The study used a model called CAPM to figure out how much money investors can make from stocks in Nigeria. They looked at data from 26 companies, the risk-free rate, and market returns from 2010 to 2016. The model showed that companies with higher market risk can give higher returns. This means that if a company is riskier, investors can make more money. It's suggested that companies in Nigeria should use this model to help investors make smart choices and grow their wealth.
