Abstract
This project takes a critical look at the effectiveness of the capital markets in Saudi Arabia by comparing the conventional Efficient Market Hypothesis (EMH) with new developments in behavioral finance, especially the effects of digitization. The research examines the impact of digital transformation, including the use of platforms like Tadawul, Muqassa, and Edaa on market transparency, information dissemination, and trading behavior. It also examines the existence of market anomalies such as momentum effects, investor sentiment biases and overreaction within the Saudi capital market. An overview of empirical research and some regional case evidence shows how digitization has improved price discovery processes and revealed new behavioral patterns among retail and institutional investors. The results are practically relevant to portfolio managers and corporate financial decision-makers, especially with the Saudi Arabian Vision 2030 financial sector development plan. The paper ends with practical recommendations on how to use digital innovation to enhance market efficiency.

1.0 Introduction
The efficiency of capital markets in processing information has been a central issue of financial economics for decades. The Efficient Market Hypothesis (EMH) states that the prices of assets already incorporate all existing information and, therefore, investors should not be able to consistently outperform the market by using that same information (Vasileiou, 2022). Nevertheless, with the passage of time, the different anomalies in the market behaviour, such as abrupt overreactions, herd mentality, and momentum trading, have prompted researchers to consider other theories. This has led to the emergence of behavioral finance that considers the role of emotions, psychology, and social aspects in financial decisions and market performance (Risman et al., 2023).
A new turn of this debate has been witnessed in the recent years with the rapid growth of digital technology, especially in the emerging economies such as Saudi Arabia. As the financial sector is being modernized as a part of the Vision 2030, the nation is experiencing a shift in the market operation and investor behavior because of the emergence of new trading platforms and digital services (Hidayat et al., 2022). This project aims to critically assess the efficiency of capital markets in Saudi Arabia through comparing the traditional EMH views with behavioral finance approaches and paying specific attention to the role of digitization.
The paper highlights how Tadawul, Muqassa, and Edaa have improved market operations through facilitation of transactions, transparency, and information access. It also examines whether these improvements have reduced pricing anomalies or even in some cases encouraged new types of speculative behavior. The study focuses on the common anomalies of momentum trading, overreaction, and sentiment-based price movements within Tadawul in light of recent studies and market trends. Lastly, the project explains the implications of these findings to portfolio management and corporate financial strategies in Saudi Arabia, and provides practical recommendations on how to improve the market efficiency through smarter policy and technology use.
2.0 Background
The concept of capital market efficiency is central to financial economics and describes the degree to which asset prices incorporate all known information at any point in time (Goldstein, 2022). In a perfectly efficient market, no investor can systematically earn returns that exceed the average without incurring extra risk. This concept can be summarized in the Efficient Market Hypothesis (EMH) which Downey (2024) states that it is available in three forms namely weak, semi-strong, and strong, based on the kind of information that is thought to be already priced in assets. The assumptions of EMH are however challenged by numerous market anomalies including momentum effects, overreaction of investors and herd behavior (Ahmed, 2025). These anomalies have prompted researchers to consider behavioral finance, which is a discipline that studies the impact of cognitive biases, emotions, and social factors on financial decision-making and market performance.
The capital market in Saudi Arabia has grown rapidly within the last twenty years, particularly since the launch of Vision 2030. The Saudi Stock Exchange (Tadawul) and the related platforms such as Muqassa and Edaa have digitized the market infrastructure (Ramady, 2021). Jaloliddin (2023) defines digitization in this context as the application of high-tech digital technologies to enhance the speed of trading, its transparency, and access to real-time market information. Although these developments are meant to enhance market efficiency, Noch & Rumasukun (2024) argue that they also create new issues since the quicker the information is spread, the more the behavioral tendencies like speculation and herd trading will be increased.
Despite the current studies on market efficiency in Saudi Arabia, most of them are aimed at testing EMH without taking into consideration the whole behavioral finance approach or even looking at the role of digitization in particular. Little empirical research has been done on the effects of digital financial platforms on market anomalies or investor behavior in the Saudi market. This gap offers a good reason to conduct this study, which will assess whether digitization has enhanced market efficiency or merely altered the nature of market inefficiencies, providing useful information to policymakers and investors alike.
3.0 Research Objectives

- To compare the predictions of the Efficient Market Hypothesis (EMH) with insights from behavioral finance in explaining investor behavior within the Saudi capital market.
- To examine the role of digital platforms such as Tadawul, Muqassa, and Edaa in improving market operations, information dissemination, and transaction efficiency.
- To investigate the presence and persistence of market anomalies, including momentum trading, investor overreaction, and sentiment-driven volatility, in the Saudi capital market.
- To assess how digitization has influenced investor psychology, trading volume, and market volatility in Saudi Arabia.
- To provide practical recommendations for portfolio managers, corporate financial decision-makers, and policymakers on enhancing market efficiency through digital infrastructure and behavioral awareness.
