GPT-InvestAR:通过大型语言模型分析年度报告增强股票投资策略

GPT-InvestAR: Enhancing Stock Investment Strategies through Annual Report Analysis with Large Language Models

Udit Gupta

AI总结:

本文提出GPT-InvestAR框架,利用大型语言模型分析公司年度报告生成洞察,结合历史股价数据训练机器学习模型,步进测试显示其相对S&P500具有超额收益,并开源代码。

摘要:

上市公司的年度报告包含有关其财务状况的重要信息,有助于评估对公司股票价格的潜在影响。这些报告内容详尽,通常长达甚至超过100页。分析这些报告即使对单个公司而言也很繁琐,更不用说分析所有存在的公司。多年来,金融专家已变得相当熟练,能相对快速地从这些文件中提取有价值的信息。然而,这需要多年的实践和经验。本文旨在利用大型语言模型(LLMs)的能力,简化所有公司年度报告的评估流程。由LLM生成的洞察被汇编成量化风格的数据集,并用历史股票价格数据进行增强。随后,以LLM输出作为特征训练一个机器学习模型。步进测试结果显示,相对于S&P500收益,该方法展现出有前景的超额收益。本文旨在为该方向的未来工作提供框架。为促进此目标,代码已作为开源发布。

英文摘要:

Annual Reports of publicly listed companies contain vital information about their financial health which can help assess the potential impact on Stock price of the firm. These reports are comprehensive in nature, going up to, and sometimes exceeding, 100 pages. Analysing these reports is cumbersome even for a single firm, let alone the whole universe of firms that exist. Over the years, financial experts have become proficient in extracting valuable information from these documents relatively quickly. However, this requires years of practice and experience. This paper aims to simplify the process of assessing Annual Reports of all the firms by leveraging the capabilities of Large Language Models (LLMs). The insights generated by the LLM are compiled in a Quant styled dataset and augmented by historical stock price data. A Machine Learning model is then trained with LLM outputs as features. The walkforward test results show promising outperformance wrt S&P500 returns. This paper intends to provide a framework for future work in this direction. To facilitate this, the code has been released as open source.
