Technical
Analysis and Trend Identification
Technical analysis involves a study of the action of markets, it is not
concerned with the difficult and subjective tasks of forecasting
trends in the economy, or assessing the attitudes of investors
toward those changes. Technical analysis tries to identify turning
points in the market's assessment of these factors.
Since
technical analysis can be applied successfully to
any freely traded entity such as stocks, market
averages, commodities, bonds, currencies, and so on,
I will frequently use the term security as a generic
one embracing all of these entities, thereby
avoiding unnecessary repetition.
Price
patterns, trend-lines, moving averages (MAs),
momentum, and so on are "Trend-Determining
Techniques," techniques used to determine trends and
identify their reversals.
A
study of market character is a cornerstone of
technical analysis, since reversals of price trends
in the major averages are almost always preceded by
latent strength or weakness in the market structure.
Technical analysis looks further than the price
trends of the popular averages. Trends of investor
confidence are responsible for price movements, and
this emotional aspect is examined from four
viewpoints or dimensions, namely, price, time,
volume, and breadth.
Changes
in prices reflect changes in investor attitude.
Price, the first dimension, indicates the level of
that change. Time,
the second
dimension, measures the recurrence and length of
cycles in investor psychology. Changes in confidence
go through distinct cycles, some long and some
short, as investors swing from excesses of optimism
toward deep pessimism. The degree of price movement
in the market is usually a function of the time
element. The longer it takes for investors to move
from a bullish to a bearish extreme, the greater the
ensuing price change is likely to be.
Volume,
the third
dimension, reflects the intensity of changes in
investor attitudes. For example, the level of
enthusiasm implied by a price rise on low volume is
not nearly as strong as that implied by a similar
price advance accompanied by very high volume.
The
fourth dimension, breadth, measures the extent of
the emotion. This is important because as long as
stocks are advancing on a broad front, the trend in
favorable emotion is dispersed among most stocks and
industries, indicating a healthy and broad economic
recovery and a widely favorable attitude toward
stocks in particular. On the other hand, when
interest has narrowed to a few blue-chip stocks, the
quality of the trend has deteriorated, and a
continuation of the bull market is highly suspect.
Technical
analysis measures these psychological dimensions in
a number of ways. Most indicators monitor two or
more aspects simultaneously; for instance, a simple
price chart measures both price (on the vertical
axis) and time (on the horizontal axis). Similarly,
an advance/decline line measures breadth and time.
