Paper Abstract

In the modern financial ecosystem, the inherent volatility and nonlinearity of stock markets necessitate predictive frameworks that transcend traditional quantitative indicators. Conventional forecasting methods often struggle to reconcile the noise of retail investor sentiment with the signal of corporate fundamentals, leading to suboptimal decision-making in automated trading and risk management.

In this paper, we propose a multi-modal fusion framework for stock price forecasting that harmonizes unstructured textual data, structured financial factors, and historical transaction sequences. At the core of our approach, FinBERT, a domain-specific transformer-based model, is proposed to quantify investor sentiment from Chinese stock forum while financial factor engineering is optimized through Information Coefficient (IC) analysis. To address the complexity

of market behavior, we introduce a hybrid architecture where a Transformer encoder captures long-range temporal dependencies across the fused feature space, while a Support Vector Regression (SVR) head ensures robust generalization. Experiments are evaluated on CSI 300 index stocks spanning 2014 to 2024. Our framework achieved an average R-squared exceeding 0.9 and an average RMSE of 0.0401, significantly outperforming individual baseline models and demonstrating robust generalization across diverse market sectors.
