The Future of Finance: Artificial Intelligence's Influence on Behavioral Investment Decisions

1. Introduction To Behavioral Finance

Behavioral finance, an interdisciplinary field amalgamating insights from psychology and economics, delves into the intricate relationship between human psychology and cognitive biases and their influence on financial decision-making. This branch of study departs from the conventional financial theories like the Efficient Market Hypothesis (EMH), which presuppose that market participants unfailingly act with perfect rationality, consistently making decisions solely in their best economic interests. In contrast, behavioral finance acknowledges the prevalent human tendency to deviate from rationality, propelled by a plethora of psychological factors that wield substantial impact on both individual investment choices and broader market outcomes. A fundamental aspect of behavioral finance is its focus on the behavior of investors and how their biases and emotions can exert influence on financial markets (Shambora & Rossiter, 2007). Its roots can be traced back to seminal works like Prospect Theory, formulated by Kahneman and Tversky in 1979 (Yang, 2016). Prospect Theory laid the foundation for behavioral finance by introducing the concept of decision-making under risk and highlighting the systematic cognitive biases that individuals exhibit when confronted with uncertainty.

Cognitive style, an essential facet of behavioral finance, pertains to an individual's consistent pattern of processing and organizing information, which in turn can significantly influence decision-making and problem-solving (Chudry et al., 2011). This concept of cognitive style stands distinct from cognitive capacity, typically measured by IQ or creativity levels. Understanding an individual's cognitive style can provide crucial insights into their decision-making processes and help elucidate why specific biases and heuristics may be more pronounced in certain individuals. Another pivotal avenue explored by behavioral finance is the notion of misvaluation within financial markets. Several behavioral models predict that misvaluation of firms can exhibit commonality, resulting in positive movement among stocks sharing similar characteristics and negative comovement among stocks with dissimilar traits (Hirshleifer & Jiang, 2010). This misvaluation may stem from irrational investor enthusiasm for specific stock attributes or from overconfidence in the interpretation of private information. The ramifications of behavioral finance extend broadly across the entire finance landscape. It brings to the forefront the profound impact of psychological phenomena on financial markets, effectively challenging the underpinnings of classical finance theory, which posits that prices remain uninfluenced by behavioral factors (Almansour, 2020). Contrarily, behavioral finance contends that emotional and cognitive biases can indeed sway asset prices, thus introducing inefficiencies into markets and presenting potential opportunities for investors.
