Abstract

The dynamic and growing interdependent nature of equity markets across the world has elicited the interest ofinvestors and researchers alike. This study examines the dynamic interactions between the Nigerian stock marketand selected regional and global equity markets spanning eight years, from 2011 to 2018, using daily index data.The generalised impulse response function was used alongside the Toda and Yamamoto Granger causality test toinvestigate the short-run dynamic linkages, while the normalized Johansen vector error correction estimatesserved to assess the long-run linkages given the existence of cointegration. Findings from the study revealed thatthe UK and the Ghanaian stock markets exert significant long-run impact on the Nigerian stock market, whilevagaries from the US tend to exert more influence on the Nigerian stock market in the short-run. The studyrecommends that more regional efforts are needed to enhance the integration of stock markets in West Africa. Thefindings have implications for national and regional policymakers as well as portfolio investors.
