The study looked at how the stock market in Nigeria affects the country's economic growth from 1987 to 2014. They used data on things like market size and trading volume to see if stock market performance causes economic growth or if it's the other way around. The results showed that the stock market performance influences economic growth in Nigeria, not the other way around. This means that changes in stock prices can give us clues about how the economy will do in the future. The study suggests that making sure information flows freely in the market can attract more investors and help the Nigerian economy grow.
