Excessive volatility hinders the stock market from playing its role of Mobilizing, financial resources from surplus units to deficit units and may cause a financial crisis. The research finding shows that interest rate has a negative relationship with stock market returns, while the inflation rate and exchange rate have a positive relationship with stock market returns. The conclusion therefore is, there is high and persistent volatility in the Nigerian stock market returns.
