Abstract: - Previous studies of momentum strategies and contrarian strategies have focused on debating the
advantages of each strategy separately without attempting integration. The aim of this study was to test the
effects of combining these two strategies into a dynamic approach, using Ichimoku as a mediator. This
quantitative research uses daily stock prices taken from the Indonesia Stock Exchange website to analyze the
mechanism of the relationship between heuristics and investment performance. Our research demonstrates the
superior performance of the Dynamic strategy in generating higher returns when compared to alternative
strategies. One of the main reasons behind this success is how well Ichimoku can navigate this indirect
influence. The proposed model demonstrates strong predictive abilities and sets itself apart from the strategies
that influence its development. Investors of all backgrounds, including individuals, can easily integrate this
innovative strategy. Therefore, the study makes a valuable contribution to improving investment strategies,
making them more comprehensive and effective.

1 Introduction
Investment judgments often rely on anchor and
representative heuristics, particularly when technical
analysis lacks robust information support. These
heuristics assist in simplifying intricate situations
and rapidly assessing the likelihood of events under
time limitations, [1]. The anchor and adjustment
heuristics involve using initial reference values and
modifying them based on further information [2],
[3], [4]. These heuristics help simplify complex
situations and quickly assess event probabilities
when time is limited. The anchor and adjustment
heuristics involve making adjustments to initial
reference values based on new information. In
contrast, "representativeness heuristics" involves
assessing how closely an event matches a particular
category. Investors often anticipate success with
high-performing stocks and frequently rely on
representativeness heuristics to develop trading
strategies, [5]. Understanding heuristics in
investment decision-making is crucial for both
investors and policymakers because it elucidates
how individuals navigate uncertainty in financial
markets.
One commonly used rule of thumb in investment
decision-making is to consider the highest (lowest)
price within the last 52 weeks, [6]. This data is easy
to find through various commonly used trading
platforms, such as TradingView.com,
Investing.com, and even the official website of the
Indonesia Stock Exchange.
Using heuristics in investment decision-making
may deviate from the efficient market hypothesis;
therefore, investors must understand how to employ
them [7], [8]. For instance, when contemplating the
use of the representativeness heuristic, several
traders rely on the presumption that equities priced
at a 52-week high (or low) are either overvalued or
undervalued. This impression frequently leads
traders to fail to respond to the available
information. However, as this information proves

