Ever since in the history of stock markets, financial theorists try to understand how investors take decisions under uncertainty in order to value stocks precisely and predict their future returns. Their wish to develop a consistent model gave raise for various theoretical approaches and empirical examinations. This work tries to give a short overview on the traditional theory of asset pricing and discusses the need for a paradigm change due to the recent development in the US and UK stock markets.

This work aims to provide a comprehensive overview of the traditional theory of asset pricing and examine the need for a paradigm shift in light of recent developments in the US and UK stock markets. The author explores the implications of these developments for the Efficient Market Theory and investigates alternative theories of share pricing that may better explain observed market behavior.

Zusammenfassung der Kapitel (Chapter Summaries)
The introduction provides a brief overview of the historical development of stock market theory and discusses the importance of understanding investor decision-making under uncertainty. Chapter 2 delves into the theory of market efficiency, examining its various forms and exploring the theoretical foundations of asset pricing models such as the Capital Asset Pricing Model (CAPM) and the Arbitrage Pricing Theory (ABT). Chapter 3 analyzes recent developments in the US and UK stock markets, particularly the emergence of market bubbles and the implications for the Efficient Market Theory. The chapter also explores evidence for additional factors influencing stock prices beyond traditional economic variables, such as seasonal effects, size effects, value effects, and momentum effects. It then introduces a behavioural approach to understanding market behavior. Chapter 4 explores alternative theories of asset pricing, such as the Model of Investor Sentiment and the Overconfidence Model, which attempt to incorporate investor psychology and cognitive biases into market analysis. The conclusion summarizes the key findings and discusses the implications for future research and investment strategies.
