This study investigates the performance of five models for forecasting the Egyptian stock market return volatility. We … examined also the ARCH effect to test the validity of using GARCH family to predict the volatility of market indices. The … between errors of volatility forecasting models, we found no significance difference between the errors of competing models …

We examine the performance of volatility models that incorporate features such as long (short) memory, regime …-t). Second, we perform a comprehensive panel forecasting analysis of the MSM models as well as other competing volatility models … over the alternative volatility models in terms of mean absolute forecast errors and that (iii) forecast combinations …

Stock prices declined abruptly in the wake of the Covid-19, reflecting both the deterioration of investors’ expectations of economic activity as well as the surge in risk aversion. In the following months, however, economic activity remained sluggish while equity markets bounced back. This...

In this study, we apply a rolling window approach to wavelet-filtered (denoised) S&P500 returns (2000–2020) to obtain time varying Hurst exponents. We analyse the dynamics of the Hurst exponents by applying statistical tests (e.g., for stationarity, Gaussianity and self-similarity), a...

We start this paper by presenting compelling evidence of short-term momentum in the excess returns on the S&P Composite stock price index. For the first time ever, we assume that the excess returns follow an autoregressive process of order p, AR(p), and evaluate the parameters of this process....

This article analyzed the presence of long memory in volatility in 5 Asian equity indices namely SENSEX, CNIA, NIKKEI …-sample forecast accuracy. The results confirmed the presence of long memory in both the return and volatility series for all the five … markets under study. Among the group, CNIA and STI showed most persistence in both the return and conditional volatility. In …

We build an equilibrium model to explain why stock return predictability concentrates in bad times. The key feature is that investors use different forecasting models, and hence assess uncertainty differently. As economic conditions deteriorate, uncertainty rises and investors' opinions...
