Abstract

Purpose: This study examines the impact of voluntary disclosures and earnings management activities on stock price synchronicity between Sharīʿah-compliant and conventional business model firms. We investigate if Sharīʿah-compliant firms having additional voluntary disclosures and lower earnings management activities report a lower level of stock price synchronicity, or is it similar to conventional firms?
