Intra-Industry Information Transfers and Firm Value: Evidence from Ghana’s Banking Industry

The purpose of this study is to estimate the economic value of intra-industry information transfers within Ghana’s banking industry due to the collapse of seven banks. This is a short-term study with an event window [−10, +10] and an estimation period of 200 trading days. The event study methodology is adopted to estimate the cumulative abnormal return (CAR) gained by other rival industry banks as well as to calculate the cumulative average abnormal return (CAAR) for the entire Ghana Stock Exchange (GSE). The results of the study show that the collapse of the seven banks does convey information that the market uses in revising stock prices. However, most of the rival banks experienced an insignificant share price reaction. This insignificant reaction can be attributed to the fact that GSE is not efficient. The study recommended among others, for the GSE to be reformed to improve the efficiency of the market and secure the flow of information to market participants.
