This study investigates the factors influencing investment decision-making within South Africa's financial markets, focusing on psychological, demographic, and external market elements. Drawing from Prospect Theory, the research reveals a deviation from traditional behavioral assumptions, highlighting that external market dynamics, rather than individual risk perceptions or demographic traits, predominantly guide investor behavior. Using a quantitative cross-sectional design, data were collected through structured questionnaires from 120 randomly selected South African investors aged 18 and older with market experience. Structural equation modelling assessed factors influencing risk perception and subsequently, investment behavior. The findings demonstrate that market-related variables significantly influence risk perception (? = 0.653, p < 0.001) and decision-making, aligning with the Efficient Market Hypothesis. In contrast to Prospect Theory's expectations, risk perception had no significant direct effect on investment choices (? = -0.009, p = 0.933). Cognitive biases and emotional influences exerted a moderate impact, while demographic characteristics, including gender, education, and experience, showed minimal influence on investment decisions, suggesting that practical market experience outweighs formal training. With robust construct validation (CR = 0.711 to 0.951), the study enhances the reliability and credibility of the findings. It highlights global regulatory frameworks as crucial for investor confidence. These results contribute to behavioral finance literature and support practical implications for policy, market transparency, and investor education. Future research should consider diverse populations and qualitative investors' perspectives.
