The findings from this research shows a coefficient of the Zenith bank Low stock price at (0.546945) and high stock price at (0.453562) which indicates that low stock price is insignificant because is less than α = 0.05, while high stock price of greater than α = 0.05 is significant to predict the Zenith bank stock price.
