The aim of this article is to briefly review and make new studies of correlations and co-movements of stocks, so as to understand the "seasonalities" and market evolution. Using the intraday data of t...

The extreme event statistics plays a very important role in the theory and
practice of time series analysis. The reassembly of classical theoretical results
is often undermined by non-stationarity a...
Intraday Patterns in the Cross-section of Stock Returns
Intraday Patterns Cross-section Stock Returns

Stock prices are known to exhibit non-Gaussian dynamics, and there is much interest in under-
standing the origin of this behavior. Here, we present a model that explains the shape and scaling of the...
Can the Random Walk Model be Beaten in Out-of-Sample Density Forecasts? Evidence from Intraday Forei
Density forecasts GARCH Intraday exchange rate Jumps Maximum likelihood estimation Nonlinear time series Out-of-sample forecasts Regime-switching

It has been documented that random walk outperforms most economic structural and time
series models in out-of-sample forecasts of the conditional mean dynamics of exchange rates.
