primary Trends

Dow Theory identifies three primary trends:

1. Major Trend: This is the long-term direction of the market, lasting for a year or more. Identifying the major trend is paramount in Position Trading. 2. Intermediate Trend: These trends last from three weeks to three months, representing significant corrections within the major trend. Elliott Wave Theory can sometimes help interpret these. 3. Minor Trend: These are short-term fluctuations lasting days or weeks. Day Trading strategies often focus on these.

Averages and Their Importance

Dow originally focused on two averages: the Dow Jones Industrial Average (DJIA) and the Dow Jones Railroad Average. The principle is that both averages should confirm signals. Today, analysts often use other major indices like the S&P 500 and the NASDAQ Composite (or in the context of crypto, Bitcoin and Ethereum as proxies) to achieve this confirmation.

Signals and Interpretation

Dow Theory signals are generated when a primary trend changes. These are often described as follows:
• Higher Highs and Higher Lows: Indicates an uptrend.
• Lower Highs and Lower Lows: Indicates a downtrend.
• A Break of a Trendline: A crucial signal suggesting a potential trend reversal. This is a core aspect of Support and Resistance analysis.

A significant signal occurs when one average makes a new high (or low) and the other doesn't. This is considered a warning sign. Confirmation happens when both averages confirm the new high (or low).

Trend !! Signal !! Interpretation
Uptrend	! New Highs in Both Averages || Confirmation of Uptrend
Uptrend	! One Average Makes a New High, Other Doesn't || Warning Sign
Downtrend	! New Lows in Both Averages || Confirmation of Downtrend
Downtrend	! One Average Makes a New Low, Other Doesn't || Warning Sign

Limitations and Criticisms

Despite its historical significance, Dow Theory has limitations:
• Lagging Indicator: Signals are often generated *after* a trend has already begun, potentially reducing profitability. This is a common issue with many Indicator-Based Strategies.
• Subjectivity: Interpreting the phases and signals can be subjective, leading to differing opinions among analysts.
• Difficulty in Application to Crypto: Applying the original Dow Theory to the volatile Cryptocurrency Market can be challenging, although it is still used with modifications. Fibonacci Retracements can be used to supplement interpretations.
• False Signals: The theory isn’t foolproof and can generate false signals. Using Risk Management techniques is crucial.