accurate over time, traders will adjust their methods.
This adjustment encourages a sustainable trend-
direction pattern, [9].
The use of heuristics creates bias. Some previous
researchers have obtained evidence regarding the
reliability of momentum strategies, namely
strategies that buy shares that perform well and sell
shares that perform poorly, in generating excess
returns, [10], [11], [12], [13], [14]. Conversely,
some traders view stocks that are near 52-week
highs (lows) as indicators of stocks with over- (or
under-) performance. This view, however, often
results in an overreaction. When this perception
proves misguided, traders readjust their opinions,
which contributes to long-term price reversals, [15],
[16]. Empirical evidence also suggests that
contrarian strategies, such as buying
underperforming stocks and selling well-performing
stocks, can offer superior returns, [17], [18], [19],
[20], [21], [22]. This observation highlights a
significant gap in the field's knowledge and
underscores the importance of understanding how
traders employ heuristics to craft more precise
investment strategies when making investment
decisions. To maximize returns for investors, such
schemes must carefully consider behavioral biases
and market dynamics.
This observation highlights a gap in current
research, emphasizing the importance of
understanding how traders use heuristics to develop
more appropriate and effective investment
strategies. To maximize investor returns, it is
important for strategies to take behavioral biases
and market dynamics seriously.
Additionally, previous research often advocates
one approach over another without considering that
integration is often the best approach. However,
these obstacles have hampered our ability to study
how market dynamics interact with investment
outcomes. One distinct limitation is that, with a few
exceptions distinct limitation is that, with a few
exceptions, [23]. The literature does not offer
detailed causal mechanisms to explain how
heuristics can impact investment performance.
Ignoring these gaps will prevent us from fully
understanding how they affect our bottom line
(costs).
The aim of this study is to bridge that gap
process-wise by dissecting momentum and
contrarian strategies in a dynamically integrated
manner, with Ichimoku as the mediator. Despite its
prognostic capabilities, Ichimoku remains relatively
unexplored. By adopting an integrative
methodology, this research paper presents a new
viewpoint that highlights the benefits of dynamic
strategies compared to other evaluated approaches.
This research aims to explain the complex
interrelationships among various investment
strategies and evaluate the predictive validity of the
model we have developed. Furthermore, our
research seeks to establish significant distinctions
between dynamic strategies and other
methodologies that have undergone testing.
This study's novelty lies in its attempt to fill a
gap in understanding the basic mechanisms linking
heuristics to investment performance. We
underscore the potential of this research to bridge
existing gaps in the literature and enhance our
comprehension of the intricacies of financial
markets and investment dynamics, encompassing
phenomena like disposition effects. This study
provides a new perspective on investment strategies
and improves investors' ability to make informed
decisions, thereby potentially improving overall
investment performance.
The following sections of the study will explore
the proposed model outlined in Part 2, outline the
data and methodology described in Part 3, present
the results obtained in Part 4, discuss the findings in
Part 5, and finally conclude with comprehensive
conclusions in the last section.
2 Propose Model
To answer the research question, we propose a
model as depicted in Figure 1. This model visually
illustrates the direct and indirect influence of
Momentum and Contrarian strategies on Dynamic
strategies, mediated by Ichimoku. Based on initial
predictions, the overall Dynamic strategy shows
statistically significant differences compared to the
Momentum, Contrarian, and Ichimoku strategies.
The H1 to H7 hypotheses detail the expected
influence of various strategies on Dynamic
strategies. These influences include both direct and
indirect impacts. Direct impact refers to the direct
influence of each strategy on the Dynamic strategy.
Hypotheses 1, 2, and 3 propose the positive impact
of Momentum, Contrarian, and Ichimoku strategies
on Dynamic Strategies, while Hypotheses 4 and 5
note the positive impact of Momentum and
Contrarian strategies on Ichimoku strategies.
In addition, we also pay attention to the indirect
influence of each strategy on Dynamic strategies
through Ichimoku. Hypotheses 6 and 7 hypothesize
that Momentum and Contrarian strategies influence
Dynamic strategies after mediation by Ichimoku.

3 Data and Methodology
3.1 Samples and Procedures
This research uses a quantitative approach to
analyzing stock price movements in the Indonesian
market. The secondary data used is the daily stock
price taken from the Indonesia Stock Exchange
website, which is [24]. This data set was
strategically selected to cover the time span from
January 3, 2017, to September 29, 2023, so as to
capture various market conditions, including when
the market is in a bullish and bearish trend. A
comprehensive accounting of 88 actively traded
equities has been recognized. We have compiled
complete data on these equities, taking into account
dividends and stock splits. The return calculation
will begin on January 2, 2018. This comprehensive
data set provides a solid foundation for careful study
and in-depth observation of various market
conditions.
3.2 Winner and Loser
We used a two-step heuristic process rooted in holds
to distinguish the good picks from the bad ones in
our stock-picking methodology. Here, the method
rests on two key points of reference: price highs and
lows that occurred in the past 52 weeks [6]. We
calculate the winners and losers through the Nearest
Ratio (NR), a comparison of the close price with the
52-week low within the range of its highest and
lowest prices in the same period. This formula for
the closeness ratio is one of the key parts of our data
analysis.
Winning stocks are those stocks that are nearest
their all-time high and losing stocks are those
closest to their all-time low in finance. Using the
Nearest Ratio (NR) that compares the closing price
to the 52 weeks, we classify winners and losers:


