Brief Introduction

We opensource our AlphaFin series, now including AlphaFin dataset, the chat models trained on AlphaFin, namely StockGPT-Stage1 and StockGPT-Stage2, as well as Stock-Chain, the retrieval-augmented financial analysis framework.

We focus on two financial real-world tasks: Stock Trend Prediction and Financial Q&A. By integrating with RAG, we address the issue of hallucination of LLM’s output and LLM’s inability to generate real-time content.

• AlphaFin: contains traditional research datasets, real-time financial data, and handwritten CoT data, enhancing LLM’s ability in financial analysis.

• StockGPT-Stage1 is LLM fine-tuned with LoRA method on Fin. Reports and Fin. Reports CoT from AlphaFin, which is specialized for stock trend prediction task.

• StockGPT-Stage2 is continue trained with the research dataset, financial news, and StockQA datasets of AlphaFin, which is more conprehensive and capable of handling financial Q&A task.

Quick Start

Preparation

git clone https://github.com/AlphaFin-proj/AlphaFin.git
cd AlphaFin
pip install -r requirements.txt

Stage 1

bash scripts/stage1_trend_prediction.sh

Stage 2

bash scripts/stage2_financial_qa.sh

For Stage 2, we provide 200 sample data of news, research report and stock price documents for you to try this project, and more document data will be opened in this project as soon as possible after it is sorted out.

Dataset

Data source and preprocessing of the proposed AlphaFin datasets is shown in the figure. We ensure that our dataset covers a wide range of core financial analysis tasks, including NLI, financial QA, stock trend predictions, and so on. AlphaFin contains both Chinese and English datasets to eliminate potential linguistic biases. The English data primarily encompasses traditional financial and NLP-related tasks, while the Chinese data mainly contains financial research reports and stock predictions.

Dataset	Size	Input Len.	Output Len.	Lang.
Research	42K	712.8	5.6	en
StockQA	21K	1313.6	40.8	zh
Fin. News	79K	497.8	64.2	zh
Fin. Reports	120K	2203	17.2	zh
Fin. Reports CoT	200	2184.8	407.8	zh

Performance

Our Stock-Chain achieves the highest AR and maintains an upward trend, starting from 2023. It indicates the effectiveness of Stock-Chain in investment. Stock-Chain achieves the highest 30.8% of ARR demonstrating its effectiveness.
