Before
we adapt the KST to the market cycle model, it’s a good idea to take a look at
the type of trend(s) you are monitoring.
Technical analysts recognize the fact that there are many different
trends interacting simultaneously. The
three most common trends are represented in Figure 1. They are the primary, intermediate, and short-term trends.

Figure 1
The
primary trend generally lasts between 1 to 2 years, and is the reflection of investors'
attitudes toward unfolding fundamentals in the business cycle. The business cycle statistically lasts from
beginning to end for approximately 3 to 6 years. As a result, the rising and falling primary trends (bull and bear
markets) within a complete cycle last, on average, for 1 to 2 years, although
it is possible to experience trends that are much longer. The 1- to 2-year timeframe should only be
used as a rough guide so that most primary trends are included. And since building up takes longer than
tearing down, bull markets generally last longer than bear markets.
The
primary trend is illustrated in Figure 1 by the thick green line. In a perfect world, the primary uptrend
(bull market) would be the same size as the primary downtrend (bear market). In reality though, their magnitudes are
different, and so are their timeframes.
The
primary trend cycle can be applied to bonds, equities, and commodities. The cycle can work with currencies, but
because currencies reflect investors' attitudes toward the interrelationship of
two different economies, they don’t fit neatly into the business cycle
approach, making analysis difficult.
A
primary uptrend is interrupted by a series of reactions along the way. These counter-cyclical trends that occur
within the confines of a primary bull market are known as intermediate price
movements, or the intermediate trend. The
intermediate trend lasts anywhere from 6 weeks to as long as 9 months,
sometimes even longer, but rarely shorter.
Intermediate trend analysis is a useful tool in determining
when the primary trend has run its course, therefore improving your trading
success rate.
Intermediate
trends typically develop with the emergence of some kind of economic, monetary,
or psychological factor, and create uncertainty in market participants about
the prevailing primary trend is still being in force.
Short-term
trends typically last 3 to 4 weeks, but like the other trends, can vary in
magnitude. Shown in Figure 1 as a red
dashed line, they interrupt the course of the intermediate cycle, just as the
intermediate-term trend interrupts primary price movements. Short-term trends are usually influenced by
random news events, so are far more difficult to identify than their
intermediate, or primary counterparts.
Since
long-term investors are mainly concerned with the direction of the primary
trend, it is important for them to identify the maturity of the prevailing
bull, or bear market. However, long-term
investors must also be aware of intermediate- and, to a lesser extent,
short-term trends because an important step in market cycle analysis is
the understanding of the relationship between short- and intermediate-term
trends and how they affect the primary trend.
Here’s a
good example: If you decide the long-term trend has just reversed to the
upside, it could pay to wait before committing capital because the short-term
trend is overextended on the upside.
The eventual short-term correction offers you a timelier, and more
profitable entry point. Were you not
aware of the short-term trends’ position, it could have proven very costly at
the margin.
Finally,
trading losses often develop because the trader is positioned in a counter
cyclical (against the primary trend) position, where whipsaw breakouts
typically occur. That's why short-term upside breakouts are far more likely to
fail in a primary bear market than a primary bull market and vice versa. For this reason it’s imperative that all
market participants have a working knowledge of these three trends. The amount and emphasis of knowledge will
depend on their perspective, longer-term investment, or short-term trader.
The best
entry point for trading/investing occurs when the primary trend is rising and
both the intermediate- and short-term trends are bottoming out. The opposite occur during a primary bear
market, where the best exit/selling opportunities occur when the intermediate-
and short-term trends are peaking. This
is because oscillators are far more sensitive to oversold conditions in a bull
market and vice versa.
It’s also
important to know the state of maturity of the primary trend because a
trade/investment made during the early to middle stages of a bull market are
supported by the rising primary trend.
This is not the case when you enter close to the end of the trend, and
certainly is not the case during the ensuing bear market.

Chart 1
It would be the ideal situation to track the KST for monthly, weekly, and daily data on the same chart, but plotting constraints don’t always permit this. However, you can simulate these three trends by using different time spans based on weekly data, shown for the Euro in Chart 1. This arrangement allows you to identify both the direction and the maturity of the primary trend (shown at the bottom), as well as the interrelationship between the short- and the intermediate trends. The green and red highlights indicate those periods when the long-term KST is above and below its 26-week EMA, respectively. Notice that the short-term KST rarely moves to the oversold zone during the bullish environments and rarely to the overbought when the main trend is down. Also how the short-term KST trades in a lower band during bear markets and a higher one when primary trend conditions, as flagged by the long-term KST, are positive.
You can
find vital clues from the action of the short- and intermediate series in
conjunction with the price action. For
example, in late 2000, the long-term KST was still declining, but the high
reading in the short-term series was more indicative of a bull, rather than a
bear market characteristic. This was a
subtle tip-off that a new bull market was underway. The short, and intermediate KSTs had also previously violated
down trendlines, and the currency itself experienced a similar phenomenon. This trend break was not enough to signal a
trend reversal, but its violation suggested that downside momentum would
dissipate enough to allow the long-term KST to reverse direction.

The KST
adapts well to relative strength relationships, and is especially useful when
the long-term KST is applied to industry groups or individual stocks. This is because linear up- and down trends
are far less likely to develop during the rotational process around the
business cycle than with absolute price data.
For
example, Chart 2 shows the NASDAQ/S&P Ratio. The green highlights flag those periods when the long- and
intermediate-term KSTs are above their EMAs and the price itself is above its
10-week EMA. Please note that the
average shown in the chart is a 26-week not a 10-week EMA. Red highlights develop under the exact
opposite set of conditions. While there
are a few whipsaws, it’s evident that this pro trend system captures a substantial
part of the big up and down moves.
