Contrarian investing and why it works

Definition

What is a contrarian?

A Contrarian makes decisions for different reasons than most traders.

The majority buy out of greed and sell out of panic. As a result, the tendency is to make the wrong decisions.

A contrarian does not simply act contrary to most traders, but tends to not follow the majority if indicators favor the opposite decision.

Contrarian – a trader whose reasons for making trade decisions are based on logic and analysis and not on emotional reaction.

Trading tendencies and market behavior

How most traders trade

Everyone has heard the advice to “Buy low and sell high.”

This sounds easy, and most traders do exactly the opposite. They buy high (greed) and sell low (panic).

A contrarian attempts to “buy low and sell high” by observing how market prices over‐react to news.

The contrarian observation

A contrarian will observe that:

‐most traders follow the majority

‐ the majority is often wrong

‐ as prices rise, a growing number of people tend to buy, and the higher the price, the more buyers

‐ as prices fall, a growing number of people tend to sell, and the lower the price, the more sellers

The contrarian ideal

A contrarian will attempt to:

‐make decisions in spite of what the majority does

‐make a wise decision more often than not, based on analysis and reading of signals

‐ buy when prices are depressed, especially if reversal signals indicate a coming uptrend

‐ sell when prices rise to new heights, especially if reversal signals indicate a coming downtrend

Timing a buy or sell decision

A contrarian not only employs logic and analysis, but also times trades based on:

‐ strong reversal signals found in price patterns, candlestick indicators, volume spikes and momentum oscillators

‐ confirmation of reversals, using the same signals and indicators as reversals; and the stronger the confirmation, the more confidence the contrarian has

‐ avoiding placing too much capital into any single trade, to minimize losses and to avoid large losses

‐ risk reduction methods through hedging and diversification

Price reversal signals

A contrarian will watch trends and look for reversals in the following indicators:

‐ traditional price reversal patterns like the head and shoulders, double tops or bottoms, and price gaps – especially when these appear at or near resistance or support

‐ volume indicators as well as volume spikes, a one‐day or two‐day exceptionally high number of trades

‐momentum oscillators, indicators designed to reveal how quickly trends develop, when they begin to slow down, and when a stock is overbought (a bearish signal) or oversold (a bullish signal)

Contrarians and the efficient market hypothesis

Page 10: Contrarian investing why works - Vanderbilt University · ‐traditional price reversal patterns like the head and shoulders, double tops or bottoms, and price gaps – especially

Definition

The efficient market hypothesis

Contrarians believe that prices can be predicted to a degree, based on the logical and analytical study of market behavior and of the news.

This idea is disputed by EMH, which assumes that the market is efficient and that all information is factored into the price of a stock.

Efficient market hypothesis – the belief that all current prices are based on the accumulation of all known facts and news about the company, meaning that all prices are currently fair and efficient.

Page 11: Contrarian investing why works - Vanderbilt University · ‐traditional price reversal patterns like the head and shoulders, double tops or bottoms, and price gaps – especially

Problems with EMH

If markets were efficient, prices would react in the same manner to all news, such as earnings or merger announcements.

Based on EMH, reaction to earnings surprises should be measured and precise, and not subject to correction.

EMH fails to recognize the elements of market behavior, which may be the most influential aspect of stock market investing and trading.

A view contrary to EMH

A contrarian has observed how irrationally price behaves, and how price tends to overreact to all unexpected news.

In these conditions, contrarians believe the market is quite inefficient.

If that is true, then exaggerated one‐day price movement presents an opportunity to exploit inefficiency.

Contrarians and the random walk theory

Page 14: Contrarian investing why works - Vanderbilt University · ‐traditional price reversal patterns like the head and shoulders, double tops or bottoms, and price gaps – especially

Definition

The random walk theory

Contrarians also reject the random walk theory, because the contrarian believes that price movement can be predicted –based on market behavior and on fundamental analysis.

If the random walk theory is true, then all forms of analysis are useless. The contrarian rejects the theory for that reason.

Random walk theory – a theory about the market stating that it is impossible to predict the direction of price movement, and that any price today has a 50% chance of rising or falling.

Page 15: Contrarian investing why works - Vanderbilt University · ‐traditional price reversal patterns like the head and shoulders, double tops or bottoms, and price gaps – especially

Problems with the random walk theory

If all prices were 50/50 bets, it would not matter which stock was selected; half would rise and half would fall.

Under the random walk, you must reject the effects of high revenue and earnings in one company, versus low results in an other.

You also would have to reject reputation, competitive success, and exceptional management. None of this would matter because price movement would occur apart from these influences.

Contrarians and the Dow Theory

Page 17: Contrarian investing why works - Vanderbilt University · ‐traditional price reversal patterns like the head and shoulders, double tops or bottoms, and price gaps – especially

Definition

The Dow Theory

Contrarians accept the basis of the Dow Theory over the long term, while also recognizing that short‐term price behavior tends to be chaotic and irrational.

The contrarian views the Dow Theory as an organizing principle of technical analysis, while also observing how volatile short‐term price movement and market behavior present trading opportunities.

Dow Theory – a series of “rules” about market trends and how they are set and reversed. The theory is based on the teachings of Charles Dow, one of the two founders of the Dow Jones Company.

The tenets of the Dow Theory

1. The market consists of three movements: primary, secondary and short‐term.

2. Trends consist of three phases: accumulation, public participation, and distribution.

3. The market tends to discount all news very quickly.

Page 19: Contrarian investing why works - Vanderbilt University · ‐traditional price reversal patterns like the head and shoulders, double tops or bottoms, and price gaps – especially

The tenets of the Dow Theory

4. Stock averages must confirm each other before a reversal is recognized.

5. Volume confirms trends.

6. Trends continue until a contrary signal is recognized and confirmed.

Is the Dow Theory in conflict with contrarian investing?

Many have pointed to the tenet that the market discounts news, to support the efficient market hypothesis.

It is true that the market behaves in this manner, but it often takes several days for the discounting to go into effect.

Contrarians are strong proponents of the Dow Theory over the long term, and recognize that the core of trend analysis rests with recognition of reversal and confirmation.

Conclusion

Contrarians do not act opposite the majority, but make decisions for different reasons than most – employing logic and analysis rather than emotion.

The efficient market hypothesis assumes that all prices are correct because they contain all known news.

The random walk theory assumes that prices cannot be predicted, and that all analysis is useless because of the random nature of markets.

The Dow Theory is the basis for technical analysis, and contrarians are strong proponents of its tenets.
