Dynamic Hedging Strategies in Derivatives Markets with LLM-Driven Sentiment and News Analytics

2025-04-05

AI Summary

To address the challenge of dynamically hedging volatility- and sentiment-driven risks in derivatives markets, this paper proposes the first large language model (LLM)-driven real-time sentiment-aware dynamic hedging framework. Methodologically, it integrates fine-tuned LLMs with prompt engineering to enable fine-grained sentiment modeling across heterogeneous financial texts—including news articles, earnings reports, and social media. A closed-loop pipeline is established comprising streaming news parsing, sentiment signal extraction, and adaptive optimization of delta-hedging parameters. The key contribution lies in the first deep integration of LLM-powered sentiment analysis into the dynamic hedging workflow, overcoming the limitations of conventional static or purely volatility-based models. Historical backtesting demonstrates substantial improvements: a 37% increase in Sharpe ratio and a 29% reduction in maximum drawdown relative to Black–Scholes static hedging and GARCH-VaR benchmarks.

Abstract

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.
