1. Data Wrangling
In our quest to unveil the intricacies of the Saudi Arabian stock market, we embarked on a meticulous
data wrangling journey, employing the Tadawul stocks dataset as our primary resource. The dataset,
comprising 593,819 records and 14 fields, serves as a rich tapestry of information, detailing trading
activities across various stocks.
Our initial exploration of the dataset revealed a well-structured array of data, encompassing key trading
metrics such as opening, closing, high, low prices, and trading volumes. However, like any real-world
data, it was not devoid of imperfections. We identified missing values across several columns, notably
'open', 'high', 'low', and 'no_trades', albeit comprising less than 2% of the dataset. The presence of these
missing values necessitated a strategic cleaning process to ensure the integrity of my subsequent analyses.
Armed with a clear understanding of the dataset’s composition, we proceeded to meticulously clean and
transform the data. we expunged rows inundated with missing values, ensuring a cleaner dataset for
analysis. Recognizing the pivotal role of time-series analysis in stock market studies, we transformed the
'date' column to a datetime data type, paving the way for more granular and accurate temporal analyses.
In our pursuit of perfection, we corrected a typographical error, transforming 'sectoer' to 'sector', thereby
enhancing the dataset’s readability and user-friendliness. We also stripped any leading and trailing spaces
from column names, a subtle yet crucial step in preventing potential errors in future data manipulations.
Post-cleaning, the dataset now stands at 579,431 entries, bereft of missing values and primed for
exploratory data analysis. The transformation and cleaning processes have not only fortified the dataset's
robustness but have also laid a solid foundation for uncovering insights and trends within the Saudi
Arabian stock market.
As we transition to the exploratory data analysis phase, the dataset is in an optimal state, ensuring that the
insights derived in the subsequent stages are based on accurate and reliable data.

3. Moving Average Analysis
In our continuous endeavor to unravel the intricacies of the Saudi stock market, we directed our focus
towards analyzing specific stocks, with a keen interest in stock 1020, also known as Al Jazira Bank
(BJAZ). Utilizing a moving average analysis, we aimed to smoothen the price data over a specified
period, thereby mitigating the impact of short-term fluctuations and revealing potential trends and
patterns.
We employed two types of moving averages for our analysis: the Simple Moving Average (SMA) and the
Exponential Moving Average (EMA). The SMA was calculated over a 50-day and a 200-day period,
providing insights into both short-term and long-term trends. The EMA, calculated over a 50-day period,
was utilized to give more weight to recent prices, potentially offering a more responsive indication of the
stock’s movement.
𝑡
𝑆𝑀𝐴(𝑡) =
Σ𝑖 = 𝑡− 𝑛 + 1𝑝(𝑖)
𝑛
5
Where:
● SMA(t) is the simple moving average at time t
● P(i) is the price at time i
● n is the number of periods over which the average is calculated
We will calculate moving averages for the following time windows:
● 20 days (short-term)
● 50 days (medium-term)
● 200 days (long-term)
The 50-day SMA unveiled fluctuations that closely followed the stock's daily movements, offering a
smoothed representation of short-term trends. On the other hand, the 200-day SMA presented a broader
view, capturing the long-term trend and proving less susceptible to daily price changes. The 50-day EMA,
with its emphasis on recent prices, was quicker to react to price changes, offering a sensitive yet smoothed
portrayal of the stock's trajectory.
The crossovers between the short-term and long-term moving averages were particularly noteworthy.
Instances where the 50-day SMA or EMA crossed above the 200-day SMA were indicative of potential
upward trends, signaling a potential buying opportunity. Conversely, when the 50-day averages crossed
below the 200-day SMA, it could be interpreted as a bearish signal, suggesting a potential selling point.
The moving average analysis of stock 1020 served as a pivotal tool in deciphering the stock’s behavior,
providing valuable insights into both its short-term and long-term trends. By smoothing out the daily price
fluctuations, we were able to identify potential buying and selling signals, aiding in making informed
investment decisions. This analysis, while focused on a single stock, reflects the broader capabilities of
technical analysis in understanding and navigating the complexities of the stock market.
4. Time-Series Decomposition: Al Jazira Bank
To delve deeper into the specific characteristics of stock 1020 within the Saudi stock market, we
employed time series decomposition. This technique allowed us to break down the stock’s price data into
distinct components, namely trend, seasonality, and residuals, providing a comprehensive understanding
of its behavior over time.
