It is designed to capture the nuanced language of market volatility and economic forecasting. ## Model Architecture The model uses a standard **BERT-Base** (Bidirectional Encoder Representations from Transformers) backbone with a sequence classification head. - **Pre-training:** Initially trained on general-purpose text (Wikipedia/BooksCorpus). - **Fine-tuning:** Domain-specific fine-tuning on over 500,000 labeled financial snippets. - **Nuance Handling:** Specifically trained to distinguish between general negativity and "financial negativity" (e.g., "Yields dropped" can be bullish or bearish depending on context). ## Intended Use - **Algorithmic Trading:** Providing sentiment scores as features for quantitative models. - **Market Intelligence:** Aggregating sentiment trends across thousands of daily news articles. - **Risk Management:** Monitoring sudden shifts in public sentiment regarding specific tickers or sectors. ## Limitations - **Temporal Bias:** Financial jargon changes rapidly (e.g., "transitory inflation"); the model may require retraining as economic cycles shift. - **Sarcasm:** Like most NLP models, it struggles with highly sarcastic or ironic statements common in retail trading forums. - **Short Context:** Limited to 512 tokens, which may be insufficient for long-form macroeconomic reports.
