This study empirically investigates the moderating effect of board activeness on the relationship between the structure of corporate ownership and firm performance. The objective was evaluated using the hierarchal panel regressions with data from non-financial companies of the Pakistan Stock Exchange from 2009 to 2018, operationalizing the ownership structure as state ownership, associated companies, foreign ownership, ownership concentration, institutional ownership, and family ownership, and firm performance as operating performance, financial performance, and stock market performance. The findings of the study revealed that operating, financial, and stock market performance were favorably influenced by the ownership stakes of the state, associated concerns, institutions, and foreigners. Family interests proved to be diverse for the firm performance. The isolated effect of the board consistently uplifted the firm productivity, but its interactional impact with all the ownership stakeholders postulated differential outcomes for internal and external performance. The study provides valuable insights for policymakers and investors to make optimal strategies to manage ownership interests and enhance value.
