Abstract

This paper empirically investigates the asymmetric effect of news on the time-varying beta of selected banks from seven European countries during the current crisis period and also during the pre-crisis period. The paper applies daily data from thirteen large banks from France, Germany, Greece, Ireland, Italy, Portugal and Spain. The sample size ranges from 2002 to 2013 and includes the current global financial crisis (2007-2013). The BEKK GARCH model is first employed to estimate the time-varying beta and then linear regression is applied to investigate the asymmetric effect of news on the beta. The asymmetric effects are investigated based on both market and non-market shocks. Results show that some evidence of market efficiency can be witnessed via non-market shocks, however the market shocks indicate that the European banks foster a significant amount of uncertainty leading to asset mispricing. Results also show a clear rift in terms of quality of results between France and Germany taken as a group and the rest of the countries under study. These results shed light on the level of market efficiency and hedging strategies.
