Abstract

This paper investigated the sensitivity of sectoral index returns on the Nigerian Stock Exchange to macroeconomic risk factors such as the spread between deposit and lending rates of banks, the slope of the yield curve, broad money supply, interest rates, exchange rates, inflation and the international price of oil. The study found that the banking, food and beverage, and insurance sectors were sensitive to some macroeconomic risk factors but not to others. The oil and gas sector was sensitive to the slope of the yield curve only. This study estimated the elasticities of macroeconomic factors in the Nigerian Stock Exchange using the sectoral indices. It is also one of the few studies that has tested the Arbitrage Pricing Theory (APT) on distinct sectors of the Nigerian Stock Exchange. A number of policy implications on prudential guidelines, sectoral inventions, direction of investments and hedging strategies are indicated.
