用大模型分析新闻情绪，动态调整对冲策略
Dynamic Hedging Strategies in Derivatives Markets with LLM-Driven Sentiment and News Analytics
- 用大模型分析新闻、社交媒体等文本情绪
- 动态对冲比传统静态方法风险调整后收益更高
- 适合量化交易与风险管理从业者参考
动态对冲在衍生品市场中对风险控制至关重要，市场波动与情绪变化显著影响表现。本文提出一种新框架，利用大语言模型（LLM）进行情感分析与新闻解析，以支持对冲决策。通过分析新闻文章、社交媒体及财务报告等多源文本数据，该方法捕捉反映市场现状的关键情绪指标，实现基于持续情绪信号的实时对冲策略调整。在历史衍生品数据上的回测结果表明，该动态对冲策略相较传统静态方法获得更优的风险调整后收益。将大模型驱动的情绪分析融入对冲实践，显著提升了衍生品交易中的决策水平，展示了情绪感知型动态对冲在组合管理与风险控制方面的有效性。
原文摘要 · Abstract (English)
Dynamic hedging strategies are essential for effective risk management in derivatives markets, where volatility and market sentiment can greatly impact performance. This paper introduces a novel framework that leverages large language models (LLMs) for sentiment analysis and news analytics to inform hedging decisions. By analyzing textual data from diverse sources like news articles, social media, and financial reports, our approach captures critical sentiment indicators that reflect current market conditions. The framework allows for real-time adjustments to hedging strategies, adapting positions based on continuous sentiment signals. Backtesting results on historical derivatives data reveal that our dynamic hedging strategies achieve superior risk-adjusted returns compared to conventional static approaches. The incorporation of LLM-driven sentiment analysis into hedging practices presents a significant advancement in decision-making processes within derivatives trading. This research showcases how sentiment-informed dynamic hedging can enhance portfolio management and effectively mitigate associated risks.