6
We utilized the Seasonal Decomposition of Time Series (STL) method from the statsmodels library to
perform the decomposition. The STL method is particularly well-suited for this analysis due to its ability
to handle time series data with a seasonal component. The mathematical representation of the method can
be expressed as:
𝑌𝑡 = 𝑇 𝑡 + 𝑆 𝑡 + 𝑅 𝑡
Where:
● 𝑌𝑡 is the original time series data at time t.
●
𝑇𝑡 the trend component at time t.
●
𝑆𝑡 the seasonal component at time t.
●
𝑅𝑡 the residual component at time t.
This formula allows us to isolate and analyze each component individually, providing a clear
understanding of the stock’s underlying patterns and trends.
The trend component revealed the long-term movement of stock 1020, highlighting periods of growth and
decline. The seasonal component aimed to capture regular, cyclical patterns, though it was noted that
stock 1020 did not exhibit strong seasonality. The residuals, representing the noise or irregularities in the
data after extracting the trend and seasonality, offered insights into the stock’s volatility.
The time series decomposition of stock 1020 provided valuable insights into its behavior, isolating its
trend, seasonality, and residual components. This analysis enriched our understanding of the stock's
characteristics, aiding in the identification of potential investment opportunities and areas of risk. By
applying the STL method, we were able to break down the complexity of the stock’s movements, offering
a holistic and nuanced perspective essential for informed decision-making in the financial domain.
5. Time-Series Decomposition: Saudi Market
Building upon our individual stock analysis, we extended the time series decomposition to the entire
Saudi stock market, aiming to uncover underlying trends, seasonal patterns, and residuals that
characterize the market as a whole.
7
Employing the Seasonal Decomposition of Time Series (STL) method, we applied the same
decomposition technique used for stock 1020 to the aggregated closing prices of the entire market. The
formula used for this decomposition is the same as mentioned in the previous section.
The trend component showcased the overarching direction of the Saudi stock market, providing insights
into periods of prosperity and downturns. Unlike stock 1020, the market exhibited a clear seasonal
pattern, reflecting the cyclical nature of trading activities. The residual component highlighted the
market’s volatility, with certain periods showing heightened irregularities.
The application of time series decomposition to the entire Saudi stock market unveiled the market’s
complex behavior, segmented into trend, seasonality, and residuals. This comprehensive analysis not only
enriched our understanding of the market’s dynamics but also underscored the necessity of employing
advanced analytical techniques, such as the STL method, in financial analysis. By doing so, we were able
to derive meaningful insights, contributing to our overarching goal of demystifying the Saudi stock
market and providing a solid foundation for informed investment decisions.
6. Time-Binned Analysis
To further our exploration of the Saudi stock market, we conducted a binned time period analysis,
categorizing the market's historical data into distinct time bins. This approach allowed us to examine the
market's behavior across different eras, providing insights into its evolution and highlighting potential
patterns or trends.
The market data was divided into three primary bins based on specific time periods:
● Early Period (2001-2008): Representing the early 2000s and leading up to the global financial
crisis.
● Mid Period (2009-2015): Covering the post-crisis recovery and a significant part of the 2010s.
● Modern Period (2016-2020): Reflecting the most recent trends and developments in the market.
8
For each bin, we calculated descriptive statistics, including mean, median, standard deviation, minimum,
and maximum values, for key market indicators such as stock price, trading volume, and trading value.
The analysis revealed distinct characteristics for each time period:
● Early Period (2001-2008): This era showed a relatively lower average stock price and trading
activity, reflecting the market's nascent stage and lower liquidity.
● Mid Period (2009-2015): There was a noticeable increase in trading activity and stock prices,
indicating the market's recovery post the 2008 financial crisis and a phase of growth and
stabilization.
● Modern Period (2016-2020): This period exhibited the highest average stock prices and trading
volumes, highlighting the market's maturity and increased investor participation.
Visualizations in the form of box plots provided a clear representation of the data distribution across the
bins, helping to identify outliers and understand the spread of the data.
The binned time period analysis offered a granular view of the Saudi stock market's behavior over the past
two decades, uncovering patterns and trends unique to each era. By segmenting the data into distinct time
bins, we were able to observe the market's evolution, from its early stages to its modern form. This
analysis not only contributed to our comprehensive understanding of the market but also served as a
crucial step in assessing the market's investment potential and identifying periods of significant change or
stability. Through this approach, we have enhanced our ability to make informed decisions and offer
robust recommendations in the realm of financial investment and market analysis.
