A
CAPSULE SUMMARY OF THE WAVE PRINCIPLE
The Wave Principle is Ralph Nelson Elliott's
discovery that social, or crowd, behavior trends
and reverses in recognizable patterns. Using
stock market data as his main research tool,
Elliott isolated thirteen patterns of movement,
or "waves," that recur in market price
data. He named, defined and illustrated those
patterns. He then described how these structures
link together to form larger versions of those
same patterns, how those in turn link to form
identical patterns of the next larger size, and
so on. In a nutshell, then, the Wave Principle is
a catalog of price patterns and an explanation of
where these forms are likely to occur in the
overall path of market development.
Pattern Analysis
Until a few years ago, the idea that market
movements are patterned was highly controversial,
but recent scientific discoveries have
established that pattern formation is a
fundamental characteristic of complex systems,
which include financial markets. Some such
systems undergo "punctuated growth,"
that is, periods of growth alternating with
phases of non-growth or decline, building
fractally into similar patterns of increasing
size. This is precisely the type of pattern
identified in market movements by R.N. Elliott
some sixty years ago.
The basic pattern Elliott described consists
of impulsive waves (denoted by numbers)
and corrective waves (denoted by letters).
An impulsive wave is composed of five subwaves
and moves in the same direction as the trend of
the next larger size. A corrective wave is
composed of three subwaves and moves against
the trend of the next larger size. As Figure 1
shows, these basic patterns link to form
five- and three-wave structures of increasingly
larger size (larger "degree" in Elliott
terminology).
In Figure 1, the first small sequence is an
impulsive wave ending at the peak labeled 1. This
pattern signals that the movement of one larger
degree is also upward. It also signals the start
of a three-wave corrective sequence, labeled wave
2.

Figure 1
Waves 3, 4 and 5 complete a larger impulsive
sequence, labeled wave (1). Exactly as with wave
1, the impulsive structure of wave (1) tells us
that the movement at the next larger
degree is upward and signals the start of a
three-wave corrective downtrend of the same
degree as wave (1). This correction, wave (2), is
followed by waves (3), (4) and (5) to complete an
impulsive sequence of the next larger degree,
labeled wave [1]. Once again, a three-wave
correction of the same degree occurs, labeled
wave [2]. Note that at each "wave one"
peak, the implications are the same regardless of
the size of the wave. Waves come in degrees, the
smaller being the building blocks of the larger.
Here are the accepted notations for labeling
Elliott Wave patterns at every degree of trend:

*degrees normally denoted by
circles are here presented with brackets.
Within a corrective wave, waves A and C may be
smaller-degree impulsive waves, consisting of
five subwaves. This is because they move in the
same direction as the next larger trend, i.e.,
waves (2) and (4) in the illustration. Wave B,
however, is always a corrective wave, consisting
of three subwaves, because it moves against
the larger downtrend.
Within impulsive waves, one of the
odd-numbered waves (usually wave three) is
typically longer than the other two. Most
impulsive waves unfold between parallel lines
except for fifth waves, which occasionally unfold
between converging lines in a form called a
"diagonal triangle." Variations in
corrective patterns involve repetitions of the
three-wave theme, creating more complex
structures that are named with such terms as
"zigzag," "flat,"
"triangle" and "double
three." Waves two and four typically
"alter-nate" in that they take
different forms.
Each type of market pattern has a name and a
geometry that is specific and exclusive under
certain rules and guidelines, yet variable enough
in other aspects to allow for a limited diversity
within patterns of the same type. If indeed
markets are patterned, and if those patterns have
a recognizable geometry, then regardless of the
variations allowed, certain relationships in
extent and duration are likely to recur. In fact,
real world experience shows that they do. The
most common and therefore reliable wave
relationships are discussed in Elliott Wave
Principle, by A.J. Frost and Robert Prechter.
Applying the Wave Principle
The practical goal of any analytical method is
to identify market lows suitable for buying (or
covering shorts), and market highs suitable for
selling (or selling short). The Elliott Wave
Principle is especially well suited to these
functions. Nevertheless, the Wave Principle does
not provide certainty about any one market
outcome; rather, it provides an objective means
of assessing the relative probabilities of
possible future paths for the market. At any
time, two or more valid wave interpretations are
usually acceptable by the rules of the
Wave Principle. The rules are highly specific and
keep the number of valid alternatives to a
minimum. Among the valid alternatives, the
analyst will generally regard as preferred the
interpretation that satisfies the largest number
of guidelines and will accord top
alternate status to the interpretation satisfying
the next largest number of guidelines, and so on.
Alternate interpretations are extremely
important. They are not "bad" or
rejected wave interpretations. Rather, they are
valid interpretations that are accorded a lower
probability than the preferred count. They are an
essential aspect of investing with the Wave
Principle, because in the event that the market
fails to follow the preferred scenario, the top
alternate count becomes the investor's backup
plan.
Fibonacci Relationships
One of Elliott's most significant discoveries
is that because markets unfold in sequences of
five and three waves, the number of waves that
exist in the stock market's patterns reflects the
Fibonacci sequence of numbers (1, 1, 2, 3, 5, 8,
13, 21, 34, etc.), an additive sequence that
nature employs in many processes of growth and
decay, expansion and contraction, progress and
regress. Because this sequence is governed by the
ratio, it appears throughout the price and time
structure of the stock market, apparently
governing its progress.
What the Wave Principle says, then, is that
mankind's progress (of which the stock market is
a popularly determined valuation) does not occur
in a straight line, does not occur randomly, and
does not occur cyclically. Rather, progress takes
place in a "three steps forward, two steps
back" fashion, a form that nature prefers.
As a corollary, the Wave Principle reveals that
periods of setback in fact are a requisite for
social (and perhaps even individual) progress.
Implications
A long term forecast for the stock market
provides insight into the potential changes in
social psychology and even the occurrence of
resulting events. Since the Wave Principle
reflects social mood change, it has not been
surprising to discover, with preliminary data,
that the trends of popular culture that also
reflect mood change move in concert with the ebb
and flow of aggregate stock prices. Popular
tastes in entertainment, self-expression and
political representation all reflect changing
social moods and appear to be in harmony with the
trends revealed more precisely by stock market
data. At one-sided extremes of mood expression,
changes in cultural trends can be anticipated.
On a philosophical level, the Wave Principle
suggests that the nature of mankind has within it
the seeds of social change. As an example simply
stated, prosperity ultimately breeds reactionism,
while adversity eventually breeds a desire to
achieve and succeed. The social mood is always in
flux at all degrees of trend, moving toward one
of two polar opposites in every conceivable area,
from a preference for heroic symbols to a
preference for anti-heroes, from joy and love of
life to cynicism, from a desire to build and
produce to a desire to destroy. Most important to
individuals, portfolio managers and investment
corporations is that the Wave Principle indicates
in advance the relative magnitude of the
next period of social prog-ress or regress.
Living in harmony with those trends can make
the difference between success and failure in
financial affairs. As the Easterners say,
"Follow the Way." As the Westerners
say, "Don't fight the tape." In order
to heed these nuggets of advice, however, it is
necessary to know what is the Way, and which way
the tape. There is no better method for answering
that question than the Wave Principle.
