Abstract

This study examines the effect of oil price shocks on energy stock returns in Nigeria for the period from January, 2000 to December, 2015. The study employs the Augmented Dickey-Fuller (ADF) and Kwiatkowski-Phillips-Schmidt-Shin (KPSS) tests for Unit root and a General Autoregressive Conditional Heteroscedasticity (GARCH 1, 1) modeling approach. The mean equation reveals that if oil price increases by one percent, energy sector stock returns will decrease by 74%. If exchange rate increases by $1, energy sector stock returns increases by about 0.78%. Furthermore, a unit increase in interest rate differential will cause a decrease in energy sector stock returns by about 25%. On the other hand, results of the variance equation, which captures volatility, suggest that oil price shocks and energy stock returns are negatively related.
