The efficiency of securities market has generated a lot of controversy over four decades in finance and economic discussions leading to some people accepting or rejecting the efficient market hypothesis. Hence this paper examines the growing body of empirical research on efficient market hypothesis on the Nigerian capital market for the past twelve years (2010-2021). The paper particularly surveys empirical research and specialized literature as it relates to the Nigerian capital market. The paper is purely empirical research that have been published in various academic journals on the Nigerian capital market. Findings from the empirical research show that there has been no consensus on the efficiency of the Nigerian capital market. However, the market seems to be efficient in the weak-form. The conclusion of this paper is that there are inherent difficulties in testing for market efficiency in developing countries capital market due to certain market imperfections that could affect the informational efficiency of the market.

This study examines the impact of globalization on Nigerian financial development with particular reference to foreign direct investment, trade openness, exchange rate, government expenditure, interest rate and inflation. The statistical data used for the study were obtained from Central Bank of Nigeria publications and [Statistical Bulletin 2020] and [World Development Indicators 2020]. The study employed the autoregressive distributed lag (ARDL) model. Major findings from the study show that foreign direct investment, trade openness and government expenditure have a positive and significant impact on financial development in Nigeria while exchange rate, interest rate and inflation rate have a negative significant impact on Nigerian financial development. It is recommended that Nigeria must face the challenges of globalization. For a country to belong to the race, major changes and restructuring are imperative, hence, Nigeria must develop the internal structure and the will to adopt those policies that brought about the benefits from globalization.
