# financial_sentiment_transformer_v2
|
| 13 |
+
|
| 14 |
+
## Overview
|
| 15 |
+
`financial_sentiment_transformer_v2` is a BERT-based model specifically fine-tuned on financial news, earnings call transcripts, and specialized social media feeds (e.g., StockTwits). It is designed to capture the nuanced language of market volatility and economic forecasting.
|
| 16 |
+
|
| 17 |
+
## Model Architecture
|
| 18 |
+
The model uses a standard **BERT-Base** (Bidirectional Encoder Representations from Transformers) backbone with a sequence classification head.
|
| 19 |
+
|
| 20 |
+
|
| 21 |
+
|
| 22 |
+
- **Pre-training:** Initially trained on general-purpose text (Wikipedia/BooksCorpus).
|
| 23 |
+
- **Fine-tuning:** Domain-specific fine-tuning on over 500,000 labeled financial snippets.
|
| 24 |
+
- **Nuance Handling:** Specifically trained to distinguish between general negativity and "financial negativity" (e.g., "Yields dropped" can be bullish or bearish depending on context).
|
| 25 |
+
|
| 26 |
+
## Intended Use
|
| 27 |
+
- **Algorithmic Trading:** Providing sentiment scores as features for quantitative models.
|
| 28 |
+
- **Market Intelligence:** Aggregating sentiment trends across thousands of daily news articles.
|
| 29 |
+
- **Risk Management:** Monitoring sudden shifts in public sentiment regarding specific tickers or sectors.
|
| 30 |
+
|
| 31 |
+
## Limitations
|
| 32 |
+
- **Temporal Bias:** Financial jargon changes rapidly (e.g., "transitory inflation"); the model may require retraining as economic cycles shift.
|
| 33 |
+
- **Sarcasm:** Like most NLP models, it struggles with highly sarcastic or ironic statements common in retail trading forums.
|
| 34 |
+
- **Short Context:** Limited to 512 tokens, which may be insufficient for long-form macroeconomic reports.
