Abstract

This research investigates the intricate relationship between stock market fluctuations, particularly the DAX index, and macroeconomic indicators, such as German real GDP, during periods characterized by market bubbles. We extend the Johansen-Ledoit-Sornette (JLS) model by integrating fractional Brownian motion to effectively capture the long-memory properties inherent in volatility. Utilizing a FIGARCH (1,d,1) framework, our analysis reveals persistent volatility patterns within the DAX during speculative phases. Furthermore, we explore the impact of stock price movements on real GDP, demonstrating that sustained volatility significantly influences macroeconomic performance. Our findings highlight the necessity of considering financial market volatility in forecasting long-term economic stability, emphasizing the interdependence of financial markets and economic indicators in contemporary economic analysis. The result was further confirmed after being applied to the NASDAK index, the result is consistent with our finding.
