LITERATURE REVIEW
Conceptual Review
Behavioral Finance
Behavioural finance is a field that merges the disciplines of psychology and finance, challenging the traditional notion that investors make entirely rational decisions. Instead, it explores how cognitive biases and emotions influence financial choices. The traditional finance paradigm, based on the efficient market hypothesis (EMH), assumes that investors always act rationally and in their own best interest, utilizing all available information to maximize returns. However, this assumption has been called into question, especially as psychological factors such as fear, greed, and overconfidence come into play, influencing investors’ decisions in ways that deviate from rational behaviour (Kumari & Sar, 2017).
The emergence of behavioural finance provided an alternative perspective to these rigid assumptions by investigating the impact of psychological factors. One of the foundational ideas of behavioural finance is that investors do not always act based on logic but are instead influenced by cognitive biases such as overconfidence, anchoring, and herding behaviour. These biases lead to systematic errors in judgment and decision-making, which can result in suboptimal investment outcomes (Jayashree & Chitra, 2020). Overconfidence, for instance, may lead an investor to underestimate risks, while herd behaviour can cause market bubbles and crashes when individuals follow the crowd rather than conducting their independent analysis.
Behavioral finance also highlights the importance of emotions in investment decisions. For instance, the concept of “loss aversion” demonstrates how investors are more sensitive to potential losses than to equivalent gains, leading to an asymmetry in how they evaluate financial risks. This emotional response can cause investors to either sell assets too quickly to avoid losses or hold onto poor-performing investments in the hope that prices will rebound (Wamae, 2023). Behavioural finance, therefore, argues that emotions, in addition to cognitive biases, play a significant role in shaping financial behaviours.
The study of behavioural finance has gained momentum due to its ability to explain phenomena that traditional finance theories fail to address. For example, speculative bubbles, market overreaction, and investor panic during financial crises cannot be fully explained by rational decision-making alone. Behavioral finance, by incorporating human psychology into its analysis, provides insights into why such anomalies occur in financial markets (Arora & Kumari, 2023). In markets like Lagos State, where uncertainty and volatility are often present, understanding the psychological factors that influence investment behaviour is critical for both retail and institutional investors.

METHODOLOGY
Research Design
The research design refers to the overall strategy that outlines how the research will be conducted, addressing the specific objectives of the study (Saunders, Lewis, & Thornhill, 2019). This study adopted a quantitative survey research design, which is particularly effective for collecting numerical data that can be statistically analyzed to identify patterns and relationships among variables. The choice of a quantitative approach was justified by the need to quantify the influence of behavioral finance factors on investors’ decision-making in Lagos State. Quantitative research allows for a structured methodology where data can be gathered systematically through tools such as questionnaires, enabling the researcher to derive conclusions based on empirical evidence. By utilizing a quantitative design, this study aimed to obtain measurable data that would contribute to understanding the psychological influences on investment decisions, thus providing insights that could inform both practitioners and policymakers in the field of finance.
Population of the Study
The population of this study comprised individual investors residing in Lagos State, Nigeria. Lagos, being the financial hub of Nigeria, presents a diverse group of investors with varying backgrounds, investment strategies, and behavioral traits. The target population for this study was estimated to be 1,200 respondents, encompassing retail investors, institutional investors, and other stakeholders in the financial market. Justifying this sample size involved recognizing the need for a sufficient number of participants to ensure that the findings would be statistically significant and representative of the broader investor community. By focusing on Lagos State, the study sought to capture a comprehensive view of the behavioral finance landscape in a rapidly evolving economic context, thereby ensuring the research findings would reflect the complexities of investor behavior in this unique environment.

DATA PRESENTATION, ANALYSIS AND DISCUSSION
Data Presentation
Table 4.1 shows the distribution of questionnaires, where 109 out of the 120 distributed were returned and completed, representing 90.8% of the total. This high response rate indicates a strong level of engagement from the participants and provides a robust dataset for analysis. Only 9.2% of the questionnaires were either not returned or incomplete, suggesting minimal non-response bias. The low number of unreturned questionnaires (11) is insignificant enough to not affect the overall validity of the results.
With 90.8% of the distributed questionnaires being returned, this enhances the generalizability of the findings, as the majority of the sampled population participated in the study. A return rate of this magnitude ensures that the data collected reflects the views and behaviors of a large proportion of the intended respondents. The cumulative percent of 100% demonstrates that the entire sample was accounted for, either through completed returns or non-responses. This level of response is considered statistically acceptable and supports the reliability of subsequent analyses related to investment behaviors in Lagos State.

SUMMARY, CONCLUSION AND RECOMMENDATIONS
Summary of Findings
The study investigated the influences of cognitive biases, emotional factors, and social dynamics on investment decision-making among investors in Lagos State. The research aimed to identify how these factors affected the choices investors made in the financial market. The findings provided significant insights into the psychological and social elements at play in investment behavior.
The first key finding revealed that cognitive biases, particularly overconfidence and herd behavior, significantly impacted investors’ decision-making processes. The data indicated that a substantial number of respondents acknowledged that overconfidence led them to take excessive risks in their investments. Many investors expressed a tendency to follow market trends based on herd behavior rather than conducting independent analyses. This suggests that cognitive biases can skew rational thinking, causing investors to make decisions that may not align with sound financial principles. The study rejected the null hypothesis, confirming that cognitive biases are indeed influential in shaping investment choices in Lagos State. The implications of this finding emphasize the need for financial education aimed at fostering self-awareness regarding cognitive biases and promoting more rational decision-making approaches.
Suggestions for Further Studies
The study on the influences of cognitive biases, emotional factors, and social dynamics on investment decision-making among investors in Lagos State opens several avenues for further research. One significant area for future investigation is the exploration of additional cognitive biases that may affect investors in the Nigerian context. While this study focused primarily on overconfidence and herd behavior, other biases, such as anchoring, loss aversion, and framing effects, may also play critical roles in shaping investment decisions. Future studies could utilize qualitative methods, such as interviews or focus groups, to gain deeper insights into how these biases manifest in the behaviors of Nigerian investors, providing a more comprehensive understanding of the cognitive landscape in financial decision-making.
Another promising avenue for further research lies in the examination of demographic factors that may influence the relationship between cognitive biases, emotional factors, and investment decisions. Variables such as age, gender, education level, and socio-economic status could significantly affect how individuals experience and respond to cognitive and emotional influences in their investment behaviors. By conducting segmented analyses based on these demographic factors, researchers could identify specific trends and patterns that inform tailored investment education and advisory services. Understanding these nuances would enable practitioners to develop more effective strategies that address the unique needs of different investor segments.
