Surveys African stock markets to find out if they are as efficient as developed markets, and follow the same “turn‐of‐the‐year” pattern as other markets. Compares Ghana, Zimbabwe and Nigeria, and focuses on the period between 1985 and 1995. Describes the environment of each, and computes monthly stock returns, testing them for seasonality. Finds evidence of the January effect only in Ghana, and there it is small. Notes that this may be the result of spillover from London.