(1)
Where NR is nearest ratio in this equation the 52
weeks high or low where  is the previous
day's closing price. Beside that  and
 mean the 52-week high/low prices of the
stock the fortnight ending yesterday, t−1. The
calculation of NR will result in a value that ranges
from 0 to 1. A higher value indicates that the price
has approached the highest price in the last 52
weeks and vice versa.
The determination of Winner and Loser shares is
based on the magnitude of NR value with a
threshold of 30% [6], [25]. The selection of these
thresholds is to ensure a degree of precision,
empirical support, consistency with heuristic
practices, noise reduction, and wide applicability
across a wide range of market conditions. This
method can increase the durability and practicality
of the chosen trading strategy. Winners are
identified as stocks with an NR value exceeding
70%, while losers are stocks with an NR value of
less than 30%.
3.3 Ichimoku
The method was started in the late 1930s and
expanded even more in the 1960s. When translated
from Japanese, the term "Ichimoku Kinko Hyo"
means "one glance equilibrium chart", [26].
Ichimoku reflects in its very name what it does best:
it offers a "glance" at a chart and directly shows the
equalized price movement in its entirety.
Ichimoku, a multifaceted and user-friendly
analytical tool, may be utilized across many
investing time frames and asset categories. Traders
and analysts find Ichimoku to be an indispensable
resource due to its remarkable adaptability in
identifying trends, evaluating market momentum,
and determining support and resistance levels.
Ichimoku is a trading tool utilized by traders to
evaluate market momentum, identify trends, and
ascertain potential support and resistance levels.
"The historical development of the Ichimoku Kinko
Hyo concept, from its origins to its modern-day
applications, underscores its enduring significance
in technical analysis. This underscores the
reliability, flexibility, and value of Ichimoku in
guiding traders through ever-changing market
conditions, underscoring its importance in adapting
to shifting trends. By applying the Ichimoku
indicator, traders can develop a deeper
understanding of market dynamics. This allows
them to make decisions based on a thorough

analysis of trends and support/resistance levels.
Better understanding and intelligent decision-
making abilities have the potential to lead to greater
profits and success in the financial markets.
The mathematical expressions utilized to
compute Ichimoku elements bear conceptual
resemblances to conventional moving averages. The
method employs a mid-point moving average. The
Tenkan-sen (TK) represents short-term moving
averages, whereas the Kijun-sen (KJ) represents
medium-term moving averages. Senkou-span A
(SKA) and Senkou-span B (SKB) might be likened
to long-term moving averages. The uniqueness lies
in the use of the median of the highest and lowest
prices over a certain period in Ichimoku. Chikou-
span (CK) serves as a momentum indicator,
providing insights into possible trends.
The standard period parameters in Ichimoku are
9, 26, and 52. This systematic approach contributes
to Ichimoku's efficacy as a technical analysis tool
that is robust and adaptable, [27], [28].

In representing the formulation, where
󰇛󰇜 and 󰇛󰇜represent the highest and
lowest prices during the T period, and denotes
the closing prices, the Ichimoku strategy is
constructed. The crossover between Tenkan and
Kijun is a pivotal indicator of the trend direction. A
Tenkan-sen crossover from the bottom to the top of
the Kijun-sen signals the emergence of a bullish
trend, whereas a crossover from the top to the
bottom indicates a bearish trend.
The price position relative to the Kumo, or cloud,
provides insights into the trend's strength. In a
bullish trend, a bottom-to-top breakout (penetration)
of the cloud signifies a robust trend. Conversely, in
a bearish trend, a top-to-bottom penetration of the
cloud indicates a strong bearish trend. The Chikou-
span is employed to confirm trend formation.
3.4 Trading Strategy
Guided by the NR formula, the Momentum strategy
() involves purchasing shares with an NR
value exceeding 70% and selling shares with an NR
value falling below 30%, thus aligning with the
established criteria for winners and losers.

(7)
On the contrary, the contrarian strategy ()
entails purchasing shares with an NR value of less
than 30% and selling shares with an NR value
exceeding 70%. Concurrently, shares with an NR
value falling within 30% to 70% adhere to the
established trading signals from preceding periods.

The Ichimoku strategy amalgamates these five
elements to generate buy or sell signals. Three key
Ichimoku () rules, encompassing the crossover
between Tenkan and Kijun, Tenkan-sen crossover,
price position against Kumo, and confirmation by
Chikou-span, are integrated to formulate these
signals.

