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. |
