Dow Theory( - Beginners Need to Know About Technical Analysis Tools That Still Hold Value

If you are just starting to learn how to analyze the market, the term Dow Theory( should be quite familiar to you. This theory is considered the cornerstone of modern technical analysis, with over a century of history, yet it remains widely applied across various financial markets—stocks, crypto, gold, and other tradable commodities.

Origin and Background of Dow Theory

Dow Theory emerged in the early 20th century, developed from the ideas of Charles H. Dow, founder of the famous The Wall Street Journal. Later, William Peter Hamilton helped expand and connect these ideas into a more complete system.

Although developed long ago, the principles of Dow Theory still form the foundation of )Technical Analysis( used by millions of investors to make trading decisions.

Key Content: What Does Dow Theory Explain?

Before diving deeper, let’s clarify the definition of Dow Theory.

Dow Theory is a tool used to study price movements from the perspective of )market trends( and )business cycles(. It views the market as moving like ocean waves, with peaks and troughs.

The main points are:

• In an uptrend, the length of upward waves exceeds that of downward waves.
• In a downtrend, the length of downward waves is longer than upward waves.

Six Principles Every Investor Must Know

) 1. The Market Reflects All Information

Whether it’s news, price data, corporate earnings, or the overall economic condition—all are reflected in the ###price( visible on the chart.

) 2. There Are 3 Trends Occurring Simultaneously

Primary Trend ###Main Trend(

• Duration: 1 year or longer, sometimes up to 4 years
• The most significant trend for long-term investment decisions

Intermediate Trend )Secondary Trend(

• Duration: 3 weeks to 3 months
• Movements within the primary trend, possibly retracing

Minor Trend )Minor Fluctuation(

• Duration: less than 3 weeks
• Short-term fluctuations on the chart

) 3. Trends Have Buying and Selling Behaviors in Phases

Phase 1 - Accumulation ###Accumulation(

• Institutional investors start buying when prices are low
• The chart shows no clear signals; beginners ignore it

Phase 2 - Public Participation )Public Participation(

• Asset becomes widely discussed
• Trading volume increases, profits come quickly
• The easiest phase for speculators to profit

Phase 3 - Distribution )Distribution(

• Major investors start selling to realize gains
• Beginners get excited by good news and buy
• High risk; discipline needed to cut losses

) 4. Markets Must Confirm Each Other

In Charles Dow’s time, he used the Dow Jones Industrial Average ###Commodity Index( and the Dow Jones Transportation Average )Transport Index( for confirmation.

Meaning: If the stock market is in an uptrend, commodity and transportation indices should also rise. If not aligned, there may be underlying reasons.

) 5. Volume Must Confirm the Trend

When prices rise, trading volume should increase = signals a genuine upward move.

When prices fall, volume should increase = signals a genuine downward move.

If trend and volume do not align, it may warn of a potential trend reversal.

6. Trends Continue Until Clear Signals Indicate Reversal

Prices tend to follow the current trend until a clear sign appears that the trend has changed, such as:

• Making a lower high after an uptrend (Lower High)
• Making a lower low ###Lower Low( for the second time

Difference Between Uptrend, Downtrend, and Sideway

) Uptrend (Uptrend)

• Higher Highs ###Higher Highs = HH(
• Higher Lows )Higher Low = HL(
• Chart moves in ascending order

) Downtrend (Downtrend)

• Lower Highs ###Lower High = LH(
• Lower Lows )Lower Low = LL(
• Chart moves in descending order

) Sideway (Sideways)

• Alternating HH, HL, LH, LL
• No clear direction
• Possibly a consolidation phase before a trend change

Pattern Changes to Watch For

Double Bottom (Two Bottoms)

• Occurs after a prolonged downtrend
• Price hits a low, breaks out, then hits another low
• Signals potential reversal to an uptrend
• Looks like the letter “W”

Double Top (Two Tops)

• Occurs after a prolonged uptrend
• Price hits a high, breaks out, then hits another high
• Signals potential reversal to a downtrend
• Looks like the letter “M”

Note: No technique is 100% accurate; always use judgment and risk management in tandem.