3.6 Methodologies
This study presents a new dynamic trading strategy
that integrates momentum and contrarian strategies
using Ichimoku as a mediator. For this reason, we
tested whether there are differences between these
trading strategies. Additionally, we analyzed the
effects of momentum and contrarian trading
strategies on dynamic strategies, considering both
direct and indirect impacts. Direct impact relates to
the direct influence of each strategy on the dynamic
strategy, while indirect impact includes the
influence of each strategy on the dynamic strategy
through Ichimoku.
3.7 Confirmatory Composite Analysis
(CCA)
Confirmatory composite analysis (CCA) was used
to assess the quality of measurement models in PLS-
SEM, [30], [31]. This approach, an alternative to
confirmation factor analysis (CFA), is used to
confirm measurement models when using partial
least squares structural equation (PLS-SEM)
modeling. The evaluation process encompasses
three primary steps; however, since the study
exclusively employs formative measurements, the
evaluation comprises: (1) scrutinizing the formative
measurement model by analyzing redundancy,
variance inflation factor (VIF), and the significance
and relevance of indicator weights. (2) Assessing
the structural model through VIF examination,
alongside scrutinizing the significance and
relevance of path coefficients, explanatory and
predictive power, and evaluating the goodness of fit
through relevant measures. Given the non-linear
dynamics inherent in stock price movements,
WarpPLS 8 utilizes a sophisticated non-linear
algorithm to navigate these complexities. Given the
non-linear nature of stock price movements,
WarpPLS 8 uses a non-linear algorithm.
3.8 Kruskal-Wallis test
The Kruskal-Wallis test, a non-parametric analysis
tool, was pivotal in evaluating differences among
the integrated trading strategies. This method
proved well-suited for assessing excess returns,
particularly in financial contexts where normality
and equal variance assumptions may not hold. By
focusing on medians, it provided insights into
performance variations across Momentum,
Contrarian, Ichimoku, and Dynamic strategies.
Subsequently, a post hoc analysis using Dunn's Test
delved deeper into the nuances of the results,
identifying specific pairs of strategies exhibiting
statistically significant differences. This robust
statistical approach, with a predetermined threshold
of 0.05, enhanced the credibility of our findings,
contributing to a nuanced understanding of
comparative effectiveness. Additionally, a separate
test using SPSS 25 software ensured the
distinctiveness of the dynamic strategy from
momentum and contrarian strategies.
4 Results
4.1 Descriptive Statistics
The data analysis in Table 1 reveals distinct
characteristics for each strategy. The Momentum
Strategy (MOM) demonstrates a growth trend, with
a positive mean of 0.259, indicating potential for
positive returns. Conversely, the Contrarian Strategy
(CON) embodies a contrarian trend, with an
opposing average of -0.265, suggesting potential
losses. Notably, the Ichimoku Strategy (ICH) stands
out with a relatively high average of 1,653,
showcasing robust performance. However, the
Dynamic Strategy (DYN) is the most noteworthy,
boasting the highest average of 2,733, denoting
substantial profit potential. With a remarkable
maximum value of 10,717, the Dynamic Strategy
emerges as the superior choice during this research
period, albeit with heightened volatility compared to
other strategies. Consequently, the data substantiate
the conclusion that the Dynamic Strategy exhibits
superior yield potential compared to Momentum,
Contrarian, and Ichimoku in this observational
period.
The histograms in Figure A1 (Appendix) provide
a visual representation of how excess returns are
distributed across various investment strategies. In
the Momentum Strategy, the majority of returns lie
between -100% and 300%, with a positive skewness
(0.890), suggesting a tendency towards higher
positive returns. Conversely, the Contrarian Strategy

shows returns primarily within the range of -300%
to 100%, exhibiting a negative skewness (-1.628),
indicating a prevalence of lower negative returns.
For the Ichimoku Strategy, returns are clustered
between 0% and 600%, with a positive skewness
(1.366), indicating a preference for higher positive
returns. Meanwhile, the Dynamic Strategy displays
a wider range of returns, centered around 200% to
800%, and the highest positive skewness (1.647),
highlighting a strong inclination towards higher
positive returns. These insights enable investors to
assess the risk and return characteristics of each
strategy, with the Dynamic Strategy particularly
noteworthy for its potential for higher returns
despite increased volatility.

