Hurst Exponent Dynamics & Financial Crisis Prediction

Source: Mark Vogel (VoglData) -- 42nd International Symposium on Forecasting, Oxford University, July 11, 2022. Academic research on Hurst exponent dynamics of cascadic wavelet filtered S&P 500 logarithmic returns (2000-2020). ~200,000 papers sampled quantitatively to extract state of the art across nonlinear dynamics, chaos theory, quantitative finance, and KF theory.

Core Finding: Fractal Trends, Not Long Memory

Mandelbrot's classical interpretation states that H > 0.5 reveals long memory in the data. This research contradicts that conception:
