Abstract

This paper rummages the stock price fluctuations in periods of corporate acquisition and control. The paper became pertinent to provide information to the corporate board of directors and investors to improve decision making by understanding the inherent fluctuations and the concomitant uncertainties during periods of corporate acquisitions and control negotiations. The main aim of the paper is to examine if there is a significant difference in stock price fluctuation before and during periods of corporate acquisition. The methodological approach is quantitative and used the statistical T-test of difference in mean stock price differences before and during periods of SABMiller acquisition. It also applied the cointegration analysis to establish a correlation in stock price between the acquiring company and the company under acquisition. The analysis was tested at an alpha of 0.05 and results from the statistical analysis disclosed a significant difference to the degree of P<0.001 on two-tailed significance test and showed that stock price fluctuation was higher during the acquisition period than before. Similarly, the cointegration test showed a significant correlation in stock price movement between the purchasing company and the company under acquisition at a P<0.001. The Granger causality test was applied to determine the direction of causality, and the analysis showed that the AB Inbev stock price trend influenced the stock price movement in SABMiller during the period of acquisition with a P=0.008. The paper concludes that at least within the case examination, the news of corporate acquisition may trigger investment uncertainties, which may reverberate on stock price fluctuations. The paper brings insight to the corporate board of directors toward improved negotiation of acquisition or merger prices and compensations given the price fluctuations that acquisition news may trigger on the merging companies’ stocks.
