Arabic Financial Stock Prediction Approach
Based On Deep Learning Technique
Maryam Mohamad Al-Zawahra, Mohammad Bany Baker, Mohammad Zayed Almuiet
Abstract: The prediction of the financial stock market based on the published financial news is considered to be a major issue in the financial field,
particularly in light of the significant contents of the news article. Nevertheless, the prediction technique used to gather useful terms from the Arabic
financial news has been elusive and is yet to be established. Therefore, this study aimed to develop and propose a practical solution by which the Arabic
stock market can be predicted through the analysis of event terms from the Arabic financial news articles. The approach obtained 89.68% accuracy in
such prediction, indicating the usefulness of the approach. This is a unique and pioneering study that applies machine learning method to predict Arabic
stock market. The study has several implications to the financial field and profession.

1 INTRODUCTION
Stock market is a crucial component of the financial market, in
terms of the interactions and dealings that take place through
it. Investor and speculator circles in the market are looking to
raise profitability by the analysis of the information provided
concerning the market. In this regard, one of the main market
information sources is the financial news articles and such
articles have been extensively utilized for analysis among
investors [1]. In the current era of data, referred commonly as
the Big Data Era, news articles have shown a monumental
increase, and faced with a considerable pile of news articles,
institutions have been increasingly turning to high processing
computer power for analysis. Support systems predictions can
help investors sift through noises and reach wise and informed
decisions as contended by [2]. Therefore, this study proposes
a model to conduct news articles analysis for accurate
predictions to solve the issue.

Moreover, predictive measures
can basically be divided into two major analyses, which are
technical and fundamental analysis. They are distinct from
each other according to the data input, and also, the former is
used with historic market data, while the latter is used for news
concerning country, society, firm, and the like. Majority of prior
literature has conducted technical analyses based on
quantitative historic market data and the traders‘ inclination
towards the use of technical qualitative techniques. In relation
to this, basic data is more difficult to use as the data input,
particularly if it lacks structure. However, basic data may be
obtained from structured and numerical sources such as
macro-economic data or regular financial reports provided by
the governments and their banks. Such basic data aspect has
not been extensively studied, although authors do rarely
illustrate their predictive value (e.g., [3]).
Basic data in the form of unstructured text is the most difficult
aspect to examine and is thus, the direction that the study
adopted. This may be exemplified by the textual information
available in social media, blogs, forums and news [3]. In the
field of technical analysis, researchers have primarily made
use of mathematics for the analysis of historical stock price
patterns, and eventually predict stock prices for the future.
Many algorithms have been adopted for such purpose in
different forms; for instance, multiple kernel learning in [4],
deep learning in [5] and [6], stepwise regression analysis in
[7], among others. Despite the clear and consistent outcomes
achieved, it remains challenging to predict stock prices in an
accurate manner through the sole use of historical prices
owing to the unpredictable events that can influence such
prices. Meanwhile, in [8] study, the authors employed
fundamental analysis of natural language processing (NLP) in
their attempt to analyze financial news and statements from
the firm, with the ultimate aim of predicting future stock trends
(uptrend and downtrend). Specifically, NLP‘s bag-of-words
technique is the most often used method for the features
extraction from the news articles, measuring each word‘s
presence and transforming text information into vector spaces
with their help. Following this step, machine learning
algorithms are used to establish the relationship between word
patterns and the movements of stock prices. Regardless of the
accurate ability of bag-of-words technique in several studies
(e.g., [5], [8]), one crucial element has been left out in the
prediction of directions and that is the sentiment of the article.
In relation to this, a specific phase in concerns the
interpretation of the investors of the published news articles
after which they are transformed into positive/negative
sentiments to reach decisions as to whether stocks should be
purchased, held or sold on the basis of the interpretations of
sentiments. Lastly, the aggregate of the market prices is used
on each investor‘s actions, after which, this is represented in
the final price trends. In other words, based on the above, the
combination of sentiment analysis and natural language
processing could prove effective. Lastly, machine learning
algorithms are used to obtain information on the relationship
between extracted news features and stocks trends. More
recently, Deep Neural Networks (DNNs) – a category of
machine learning – has garnered success after another in
different fields, for instance, in speech recognition in [9] and
computer vision in [10]. In this line of study, neural networks
have become popular owing to the image-based applications
