This research investigates the application of Word2Vec-style embedding techniques to financial markets to improve stock price prediction and embedding representations. The project developed neural network architectures to learn vector representations of 54 stocks across six sectors, testing whether stocks within the same industry exhibit similar embedding patterns analogous to semantic relationships in natural language processing. Multiple modeling approaches were implemented including 8-dimensional stock embeddings, crisis-weighted training methodologies, and transformer-based sequential prediction models.

Analysis of two years of market data revealed that systematic market risk dominates sector-specific patterns during 95% of trading periods, with clear sector divergence emerging only during crisis events. The key finding demonstrated that temporal attention mechanisms in transformer architectures significantly outperform static embedding representations, achieving a 47% improvement in prediction accuracy. This research contributes empirical evidence quantifying the relative influence of systematic versus idiosyncratic risk in daily stock movements and establishes the superiority of attention-based temporal modeling for financial prediction tasks.
