The Efficient Market Hypothesis (EMH) theory commonly referred to as the Random Walk Theory is one of the most debated topics in finance studies over the years because of the growing concerns that investors can trade on the available information so as to make abnormal profits in the market. EMH states that the price of a security (current stock prices) in the market reflects all the available information on its fundamental value at all times, hence investors cannot make any abnormal profits above the market prices using this information. EMH explains why changes in security prices occur and how those changes happen, hence very crucial to investors as they make their investment decisions in the security market. Many investors both domestic and global invest on securities that are undervalued as they expect their value to increase in the future. Other investors including investment managers also stress that they are able to choose those securities that can outperform the market prices with the core objective of gaining more profits. EMH argues that none of these assumptions is effective because the advantage gained is less than the transaction costs incurred such as research costs on the information hence not in a position to outperform the market price of these securities

Zusammenfassung der Kapitel (Chapter Summaries)
Finance 1: The Existence of Efficient Market Hypothesis (EMH) in the International Financial Markets: This chapter introduces the Efficient Market Hypothesis (EMH), outlining its central argument that security prices fully reflect available information, preventing investors from consistently earning above-market returns. It discusses the implications of this theory for investor behavior and decision-making, emphasizing the competitive nature of financial markets and the difficulty of consistently outperforming the market due to transaction costs. The chapter sets the stage for subsequent discussions on the validity of the EMH in light of real-world events.
Finance 2: The Efficient Market Hypothesis (EMH) and Random Walk Theory: This chapter delves deeper into the EMH, connecting it to the Random Walk Theory. It highlights the ongoing debate surrounding the EMH and its implications for investors seeking abnormal profits. The chapter explores the core argument that price changes primarily reflect the arrival of new information and emphasizes the importance of market efficiency in international financial markets due to strong competition among profit-maximizing investors. The chapter lays groundwork for further exploration of scenarios where market efficiency is questioned.
Finance 3: Market Efficiency and Mis-priced Stocks: This chapter examines the concept of market efficiency in the context of identifying and exploiting mis-priced stocks. It highlights the competition among investors to detect such opportunities and the costs involved in this process. The chapter introduces the idea of "trust market prices" as a core tenet of the EMH, where no investor can consistently beat the market. It also acknowledges criticisms of the EMH based on the occurrence of major financial crises, laying the foundation for the later analysis of the 2007 global financial crisis and the Eurozone crisis.
Finance 4: The Euro Zone Crisis and the EMH: This chapter analyzes the Eurozone crisis and its implications for the EMH. It links the crisis to the earlier 2007 global financial crisis, highlighting how the use of public funds to bailout banks negatively impacted revenue growth and led to an insolvency crisis. The chapter connects the crisis to the theory of economic time, illustrating the difficulties of unifying currencies across states with differing monetary systems and political structures. This section challenges the notion of perfectly efficient markets, especially in periods of significant economic turmoil.
Finance 5: Market Realism, Investor Sentiment, and the EMH: This chapter explores the market realism theory, which emphasizes the importance of market information in fostering market efficiency. It discusses the challenges of exploiting mispricing for abnormal profits due to associated costs. The chapter further delves into the implications of financing risks in international markets, where security prices may diverge from their economic values due to investor sentiment and emotional decision-making. It also touches on issues such as investor overreaction and underreaction to new information and the resulting price reversals, questioning the assumption of perfectly rational actors within the EMH framework.

What is the Efficient Market Hypothesis (EMH)?
The EMH is a central theory in finance that proposes that asset prices fully reflect all available information. This implies that it is impossible for investors to consistently achieve above-average returns because any available information is already incorporated into the price.
How does the text relate the EMH to real-world events?
The text uses real-world events, such as the 2007 global financial crisis and the Eurozone crisis, to examine the validity and limitations of the EMH. It analyzes how these crises challenged the assumptions of perfect market efficiency.
What is the role of investor sentiment in the context of the EMH?
The text explores how investor sentiment and emotional decision-making can influence market efficiency and lead to deviations from the EMH’s predictions. It examines instances of overreaction and underreaction to new information.
What are the criticisms of the EMH discussed in this text?
The text addresses criticisms of the EMH, highlighting the occurrences of major financial crises and the role of investor psychology as evidence against perfectly efficient markets. The limitations of the EMH’s assumptions of rational actors and perfectly competitive markets are also discussed.
What are the key terms and concepts covered in this text?
Key terms and concepts include the Efficient Market Hypothesis (EMH), Random Walk Theory, International Financial Markets, Market Efficiency, Financial Crises (2007 Global Financial Crisis, Eurozone Crisis), Investor Sentiment, Market Realism, Arbitrage, Risk, and Capital Market Liberalization.
Who is the intended audience for this text?
This text preview is intended for academic use, providing a structured overview for analyzing themes related to the Efficient Market Hypothesis in international finance.