4.2 Evaluation Criteria (Formative Models)
Convergent validity, collinearity, and the
importance and applicability of indicator weights
were the three main areas of emphasis for this in-
depth analysis of the formative models. The study
employed redundancy analysis to evaluate
convergent validity. The analysis found loading
factors with values of 1 and P-values less than
0.001, indicating that the convergent validity was
satisfactory, [32]. The collinearity test carried out
using the Variance Inflation Factor (VIF) produced
values ranging from 1.090 to 1.284. These results
indicate that there are no vertical multicollinearity
problems in the data. In addition, this study
confirmed the significance and relevance of the
indicator weights, as all P values were below 0.05.
The results of our analysis confirm the
dependability and strength of the formative
constructs used in our study.
4.3 Evaluation of Structural Models
Evaluation of structural models encompasses
several key aspects: Collinearity, Significance, and
relevance of path coefficients, Explanatory power,
and Predictive power, [30], [31].
4.3.1 Collinearity
In the process of evaluating the structural model, the
first crucial step is to assess multicollinearity to
ensure the reliability of regression results. This is
typically achieved through a comprehensive VIF
multicollinearity test. Based on the VIF values
reported in Table 2, the variables MOM and CON
have relatively low VIF values of 1.184 and 1.099,
respectively, indicating minimal multicollinearity.
However, the ICH and DYN variables have higher
VIF values of 4.758 and 4.512 respectively,
indicating potential multicollinearity between
variables, but they are still acceptable because they
are below the threshold of 5, [30].
Taking care of multicollinearity worries now is
crucial. It helps make sure our analyses down the
line are solid and precise. When we're sure
multicollinearity isn't an issue, we can trust our
interpretations of the path coefficients more
confidently. Plus, it means we're doing a better job
of evaluating how well our model explains and
predicts things, which is what we're aiming for [30].
It is crucial to acknowledge and resolve concerns
pertaining to multicollinearity during this phase, as
doing so enhances the reliability and precision of
subsequent analyses. By verifying the lack of
substantial multicollinearity, we can proceed with
increased certainty in interpreting the importance
and relevance of path coefficients. Furthermore, this
practice guarantees a more comprehensive
evaluation of the explanatory and predictive strength
of the structural model, which is consistent with our
research aims.

4.3.2 Path Coefficient Analysis
Table 3 details the significant findings from the path
coefficient analysis regarding the interrelationships
among different trading strategies. The first results
show that the negative path coefficients for MOM
DYN and CON DYN are not statistically significant
(-0.084 and -0.068, respectively), as shown by the p-
values that are higher than the 0.05 significance
level. There is no substantial direct correlation
between the momentum strategy (MOM) or
contrarian strategy (CON) and the dynamic strategy
(DYN). The inference is that the use of MOM or
CON does not have a direct impact on the dynamic
strategy's efficacy, as previously postulated.

On the other hand, a highly significant positive
path coefficient for ICH → DYN (0.821) indicates a
strong and positive relationship between the
Ichimoku variable (ICH) and dynamic strategy
(DYN). Additionally, a significant positive path
coefficient for MOM ICH (0.407) and a
significant negative path coefficient for CON
ICH (-0.196) indicate that MOM and CON
significantly influence the use of Ichimoku in the
context of stock trading.

