The Dow Theory, formulated by Charles H. Dow, is one of the foundational theories in technical analysis used in the finance and investment sectors. It posits that the overall market direction can be predicted by analyzing the movements of two specific market averages: the Dow Jones Industrial Average (DJIA) and the Dow Jones Transportation Average (DJTA).
Key Components of the Dow Theory
The Six Tenets of Dow Theory
- The market has three movements: Primary, secondary, and minor trends.
- Market trends have three phases: Accumulation, public participation, and distribution.
- The stock market discounts all news: All information, news, and earnings projections are already reflected in the market prices.
- Averages must confirm each other: Market trends are confirmed when both the DJIA and the DJTA move in the same direction.
- Volume must confirm the trend: Rising market trends should be accompanied by increasing volume.
- Trends persist until a clear reversal occurs: Market trends continue until definitive signals indicate a reversal.
Types of Trends Explained
- Primary Trends: Long-term trends lasting from several months to several years.
- Secondary Trends: Intermediate trends that can last from weeks to months, acting as corrections within the primary trend.
- Minor Trends: Short-term movements spanning from days to weeks.
Historical Context
The Dow Theory emerged from a series of editorials by Charles H. Dow, founder of The Wall Street Journal and co-founder of Dow Jones & Company, in the late 19th and early 20th centuries. The theory has since been refined by various analysts and remains relevant in modern financial analysis.
