The trading financial instruments in the capital market by Financial Service Firms (FSF) have generated return arising from changes in the prices of stock which exposed the firms to market risk. An effective market risk decision remains significant to determining stock return level realized from the volume and value of stock traded. This study examines the effect of market risk on stock return of listed FSF in Nigeria. The population of this study consists of fifty-six (56) financial service firms listed in the Nigerian Stock Exchange Market. In arriving at the sample size of twenty-nine (29) firms the purposive sampling technique and filtering criteria were employed. Data were sourced secondarily from the audited annual report of financial service firms, Nigeria Stock Exchange fact book, and other relevant financial service firms’ websites for period of twelve (12) years (2007-2018). Panel multiple regression technique of data analysis was applied using the ordinary least square estimator. The findings of the study revealed that book to market ratio as a proxy of market risk was insignificantly negative on stock return during the period under review. Net interest margin as a proxy of market risk revealed a significant positive effect on stock return during the period of review. Also, the study revealed that control variables of firm size, leverage had significant positive effects on stock return, though; the effect of monetary policy rate was positive but insignificant on stock return. The study concluded that a higher book to market ratio would reduce stock return and to a larger extent the reduction in stock return may not be affected significantly. It also concluded that a higher net interest margin would result to a higher stock return and vice versa. The study recommended that decision-makers and portfolio managers of financial service firms should employ appropriate risk strategies through derivatives, forwards, futures, swaps, options that can mitigate market risk in order to optimize return.