In addition, the findings indicated that the
indirect impacts of MOM and CON on DYN
through ICH (0.271 and 0.457, respectively) were
also statistically significant. These results provide
support for the hypothesis that Ichimoku facilitates
the integration of MOM and CON, thereby
significantly augmenting the performance of
dynamic strategies.
This underscores Ichimoku's mediating role in
the relationship between MOM/CON and DYN.
Although some hypotheses were not supported, the
results of this study show that Ichimoku has a
significant influence as a mediator between
momentum, contrarian, and dynamic strategies in
the trading context.
4.3.3 Explanatory Power
Next, the Explanatory Power test was conducted
using the R-square value to assess the extent to
which independent variables can explain the
variation in the dependent variable. In the context of
this study, an R-square value of 0.250 for ICH
indicates that MOM and CON still have relatively
low explanatory power. It is important to note that
R-square values of 0.75, 0.50, and 0.25 are
considered substantial, moderate, and weak
predictors, respectively [30]. The contributions of
MOM and CON to the R-square value, at 0.189 and
0.061 for MOM ICH and CON ICH
respectively, suggest a moderate and weak
contribution of both variables to the variation in
ICH. As a guide, f-square values of 0.02, 0.15, and
0.35 respectively represent small, medium, and
large effects of an exogenous latent variable, [32].
However, collectively they offer a moderately
explanatory power for DYN, as indicated by an R-
square value of 0.705. Furthermore, the fact that the
R-square value remains below 0.90 indicates that
the model does not suffer from overfitting [30]. The
contributions of MOM, CON, and ICH to the R-
square value of DYN (-0.038, 0.023, and 0.720
respectively) suggest a moderate impact for MOM
and CON, and a substantial impact for ICH. It is
noteworthy that MOM's contribution is opposite to
the direction of DYN. These findings suggest that
MOM and CON have a greater impact when
mediated by ICH compared to when they directly
influence DYN.
4.3.4 Predictive Power
The Q-square value provides insight into a model's
overall predictive performance by demonstrating its
ability to forecast outcomes that are not included in
its training set. The diagram shows that this model
has Q-square values of 0.253 for ICH and 0.786 for
DYN, indicating a fair predictive ability for
information not explicitly provided. Higher values
indicate superior accuracy, whereas increasing
values indicate improved predictive ability of the
model. The Q-square value is greater than 0.00,
0.25, and 0.50, as stated by [30], showing varying
levels of prediction accuracy in PLS path models. A
Q-square value between 0.00 and 0.25 indicates a
satisfactory level of prediction accuracy. A Q-
square value greater than 0.50 indicates a high level
of prediction accuracy. Due to the fact that it can
predict outcomes for DYN with a high degree of
accuracy and moderate accuracy for ICH, the model
is consequently capable of predicting results that
extend beyond its trained data.
4.4 Goodness of Fit
After thoroughly evaluating the model fit and
quality indices, Table 3 demonstrates that the
proposed model Fit and Quality Indices, Table 4
displays that the proposed model fits the original
data better than other models.

4.5 Normality Test
Table 5 displays significant deviations from the
normal distribution across all techniques, as
evidenced by the Kolmogorov-Smirnov test. This
divergence highlights the non-normally distributed
nature of the data, indicating that non-parametric
tests, like the Kruskal-Wallis test, might be a more
appropriate option for study, [33].

4.6 The Kruskal-Wallis test
The Kruskal-Wallis test was conducted to evaluate
the differences in rankings among various strategies
based on Excess Return. Results in Table 6 indicate
significant findings (H=223.704) with 3 degrees of
freedom and a p-value of 0.000, signifying
significant rank variations among the strategies.
This variation suggests statistically significant
differences in Excess Return across all strategies.
Mean ranks were used to determine performance
order, with the Dynamic Strategy having the highest
average rank (273.36), followed by Ichimoku
(235.85), Momentum (123.05), and Contrarian
(73.74). These results indicate that the Dynamic
Strategy tends to outperform the others, while the
Contrarian Strategy shows relatively lower
performance. The Kruskal-Wallis test provides
strong evidence that the integration of momentum
and Contrarian strategies, mediated by Ichimoku,
yields a new strategy distinct from its constituent
strategies.

