15. Dow Theory – the grandfather of technical analysis

7 min readUpdated 08 Oct 2026

Almost everything you learned in this module – trends, highs and lows, volume confirmation – can be traced back to one man: Charles H. Dow.

Dow co-founded Dow Jones & Company and was the first editor of The Wall Street Journal in the late 1800s. He never wrote a book on his theory. His editorials were later organised by others, especially William Hamilton and Robert Rhea, into what we now call Dow Theory.

15.1 The six ideas

1. The market discounts everything. All known information is already in the price. (You saw this in Chapter 1.)

2. The market has three trends. - Primary trend – the big tide, lasting months to years. - Secondary trend – waves against the tide, lasting weeks to months. Corrections. - Minor trend – ripples, lasting days.

3. Primary trends have three phases.

Phase In an uptrend Who is active
Accumulation Price is low and quiet; news is still bad Smart, patient money quietly buys
Public participation Price rises steadily; news improves Trend followers join; the big move happens
Distribution / excess Price is high; news is great; everyone is excited Late public buys; smart money quietly sells

4. Indices must confirm each other. Dow compared two indices (industrials and railroads). In today’s India, think: if Nifty makes a new high but Bank Nifty and broader indices don’t, the rally is not fully confirmed.

5. Volume must confirm the trend. Volume should rise in the direction of the main trend. (Chapter 10.)

6. A trend continues until there is a clear signal that it has reversed. Don’t guess tops and bottoms. Wait for the market to prove the trend has changed – for an uptrend, that means a lower high and a lower low.

The three phases at a wedding buffet

At a wedding, the buffet opens at 8 pm. A few smart guests reach the counter first when it is quiet (accumulation). By 9 pm, the main crowd arrives and everyone fills plates (public participation). At 10:30 pm, the latecomers rush in excitedly – just as the caterers start packing up the best dishes (distribution).

Don’t be the 10:30 pm guest in the market.

15.2 Why Dow Theory still matters

The market has changed – computers, algorithms, apps. People have not. Crowds still accumulate quietly, chase loudly and panic together. Dow’s framework helps you ask the right question at any time: Which trend am I looking at, and which phase is it in?

From Karan

When news is super positive and everyone around you – your barber, your cousin, your office group – is talking about stocks, ruk jao aur socho. Maybe you are in the excess phase. When nobody wants to talk about stocks, that is often when the best opportunities quietly form.

Quick check
According to Dow Theory, which phase comes first in a new uptrend?

In accumulation, informed buyers quietly buy while news is still poor and prices are low.

Quick check
Dow Theory says a trend continues until…

Don’t predict reversals. Wait for the market to prove the trend has changed.

Key takeaways from this chapter
  • Dow Theory comes from Charles Dow’s editorials, organised later by Hamilton and Rhea.
  • Three trends: primary, secondary and minor. Primary trends have three phases: accumulation, public participation, distribution.
  • Indices and volume should confirm trends.
  • A trend is in force until a clear reversal signal appears.
  • Ek line mein: Jab sab log stocks ki baat kar rahe hon, ruk ke socho – shayad party khatam hone wali hai.
