Before
beginning a study of the actual techniques and tools used in technical
analysis, it is necessary first to define what technical analysis is, to
discuss the philosophical premises on which it is based, to draw some clear
distinctions between technical and fundamental analysis and, finally, to
address a couple of criticisms frequently raised against the technical approach.
The
author's strong belief is that a full appreciation of the technical approach
must begin with a clear understanding of what technical analysis claims to be
able to do and, maybe even more importantly, the philosophy or rationale on
which it bases those claims.
First,
let's define the subject. Technical analysis is the study of market action,
primarily through the use of charts, for the purpose of forecasting future
price trends. The term "market
action" includes the three principal
sources of information available to the technician—price, volume, and open
interest. (Open interest is used only in futures and options.) The term "price action," which is often used, seems too
narrow because most technicians include volume and open interest as an integral
part of their market analysis. With this distinction made, the terms "price action" and "market action" are used interchangeably throughout
the remainder of this discussion.
There
are three premises on which the technical approach is based:
- Market
action discounts everything.
- Prices
move in trends.
- History
repeats itself.
- Market Action Discounts Everything
The
statement "market action
discounts everything" forms what is probably
the cornerstone of technical analysis. Unless the full significance of this
first premise is fully understood and accepted, nothing else that follows makes
much sense. The technician believes that anything that can possibly affect the
price—fundamentally, politically, psychologically, or otherwise—is actually
reflected in the price of that market. It follows, therefore, that a study of
price action is all that is required. While this claim may seem presumptuous,
it is hard to disagree with if one takes the time to consider its true meaning.
All
the technician is really claiming is that price action should reflect shifts in
supply and demand. If demand exceeds supply, prices should rise. If supply
exceeds demand, prices should fall. This action is the basis of all economic
and fundamental forecasting. The technician then turns this statement around
to arrive at the conclusion that if prices are rising, for whatever the
specific reasons, demand must exceed supply and the fundamentals must be
bullish. If prices fall, the fundamentals must be bearish. If this last
comment about fundamentals seems surprising in the context of a discussion of
technical analysis, it shouldn't. After all, the technician is indirectly
studying fundamentals. Most technicians would probably agree that it is the
underlying forces of supply and demand, the economic fundamentals of a market,
that cause bull and bear markets. The charts do not in themselves cause
markets to move up or down. They simply reflect the bullish or bearish
psychology of the marketplace.
As
a rule, chartists do not concern themselves with the reasons why prices rise
or fall. Very often, in the early stages of a price trend or at critical
turning points, no one seems to know exactly why a market is performing a
certain way. While the technical approach may sometimes seem overly simplistic
in its claims, the logic behind this first premise—that markets discount
everything—becomes more compelling the more market experience one gains. It
follows then that if everything that affects market price is ultimately
reflected in market price, then the study of that market price is all that is
necessary. By studying price charts and a host of supporting technical
indicators, the chartist in effect lets the market tell him or her which way it
is most likely to go. The chartist does not necessarily try to outsmart or
outguess the market. All of the technical tools discussed later on are simply
techniques used to aid the chartist in the process of studying market action.
The chartist knows there are reasons why markets go up or down. He or she just
doesn't believe that knowing what those reasons are is necessary in the
forecasting process.
Prices
Move in Trends
The
concept of trend is absolutely essential to the technical approach. Here again,
unless one accepts the premise that markets do in fact trend, there's no point
in reading any further. The whole purpose of charting the price action of a
market is to identify trends in early stages of their development for the
purpose of trading in the direction of those trends. In fact, most of the techniques
used in this approach are trend-following in nature, meaning that their intent
is to identify and follow existing trends. (See Figure 1.1.)
Figure
1.1 Example of an uptrend. Technical analysis is based on the premise that
markets trend and that those trends tend to persist.
There
is a corollary to the premise that prices move in trends—a trend in motion is
more likely to continue than to reverse. This corollary is, of course, an
adaptation of Newton's first law of motion. Another way to state this corollary
is that a trend in motion will continue in the same direction until it
reverses. This is another one of those technical claims that seems almost circular.
But the entire trend-following approach is predicated on riding an existing
trend until it shows signs of reversing.