Following the rejection of the null hypothesis in

test does not provide individual p-values for each
pair, a significant p-value (less than 0.05) indicates a
statistically significant difference in excess return
between those strategies.
5 Discussion
When evaluating the Momentum and Contrarian
strategies, Momentum achieves a higher excess
return compared to the Contrarian Strategy.
Investing in stocks based on their proximity and
recent performance relative to 52-week highs
significantly increases the likelihood of a positive
outcome, [34] These findings are in line with
research showing that gains gained from 52-week
highs include momentum gains [6], thus challenging
the notion of semi-strong form efficiency, [35].
Turning to Ichimoku, the Ichimoku Strategy
reveals its capacity to generate positive excess
returns that surpass the Momentum Strategy. This
methodology, which covers a wider range of bullish

and bearish signals, provides more accurate insights
into market trends and price conditions, [36]. Prior
studies have additionally confirmed the capacity of
Ichimoku to identify the commencement and
deduction of trends, [37], [38]. Similar to the
moving average method, Ichimoku is effective in
filtering out market noise and accurately identifying
trends. Its breakout methodology allows the initial
identification and precise conclusion of trends in
line with established technical trading principles,
[39], [40] The evidence substantiating the
superiority of the Ichimoku Strategy over the
Momentum Strategy proves the dependability and
uniformity of Ichimoku's effectiveness in
identifying trends. These results underscore the
critical role of Ichimoku in influencing market
dynamics and underscore its efficacy in facilitating
trading strategies.
The most appropriate approach for this
investigation is Dynamic Strategy, as indicated by
the results of the comprehensive analytics. For
market practitioners, the Dynamic Strategy presents
a promising approach, as it generates significantly
higher average excess returns than the Momentum,
Contrarian, and Ichimoku Strategies. The value of
10,717 clearly exemplifies the advantage of its
significant volatility. Market practitioners can
profitably optimize their return on investment by
utilizing a Dynamic Strategy. However, it is
imperative to remember that increased volatility also
increases risk similarly. To successfully and
sensibly manage risk, market practitioners must
have a strong understanding of these strategies.
The momentum path coefficients and contrarian
strategies exhibited unexpected and robust direct
effects in the opposite direction than anticipated.
Relationship Figure A2.1 and Figure A2.2
(Appendix) show the relationship between
momentum, contrarian, and dynamic strategies. This
shows that price movements follow an "S-curve"
shape, which means that prices may go backward
and forward around the highs and lows in a short
period. Both strategies make a weak contribution to
the influence of the dynamic strategy. Even
momentum strategies hurt the dynamic strategy's R-
square. They raise concerns about potential
overfitting, warn against hasty generalizations, and
underscore the need to understand the role of noise
traders in shaping financial market dynamics. In
[41] and [42], he emphasizes the importance of
gaining a deeper understanding of market dynamics,
which includes recognizing the impact of trader
noise and identifying anomalies such as
continuation and reversal patterns. The report
emphasizes the need to modify trading strategies in
response to changing market conditions and warns
against wrong conclusions or hasty judgments.
The use of anchoring and representativeness
heuristics can introduce ambiguity because they are
less consistent in generating continuation patterns
and may lead to price movement reversals.
Therefore, investors who rely on the highest or
lowest levels reached in the last 52 weeks should
thoroughly analyze the price movement patterns
before making a final investment decision. Errors in
predicting proximity to 52-week highs or lows can
lead to disposition effects, [43], [44], [45]. As a
result, when making trading decisions, traders are
often reluctant to use the highest or lowest prices
over the previous 52 weeks.
The lack of response to new data as the price
approaches the highest (lowest) level in the last 52
weeks is an important element in the continuation
patterns [6], [46], [47]. On the other hand, investors
often become too optimistic (pessimistic) about
stock prospects, [48]. Finally, a correction of this
overreaction can change the direction of price
movements [8], encouraging confident investors to
anticipate a reversal in the long term [15], [16], [49].
Understanding investor behavior and market
dynamics is critical to making informed trading
decisions.
Figure A2.3 (Appendix) shows a strong positive
relationship between Ichimoku's impact on dynamic
tactics and the J curve. This shows Ichimoku's
ability to detect emerging price trends and provide a
significant impact on dynamic trading techniques.
The highest and lowest prices over the past 52
weeks indicate an ongoing trend. This price
movement trend plays a role in connecting
momentum and contrarian strategies with Ichimoku.
Furthermore, a developing price movement trend
approaching the 52-week high or low level can form
a continuation or reversal pattern. Figure A2.4 and
Figure A2.5 (Appendix) show the important
relationship between momentum and the Ichimoku
indicator, resembling an S-shaped curve. In this
scenario, the price trend has two reversal points. The
Ichimoku indicator functions as a validator that
confirms the existence of a positive price trend.
Our results highlight the support of Ichimoku for
technical analysis and examine the influence on
trading strategies, which provides insight for
investors to improve investment decisions,
understand market behavior, and show support for
dynamic trading strategies like Ichimoku to enhance
stock market returns. Since it helps confirm long-
lasting patterns of price action, Ichimoku is likely to
find favor among dynamic strategy developers, i.e.,
practitioners and investors alike. Its capacity to send