7. Crisis Analysis: Black February
The Saudi stock market, like many others worldwide, has experienced its fair share of tumultuous periods.
One of the most notable crises in its recent history is Black February in 2006, a time when the market
witnessed significant turbulence. In our analysis, we aimed to unravel the impact of this crisis on the
market, comparing the performance of key indicators during the pre-crisis, crisis, and post-crisis periods.
To conduct a comprehensive analysis, we divided the time frame into three distinct periods:
● Pre-Crisis: January 2001 to January 2006
● Crisis: February 2006
● Post-Crisis: March 2006 to December 2020
9
For each period, we calculated the average stock price, trading volume, and trading value, providing a
clear picture of the market's performance and behavior. This approach enabled us to quantitatively assess
the impact of the crisis and understand how the market evolved in its aftermath.
The results of our analysis painted a vivid picture of the market's response to the crisis:
● Pre-Crisis: The market exhibited steady growth, with increasing stock prices and trading activity,
reflecting investor confidence and a robust economy.
● Crisis: February 2006 marked a stark contrast, with a significant drop in stock prices and a spike
in trading volume and value, indicating panic selling and market instability.
● Post-Crisis: The market experienced a period of recovery and stabilization, with a gradual
increase in stock prices and a normalization of trading activity.
By visualizing these findings through line charts, we were able to capture the dramatic shifts in market
behavior, providing a clear and intuitive understanding of the crisis's impact.
The crisis analysis of Black February 2006 has provided us with invaluable insights into the resilience and
volatility of the Saudi stock market. Through careful examination of key market indicators across
different periods, we have unraveled the market's response to crisis conditions, gaining a deeper
understanding of its behavior and dynamics. This analysis not only sheds light on the market's historical
performance but also equips us with the knowledge to better navigate future market uncertainties,
ultimately contributing to more informed and strategic investment decisions.

8. Hypothesis Testing
In order to quantitatively validate our observations from the crisis analysis, we engaged in hypothesis
testing, focusing on the impact of Black February on the Saudi stock market. Our goal was to establish if
there were statistically significant differences in the market's performance across the pre-crisis, crisis, and
post-crisis periods.
We set our hypotheses as follows:
● Null Hypothesis (𝐻0): there is no significant difference in the average stock price, trading
●
volume, and trading values across the three periods.
Alternative Hypothesis (𝐻1): there is a significant difference in the average stock price, trading
volume, and trading values across the three periods.
To test these hypotheses, we employed Analysis of Variance (ANOVA), a statistical method used to
compare the means of three or more samples to understand if at least one of the sample means is
significantly different from the others. The formula for the F-statistic in ANOVA is given by:
𝐹 =
𝐵𝑒𝑡𝑤𝑒𝑒𝑛−𝑔𝑟𝑜𝑢𝑝 𝑉𝑎𝑟𝑖𝑎𝑏𝑖𝑙𝑖𝑡𝑦
𝑊𝑖𝑡ℎ𝑖𝑛−𝑔𝑟𝑜𝑢𝑝 𝑉𝑎𝑟𝑖𝑎𝑏𝑖𝑙𝑖𝑡𝑦
=
𝑀𝑆𝐵
𝑀𝑆𝑊
We applied the ANOVA test to the average stock price, trading volume, and trading value across the three
periods. Our analysis yielded the following F-statistics:
● Average stock price: F = 5.67, p < 0.05
● Average trading volume: F = 9.14, p < 0.05
● Average trading value: F = 8.23, p < 0.05
The p-values being less than 0.05 led us to reject the null hypothesis for all three indicators, suggesting
that there are indeed significant differences in the market's performance across the different periods.
Through rigorous hypothesis testing, we have statistically substantiated our observations from the crisis
analysis. The significant F-statistics across all key market indicators unequivocally point to the profound
impact of Black February on the Saudi stock market. This not only validates our previous findings but
also reinforces the importance of statistical rigor in market analysis. By employing hypothesis testing, we
have added a layer of statistical validity to our study, ensuring that our conclusions are not just based on
visual observations but are also backed by solid statistical evidence. This approach enhances the
credibility of our analysis and provides a strong foundation for future studies aiming to unravel the
complexities of market behavior during crisis periods.

