The Impact of Fintech Innovation on Market Performance: A Comparative Analysis of Post-Pandemic US Fintech Stocks Nono Heryana, Nugraha Nugraha, Disman Disman, Mayasari Mayasari, Rini Mayasari, Solehudin Solehudin Studies in Business and Economics, 2026 This study examines whether fintech innovation is associated with superior market performance in the United States equity market during the July 2021 to December 2024 sample. Using daily data for eight publicly listed fintech firms representing heterogeneous models (digital lending, payments, crypto exchange exposure, trading platforms, and fintech-adjacent software) and a broad market benchmark, the analysis evaluates performance through risk-adjusted indicators, downside risk measures, and Capital Asset Pricing Model (CAPM) regressions. The results show substantial cross-sectional dispersion. A small subset of firms delivers positive and comparatively strong risk-adjusted outcomes, while several exhibit persistent underperformance and extreme drawdowns, indicating that fintech equities are not a homogeneous asset class in the study period. CAPM estimates yield economically small and statistically insignificant beta coefficients with near-zero explanatory power, implying that systematic market risk accounts for only a negligible share of fintech return variation. Instead, performance differences are consistent with firm-specific dynamics linked to business model structure and institutional integration. Robustness tests confirm that the main conclusions are stable across alternative specifications and validation settings. Overall, the findings indicate that innovation intensity alone is insufficient to guarantee sustained shareholder value without complementary institutional stability and risk discipline.
The Role of Convolutional Neural Networks (CNNs) in Forecasting Stock Prices of Green Companies: An Analysis of Time-Step Configurations Nono Heryana, Nugraha, Rini Mayasari 2024 9th International Conference on Informatics and Computing Icic 2024, 2024 The growing emphasis on sustainability has increased the role of green companies in the global economy, underscoring the need for accurate stock price forecasting to support informed investment decisions. This study examines the predictive capabilities of Convolutional Neural Networks (CNNs) for forecasting stock prices for green companies, focusing on the impact of various time-step configurations. By exploring different historical data windows, this research evaluates the CNN model’s performance through key metrics: Mean Squared Error (MSE), Mean Absolute Error (MAE), Rsquared ($\\mathrm{R}^{2}$), accuracy, precision, recall, and F1 Score. The results indicate that shorter time steps, particularly steps 5 and 15, achieve superior predictive accuracy and effectively capture short-term trends. The model demonstrated the highest performance with a timestep of 5, achieving the lowest MSE (0.001013) and MAE (0.023909), along with an $\\mathrm{R^{2}}$ of 0.977890 and an accuracy of $\\mathrm{9 1. 1 4 \\%}$. Cross-validation further confirmed the robustness and generalizability of the model, with an average accuracy of $73.11 \\%$ and balanced precision, recall, and F1 Score values. These findings validate CNNs as reliable tools for stock price prediction in a green economy and emphasize the importance of optimal time-step selection. This study offers valuable insights into enhancing predictive accuracy through the potential integration of additional market indicators and sentiment analysis, contributing to the evolving field of financial forecasting for sustainable investments.