a signal to buy at the onset of a trend and a signal to
sell at the termination of a trend makes it an even
more important indicator. In other words, Ichimoku
provides clearer signals to investors and traders than
the noisy moving average approach.
The low R-squared value of the Ichimoku
strategy indicates that momentum and contrarian
factors explain little of the variance, supporting that
its forecasting capabilities are very limited. But
when you add it to a momentum strategy, the R-
squared is much higher. That is to say, each
individual strategy may account for only a small
part of the behavior of a market, but together they
provide a stronger framework for how and why
prices may trend as they do. So, when combined,
these approaches will work to enhance its
efficiencies in mapping and
predicting market trends.
The Kruskal-Wallis test gives us some clues
about significant differences in excess returns
between different trading techniques (Momentum,
Contrarian, Ichimoku, and Dynamic strategies).
Performance-wise, the dynamic strategy is able to
achieve an optimal average score. The dynamic
strategies are statistically different from those of the
regulatory strategies. The research underscores the
potential effectiveness of combining these tools in
novel ways to create creative processes that
differentiate their components, with meaningful
implications for investors on how best to use them
to enhance financial performance. The average score
of dynamic strategy is the best which is in accord
with its best effect over the entire Quake test
protocol. Regulatory strategies differ in principle
from dynamic strategies and are statistically
different from regulatory strategies
The implications of these findings on research in
the further use of heuristics in strategy design to
improve earnings are significant. Technical
indicators or the Ichimoku could be potential
mediators or moderators in this process. These
logical heuristics include representativeness and
anchoring which can benefit traders when they
validate the performance of a trading strategy that
they have in their hands, Ichimoku strategies, for
example. This streamlines the trading process in real
time. The idea of this was that any new perspective
on the market could be used to gain a greater insight
into how psychological phenomena began to induce
further returns in a single act. By validating
Ichimoku trading strategies with strategies such as
representativeness and anchoring using the enriched
techniques of heuristics, traders can check the
viability of decisions and build heuristics in a
manner that makes them useful as practical tools.
This comprehensive approach underscores the
importance of integrating psychological insights
into investment practices to increase returns. Based
on these findings, market bias and fluctuations could
influence the 52-week holding strategy, potentially
diminishing its long-term effectiveness.
6 Conclusion
A comprehensive examination of four trading
strategies about the Indonesian stock exchange is
provided: momentum, contrarian, Ichimoku, and
dynamic. Through our comprehensive study, we
gain vital insights into trading methods and the
dynamics of the market. The dynamic approach,
which integrates the contrarian, momentum, and
Ichimoku techniques, demonstrated superior
performance compared to other strategies.
Considering the increasing unpredictability and
potential for high profits, this underscores the
importance of implementing prudent risk
management strategies. The important factor is that
Ichimoku acts as an intermediary in the relationship
between momentum, contrarian techniques, and
dynamic methods. It verifies the patterns of price
movements and provides timely indicators, which
influence the dynamics of the market and improve
trading tactics.
This function helps traders make more informed
decisions and better navigate the complexities of the
market. Understanding market dynamics and
adapting strategies is of utmost importance, as our
research shows. This underscores the potential
dangers associated with overgeneralization and
emphasizes the need for a deeper understanding of
market anomalies and investor behavior.
Furthermore, examining how changing market
conditions affect strategy efficacy can provide in-
depth information for traders and practitioners.
