# Explainable Stock Prediction with GRPO + RAG
---
## About this Space
This demo showcases a **financial NLP model** that predicts stock market reactions to news events while also providing a **natural language explanation**.
Unlike standard classifiers (which only output UP/DOWN/NEUTRAL), this model combines:
- **GRPO (Group Relative Policy Optimization)** → reinforcement learning to refine predictions through self-reflection.
- **RAG (Retrieval-Augmented Generation)** → retrieving past financial events to ground explanations in historical context.
The result: **predictions that are both accurate and interpretable**.
---
## How it works
1. **Input** → A financial news headline or event description.
2. **GRPO loop** → The model generates a prediction and, if wrong, reflect to improve future reasoning.
3. **RAG retrieval** → Relevant historical events are retrieved to enrich the explanation.
4. **Output** →
- Chosen Stock
- Price Prediction (UP/DOWN or percentage change)
- Explanation (short and clear, grounded in past events)
