The spread of the global financial crisis of 2008/2009 was rapid, and impacted the functioning and the performance of financial markets. Due to the importance of this phenomenon, this study aims to explain the impact of the crisis on stock market behavior and interdependence through the study of the intraday volatility transmission. This paper investigates the patterns of linkage dynamics among three European stock markets—France, Germany, and the UK—during the global financial crisis, by analyzing the intraday dynamics of linkages among these markets during both calm and turmoil phases. We apply a VAR-EGARCH (Vector Autoregressive Exponential General Autoregressive Conditional Heteroscedasticity) framework to high frequency five-minute intraday returns on selected representative stock indices. We find evidence that interrelationship among European markets increased substantially during the period of crisis, pointing to an amplification of spillovers. In addition, during this period, French and UK markets herded around German market, possibly explained by behavior factors influencing the stock markets on or near dates of extreme events. Germany was identified as the hub of financial and economic activity in Europe during the period of study. These findings have important implications for both policymakers and investors by contributing to better understanding the transmission of financial shocks in Europe

<p>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 correlation model developed by Cappiello et al. (2006). The empirical analyses provide substantial evidence of shifts in the dynamic correlations and hence reconfirm shift-contagion during the global financial crisis that originated from U.S. However, there is no evidence in support of shift-contagion during the European sovereign debt crisis which originated from events in Greece. The results provide important implications for investors and policy makers.</p>

Using high frequency data we investigate the behavior of the intraday volatility and the volume of eight cross-listed French firms. There is a two hour "overlap" period during which French firms are traded in Paris and their related American Depositary Receipts (ADRs) are traded in New York. Using concurrent 15-min returns, this article examines the extent of market integration-defined as prices in both markets reflecting the same fundamental information-involving these firms. Our results suggest that these markets are not perfectly integrated. A significant rise in volatility and volume is observed during the two hour "overlap" period. This suggests the existence of informed trading. An error correction model (ECM) is then used to examine changes in prices of French firms in Paris and New York. These temporary changes appear to converge over time.
