Abstract
This paper introduces a new risk-on risk-off strategy for the stock market, which combines a financial stress indicator with a sentiment analysis done by ChatGPT reading and interpreting Bloomberg daily market summaries. Forecasts of market stress derived from volatility and credit spreads are enhanced when combined with the financial news sentiment derived from GPT-4. As a result, the strategy shows improved performance, evidenced by higher Sharpe ratio and reduced maximum drawdowns. The improved performance is consistent across the NASDAQ, the S&P 500 and the six major equity markets, indicating that the method generalises across equities markets.
Complexity vs Empirical Score
- Math Complexity: 2.5/10
- Empirical Rigor: 6.0/10 (capped from 7.5: no out-of-sample test; see penalty flags)
- Quadrant: Street Traders — practical and empirical, lighter on theory
Why this score: The paper focuses on implementing and testing a practical trading strategy using existing financial indicators (stress index, volatility, credit spreads) and an NLP tool (ChatGPT for sentiment analysis), with extensive backtesting across multiple markets and reported performance metrics (Sharpe ratio, drawdowns), indicating low theoretical math but high empirical implementation.
