AbstractThis chapter analyses the fundamental principles of conventional finance, including the efficient market hypothesis (EMH), modern portfolio theory (MPT), and arbitrage pricing theory (APT), which have traditionally informed the comprehension of financial markets and investor conduct. These theories are based on the premise of rationality, which posits that investors digest information perfectly and that markets efficiently represent all available information. Although these models have made substantial contributions to portfolio creation, asset pricing, and risk management, their shortcomings become more apparent when confronted with enduring market oddities and behavioural inconsistencies. The chapter rigorously assesses the deficiencies of these conventional paradigms, especially their failure to explain phenomena such as market overreactions, speculative bubbles, and other departures from rational expectations. This discussion shifts to an examination of behavioural finance, including psychological concepts such as prospect theory, mental accounting, anchoring, overconfidence bias, and herd behaviour. These frameworks demonstrate the significant impact of cognitive biases and emotional reactions on financial decision-making, questioning the traditional beliefs of rationality and efficiency in financial markets. This chapter demonstrates the need of incorporating behavioural factors into finance theory via a combination of theoretical ideas and practical examples. This research provides a crucial foundation for comprehending the intricate relationship between rational models and actual human behaviour in financial situations. -

AbstractThis chapter rigorously assesses the contrast between conventional finance theories, including the efficient market hypothesis (EMH), and the tenets of behavioral finance. It analyses the constraints of traditional assumptions of rationality and market efficiency in elucidating phenomena such as the January effect, days of the week effect, and reversals. These persistent anomalies undermine the premise that market prices consistently represent basic values. This chapter emphasises the foundational contributions of behavioural finance pioneers, including Daniel Kahneman, Amos Tversky, and Richard Thaler, who established ideas like as prospect theory, heuristics, and the disposition effect. The chapter uses case studies, including Black Monday, to illustrate how biases like as loss aversion, overconfidence, and herd behaviour propel irrational decision-making in times of market distress. Empirical data contrasts conventional finance’s dependence on mathematical models with behavioural finance’s emphasis on cognitive and emotional factors. The chapter finishes by promoting a more holistic approach to comprehending market behaviour, recognising the interaction between rational decision-making models and the psychological inclinations that influence investor behaviours.

Chapter 4. Modern Behavioural Finance Theories
Kok Loang OoiModern behavioural finance theories have evolved to study the intricate interplay between human psychology and technology in financial markets. The adaptive market hypothesis proposes that markets are dynamic and adaptive, responding to changes in economic circumstances, technology, and cultural shifts. Machine learning and sentiment-based asset pricing models use advanced algorithms to evaluate human emotion and predict asset values based on real-time sentiment from social media and news. The behavioural economics of algorithmic trading reveals how human biases can infiltrate seemingly objective algorithms, leading to increased market volatility. Additionally, the investor overload theory explores how the constant influx of information can lead to irrational decision-making, while adaptive herding behaviour examines how social media and algorithms can drive collective investment actions. This chapter offers a fascinating look into the future of finance, where technology and human behaviour converge to create a dynamic and ever-changing market landscape.AI Generated
