This paper investigates the relation between corporate ownership and corporate performance of listed companies in Nigeria, a foremost Sub-Saharan African country during the period [2002][2003][2004][2005][2006][2007]. The data is obtained from the firms" annual reports and accounts and the Nigerian Stock Exchange daily performance reports. The combination of 70 firms and six-year period studied provides a balanced panel with 420 observations for panel data analysis. The results from the ordinary least square (OLS) regression analyses show that there is a strong connection between foreign ownership structure and firm performance. Foreign ownership structure is found to exhibit significant improvements in firm performance; it adumbrates eclectic competitive advantages in ownership, control and internalization respects over other types of ownership structure. We find no statistically significant relation between concentrated ownership and firm performance. Insider or managerial ownership, however, exhibits significant decline in firm performance. These findings are consistent with the view that firm performance is a negative predictor of insider ownership. We also find support for the notion that management is apathetic to holding equity stakes in their underperforming firms.
