The document summarizes a study on the relationship between corporate governance and firm performance for companies listed on the Karachi Stock Exchange. The study developed a Corporate Governance Index (CGI) using 22 governance factors across three categories and analyzed its correlation with Tobin's Q valuation metric for 50 companies over three years. The results found a positive significant relationship between higher CGI scores and Tobin's Q, indicating better corporate governance is associated with higher firm valuation. Sub-index analyses found board composition and ownership factors most significantly linked to performance.
