Bank stock volatility, news and asymmetric information in banking: an empirical investigation
Résumé
The main objective of this paper is to empirically assess the issue of asymmetric information in banking within a framework based on the behaviour of bank stock prices. Following an event-study methodology for a sample of European listed banks during the Asian and Russian crises of 1997 and 1998, our results show that unexpected increases in bank stock volatility cannot be easily detected using standard proxies of bank asymmetric information derived from public data. Nevertheless, some indicators, particularly those based on the residuals of an earnings prediction model as suggested by Park [Journal of Regulatory Economics 16 (1999)], perform relatively well.
