Employing data from IR firms during the years 2011 to 2015, we identify the association between firm performance and IR disclosure quality. Further, we examine the way in which the quality of IR disclosure improves the value relevance of summary accounting information (i.e., the market value of equity) and can create value. Specifically, we show the positive relation between firm performance and the quality of IR disclosure. Further, an examination shows that the level of the quality of IR disclosure is more significant when firms tend to exhibit a higher value relevance of summary accounting information (i.e., the book value of equity and earnings). Finally, more effective use of IR has resulted in abnormal stock returns being positively associated with earnings quality.BusinessFinanceJournal Article1878-33844717558000023662
