In this article, we analyse the co-movements of daily stock prices and government bond prices during the last 25 years, in major Western stock markets, extending previous results to take into account the impact of the current crisis. Our results confirm that bonds are viewed as instruments for improving portfolio diversification in periods of high volatility and falling stock market levels, which is when such diversification is most needed. The possibility of using government debt in portfolios as a means of hedging during times of financial crisis became especially apparent in the crises of 1997, 2001 and 2008. Nevertheless, during the current one, this diversification quality of bonds has disappeared in countries like Italy or Spain, which are also affected by sovereign debt issues.

In this paper we present a technique to obtain the time-varying covariance matrix for several time series for nearest neighbour predictors. To illustrate the use of this technique, we analyse the time-varying variances and correlations between the daily returns on two equity stock market indexes, the New York Stock Exchange (NYSE) and the Madrid Stock Exchange Index (MSEI).
We measure the connectedness in EMU sovereign market volatility between April 1999 and January 2014, monitoring stress transmission and identifing episodes of intensive spillovers from one country to the others. We first perform a static and dynamic analysis to measure the total volatility connectedness in the entire period using a framework recently proposed by Diebold and Yilmaz (2014). Second, we use a dynamic analysis to evaluate the net directional connectedness for each country and apply panel model techniques to investigate its determinants. Finally, we examine the time-varying behaviour of net pair-wise directional connectedness at different stages of the recent sovereign debt crisis.

This paper measures the connectedness in EMU sovereign market volatility between April 1999 and January 2014, in order to monitor stress transmission and to identify episodes of intensive spillovers from one country to the others. To this end, we first perform a static and dynamic analysis to measure the total volatility connectedness in the entire period (the system-wide approach) using a framework recently proposed by Diebold and Yılmaz (2014). Second, we make use of a dynamic analysis to evaluate the net directional connectedness for each country and apply panel model techniques to investigate its determinants. Finally, to gain further insights, we examine the timevarying behaviour of net pair-wise directional connectedness at different stages of the recent sovereign debt crisis.

New evidence is presented on the sudden shift in the sentiment of market participants with the outbreak of the sovereign debt crisis. Since volatility reflects the extent to which the market evaluates the arrival of new information and provides useful insights into the dynamics of EMU sovereign debt markets, we analyze their spillovers. To that end, we first examine the unconditional patterns during the full sample (April 1999-January 2014) using a measure recently proposed by Diebold and Yilmaz (2012). Second, we make use of a dynamic analysis to evaluate net directional volatility spillovers for each of the eleven countries under stud and to determine whether core and peripheral markets present differences both before and during the crisis periods. Finally, we apply a panel analysis to empirically investigate the determinants of net directional spillovers of this kind. Our results suggest that slightly more than half of the total variance of the forecast errors is explained by shocks across countries rather than by idiosyncratic shocks. Besides, they give further support to the idea that during the pre-crisis period, most of the triggers in the volatility spillovers were central countries - peripheral countries imported credibility from them - while during the crisis, peripheral countries became the dominant transmitters.