14. Volatility Forecasting for Stock 1020 in the Financial
Sector
In this comprehensive analysis, we focus on stock 1020 within the Financials sector of the Saudi Arabian
stock market. Our goal is to understand its price movements, identify potential outliers, and provide a
volatility forecast.
We start by filtering and sorting the dataset to ensure accuracy in our subsequent analysis. The dataset is
checked for missing values in the 'close' price column, with no missing values found, indicating data
completeness.
Through the calculation of the Interquartile Range (IQR), we identify potential outliers in the closing
prices. The dataset from November 2005 to November 2006 showcases several data points considered as
outliers, where the closing prices experienced significant fluctuations.
A line plot with highlighted outliers provides a visual representation of the closing prices and the
identified outliers, offering a clear view of the price movements and the periods of heightened

The Monte Carlo simulation is a powerful statistical technique that allows us to understand the behavior
of an uncertain parameter. In the context of finance and stock prices, this method can be used to simulate
the potential future movements of a stock’s price, helping investors to make informed decisions based on
a range of possible outcomes.
In our analysis, we focused on stock 1020 within the Financials sector. We filtered the dataset to include
only the last four years of trading data for this stock and calculated the daily returns. Using these daily
returns, we conducted 1000 simulations of the stock’s price over the next 8 trading days.
The simulation results were then used to calculate various descriptive statistics, providing insights into the
potential future movements of the stock’s price. Additionally, we identified the worst-case, median-case,
and best-case scenarios from our simulations.
● Price Movement Simulation: The Monte Carlo simulations generated a wide range of potential
price movements for stock 1020 over the next 8 trading days. The visualization of these
simulations highlighted the stock’s volatility and the various paths it could take.
● Descriptive Statistics: The calculated mean, median, standard deviation, minimum, and maximum
for each day provided a comprehensive view of the potential price movements. The increasing
standard deviation over the days reflected the growing uncertainty in the stock’s price as we
looked further into the future.
● Scenario Analysis:
○ Worst-Case Scenario: This scenario showed a consistent decrease in the stock’s price over
the 8 days, indicating a potential risk for investors.
○ Median-Case Scenario: This scenario presented a more stable and modest change in the
stock’s price, possibly aligning with the stock’s typical behavior.
○ Best-Case Scenario: This optimistic scenario showed a significant increase in the stock’s
price, presenting an opportunity for substantial gains.

Risk Management: Investors can use the worst-case scenario to understand the potential risks associated
with holding stock 1020, allowing them to make informed decisions about whether to hold, sell, or hedge
their positions.
Investment Decisions: The median-case and best-case scenarios provide insights into the potential upsides
of investing in stock 1020, helping investors to weigh the potential rewards against the risks.
Strategic Planning: By understanding the range of potential outcomes, investors and traders can plan their
strategies accordingly, setting appropriate stop-loss and take-profit levels to manage their risk and
maximize their returns.
Portfolio Diversification: The insights from the Monte Carlo simulation can also aid investors in making
decisions about portfolio diversification, ensuring that they are not overly exposed to the risks associated
with stock 1020.
In summary, the Monte Carlo simulation has proven to be an invaluable tool in our extensive analysis of
the Saudi stock market. By simulating a wide array of possible future scenarios for stock prices, based on
historical volatility and returns, we have gained deeper insights into the potential directions the market
could take.
The simulation's probabilistic approach, grounded in the principles of geometric Brownian motion, has
enabled us to paint a vivid picture of future market dynamics, taking into account the inherent
uncertainties and fluctuations of the stock market. The resulting distribution of possible stock prices
provides us with a range of outcomes, helping to quantify the risk and highlight potential rewards, thereby
aiding investors in making more informed and strategic decisions.
Furthermore, the Monte Carlo simulation has complemented our other analytical methods, such as the
GARCH model for volatility forecasting, by offering a forward-looking perspective. While the GARCH
model helps us understand and predict future volatility based on past behavior, the Monte Carlo
simulation takes this a step further by translating that volatility into a spectrum of possible future stock
prices.
By integrating these advanced statistical and probabilistic methods, we have enhanced our ability to
navigate the uncertainties of the market, providing a robust framework for risk assessment and investment
planning. The insights derived from the Monte Carlo simulation, therefore, do not just offer a glimpse into
the potential future of the Saudi stock market, but rather equip us with the knowledge and analytical
prowess to make strategic decisions in the face of uncertainty, ensuring that we are well-prepared to
capitalize on opportunities and mitigate risks as we navigate the complexities of the financial world
