This research study identifies, confirms, and integrates individual investors' psychographics within the contextual environment framework and the psychological biases. The study investigates the financial satisfaction level of investors and examines its relationship with investment decision-making. We empirically examined the conceptual framework by administering constructed instruments to the investors (n = 405). For examining the structural relationships, we have used covariance-based structural equation modelling (SEM). We have found that contextual factors like brand perception of investment, economic fundamentals, and individual financial needs are positively associated with investor sentiments. Additionally, we established that psychological biases like overconfidence, hindsight, illusion of control, loss aversion, and status quo are positively associated with investors' financial satisfaction. The study's findings suggest that more financially satisfied investors will likely have higher investment volume, higher investment frequency, and lower investment duration. This study's contributions enrich the behavioural finance literature and hold practical relevance for practitioners and policymakers.
