This study proposes a multimodal hybrid framework that integrates corporate disclosure texts, stock prices, and market indicators for enhanced stock price prediction and portfolio optimization. Long Short-Term Memory (LSTM) networks are employed to capture temporal dependencies from stock and market data, while FinBERT is used to extract semantic embeddings from disclosure documents. These heterogeneous modalities are fused within a classification model to evaluate the significance of corporate and market events on stock movements. Experimental results reveal substantial performance variation across industries, motivating industry-specific investment strategies. Portfolio optimization based on these multimodal strategies achieves superior riskadjusted returns compared to benchmark approaches.
