We combine the global Hurst exponent and Morlet wavelet multi-resolution analysis to investigate the dynamic behavior of six selected stock markets in the Mediterranean region. Specifically, we employ the resonance coefficients and their power spectra to identify potential extreme movements and...

This paper shows that fluctuations in the U.S. equity returns signal information about the behavior of the returns of energy, metal and agricultural commodity futures. We find that asymmetry plays an important role in this relationship. In addition, while asymmetry seems to be more relevant for...

Market efficiency is among the foremost criteria for making investment decisions when foreign investors attempt to allocate their funds to emerging market assets. If the markets under consideration are efficient, quoted prices of the assets will serve as useful and reliable signals for capital...

We consider the problem of accurate market risk modeling for agricultural commodity products over heterogeneous investment horizons using copulas and wavelet methods. Our results indicate that the degree and structure of the dependence of daily commodity returns on the three market risk factors...

In this article, we show how the copula-GARCH approach can be appro- priately used to investigate the conditional dependence structure between the crude oil and natural gas markets as well as to derive implications for port- folio risk management in extreme economic conditions. Using daily price...

We analyze the empirical relationship between announcement effects and return volatilities of four CAC40 companies using intraday financial and event data from SBF-Euronext and Bloomberg, respectively. We estimate the daily component of the intraday volatility using a FIGARCH model and the...

We propose an enhanced regime-switching model to investigate the relationships between oil price surges and stock market cycles in five oil-dependent countries over the period from January 1989 to December 2007. Our model accounts for the joint effects of the WTI (West Texas Intermediate) and...

The paper employs an event study methodology to investigate the macroeconomic announcements effects on S&P500 and oil prices. Our results provide evidence of a significant impact of the US macroeconomic news on oil prices. This impact is split into two components, namely the direct effect...

This article investigates shift-contagion as defined by Forbes and Rigobon (2002) in 16 OECD member economies during most recent financial crisis i.e. global financial crisis (2008 -2009) and European sovereign debt crisis (2009-2012), using multivariate asymmetric dynamic conditional...

This article attempts to examine whether the equity premium in the United States can be predicted from a comprehensive set of 18 economic and financial predictors over a monthly out-of-sample period of 2000:2 to 2011:12, using an in-sample period of 1990:2-2000:1. To do so, we consider, in...
