Stock price crash risk is one of the most significant risks associated with the firm. Therefore, it is important to consider the factors which may influence the price crash risk. Various factors of corporate governance found to have an impact on the stock price crash risk. The ownership structure of the firm is a critical attribute of corporate governance. This study's objective is to determine the impact of two types of ownership of a company (managerial ownership and institutional ownership) on its stock price crash risk. To examine whether a firm's ownership structures have an association with stock price crash risk, the multiple linear regression model applied on the panel data of 190 companies listed on KSE for the year 2009-2018. The results of this study show that there is a significantly positive relationship between the institutional ownership and stock price crash risk. However, no association found between managerial ownership and price crash risk. These results imply that the percentage of institutional ownership should be reduced in the firm's ownership structure to reduce the firm's stock price crash risk.
