Forecasting multifractal volatility
WebOct 15, 2024 · From Fig. 3, the single peak values in the multifractal spectra of the CNY and CNH markets shows that multifractal features exist in the volatility of onshore and offshore exchange rates. The spectrum width of onshore and offshore exchange rate are 1.4746 and 0.9849 respectively, indicating that the onshore exchange rate has a higher … WebJun 15, 2024 · Lee et al. (2015) developed a multifractal value at risk (MFVaR) and showed that MFVaR can provide more stable and accurate forecasting performance in volatile financial markets. Brandi and Di Matteo (2024) proposed the scaled risk value (MSVaR) and improved the estimation of risk measures.

WebThis paper develops analytical methods to forecast the distribution of future returns for a new continuous-time process, the Poisson multifractal. The process captures the thick tails, volatility persistence, and moment scaling exhibited by many financial time series. It can be interpreted as a stochastic volatility model with multiple frequencies and a Markov latent … The multifractal model simplifies forecasting because it greatly reduces the volatility … H.
