Origins and Historical Background of Dow Theory Letters
The Birth of Dow Theory
The story of Dow Theory Letters begins with Charles H. Dow himself, who in the late 19th
century sought to understand and interpret the stock market’s movements. His
observations led to the development of what is now known as Dow Theory—an analytical
framework that emphasizes the importance of trend analysis, volume confirmation, and
market psychology. Although Dow never published a formal treatise, his principles were
later compiled and expanded by his successors, notably William P. Hamilton, Robert Rhea,
and E. George Berneice.
The Emergence of Dow Theory Letters
While Dow Theory as a set of principles was largely disseminated through books and
articles, the concept of Dow Theory Letters emerged as a dedicated communication
channel—periodic newsletters or commentaries that distill Dow’s principles, interpret
market signals, and provide guidance to subscribers. These letters became essential tools
for traders and investors seeking real-time insights into market trends, especially during
the early 20th century when financial markets were becoming more complex and
widespread. Some prominent figures and firms began publishing regular Dow Theory
Letters, offering analysis aligned with Dow’s core ideas but adapted to contemporary
market conditions. These publications often included technical interpretations, trend
confirmations, and forecasts, serving as early forms of what would now be called technical
research reports. ---
Core Principles of Dow Theory
To understand Dow Theory Letters, it is essential to grasp the fundamental tenets of Dow
Theory itself. These principles underpin the analyses and commentary found within such
Dow Theory Letters
6
letters.
1. The Market Discounts Everything
Dow believed that all available information—be it economic data, earnings reports, or
geopolitical events—is reflected in stock prices. Therefore, market movements are the
best indicators of future trends.
2. The Market Moves in Trends
Dow Theory posits that markets exhibit identifiable trends that persist over time: - Primary
trends: Last months or years; fundamental in nature. - Secondary trends: Corrections or
rallies lasting weeks or months. - Minor trends: Daily fluctuations; often noise.
3. Trends Have Three Phases
In primary trends, there are three phases: - Accumulation phase (smart money buying) -
Public participation or markup phase - Distribution or decline phase
4. Confirmation is Essential
A trend is confirmed only when major indices, such as the Dow Jones Industrial and
Transportation Averages, move in tandem, confirming each other’s signals.
5. Volume Matters
Volume should confirm the trend; increasing volume during upward moves supports
bullish trends, while rising volume during declines indicates bearish sentiment.
6. The Trend Is Your Friend
One of the most famous adages, emphasizing that traders should align their positions with
prevailing trends rather than trying to predict reversals prematurely.
7. The Market Has Three Movements
The market exhibits three types of movements—upward, downward, and sideways—each
requiring different strategies. ---