History
Repeats Itself
Much
of the body of technical analysis and the study of market action has to do with
the study of human psychology. Chart patterns, for example, which have been
identified and categorized over the past one hundred years, reflect certain
pictures that appear on price charts. These pictures reveal the bullish or
bearish psychology of the market. Since these patterns have worked well in the
past, it is assumed that they will continue to work well in the future. They
are based on the study of human psychology, which tends not to change. Another
way of saying this last premise—that history repeats itself—is that the key to
understanding the future lies in a study of the past, or that the future is
just a repetition of the past.
While
technical analysis concentrates on the study of market action, fundamental analysis
focuses on the economic forces of supply and demand that cause prices to move
higher, lower, or stay the same. The fundamental approach examines all of the
relevant factors affecting the price of a market in order to determine the
intrinsic value of that market. The intrinsic value is what the fundamentals
indicate something is actually worth based on the law of supply and demand. If
this intrinsic value is under the current market price, then the market is
overpriced and should be sold. If market price is below the intrinsic value,
then the market is undervalued and should be bought.
Both
of these approaches to market forecasting attempt to solve the same problem,
that is, to determine the direction prices are likely to move. They just
approach the problem from different directions. The fundamentalist studies the
cause of market movement, while the technician studies the effect. The
technician, of course, believes that the effect is all that he or she wants or
needs to know and that the reasons, or the causes, are unnecessary. The fundamentalist
always has to know why.
Most
traders classify themselves as either technicians or fundamentalists. In
reality, there is a lot of overlap. Many fundamentalists have a working
knowledge of the basic tenets of chart analysis. At the same time, many
technicians have at least a passing awareness of the fundamentals. The problem
is that the charts and fundamentals are often in conflict with each other.
Usually at the beginning of important market moves, the fundamentals do not
explain or support what the market seems to be doing. It is at these critical
times in the trend that these two approaches seem to differ the most. Usually
they come back into sync at some point, but often too late for the trader to
act.
One
explanation for these seeming discrepancies is that market price tends to lead
the known fundamentals. Stated another way, market price acts as a leading
indicator of the fundamentals or the conventional wisdom of the moment. While
the known fundamentals have already been discounted and are already "in the market,"
prices are now reacting to the unknown fundamentals. Some of the most dramatic
bull and bear markets in history have begun with little or no perceived change
in the fundamentals. By the time those changes became known, the new trend was
well underway.
After
a while, the technician develops increased confidence in his or her ability to
read the charts. The technician learns to be comfortable in a situation where
market movement disagrees with the so-called conventional wisdom. A technician
begins to enjoy being in the minority. He or she knows that eventually the
reasons for market action will become common knowledge. It is just that the
technician isn't willing to wait for that added confirmation.
In
accepting the premises of technical analysis, one can see why technicians
believe their approach is superior to the fundamentalists. If a trader had to
choose only one of the two approaches to use, the choice would logically have
to be the technical. Because, by definition, the technical approach includes
the fundamental. If the fundamentals are reflected in market price, then the
study of those fundamentals becomes unnecessary. Chart reading becomes a
shortcut form of fundamental analysis. The reverse, however, is not true.
Fundamental analysis does not include a study of price action. It is possible
to trade financial markets using just the technical approach. It is doubtful
that anyone could trade off the fundamentals alone with no consideration of
the technical side of the market.
This
last point is made clearer if the decision making process is broken down into
two separate stages—analysis and timing.
Because
of the high leverage factor in the futures markets, timing is especially
crucial in that arena. It is quite possible to be correct on the general trend
of the market and still lose money. Because margin requirements are so low in
futures trading (usually less than 10%), a relatively small price move in the
wrong direction can force the trader out of the market with the resulting loss
of all or most of that margin. In stock market trading, by contrast, a trader
who finds him or herself on the wrong side of the market can simply decide to
hold onto the stock, hoping that it will stage a comeback at some point.
Futures
traders don't have that luxury. A "buy and hold" strategy doesn't
apply to the futures arena. Both the technical and the fundamental approach can
be used in the first phase—the forecasting process. However, the question of
timing, of determining specific entry and exit points, is almost purely
technical. Therefore, considering the steps the trader must go through before
making a market commitment, it can be seen that the correct application of
technical principles becomes indispensable at some point in the process, even
if fundamental analysis was applied in the earlier stages of the decision.
Timing is also important in individual stock selection and in the buying and
selling of stock market sector and industry groups.
