Discussion of “Security Returns and Volume Responses around International Financial Reporting Standards (IFRS) Earnings Announcements”

Olibe (2016) uses price and trading volume responses around IFRS earnings disclosures for U.K. cross-listed firms trading as American Depository Receipts in U.S. equity markets to investigate whether such disclosures provide information to market participants over and above U.S. GAAP earnings disclosures. He finds evidence of significant price and trading volume responses for IFRS earnings disclosures, leading to the conclusion that market participants find that those disclosures facilitate trading in U.S. equity markets. This discussion focuses on the paper's incremental contribution to the literature and offers suggestions for improvements in the research design and analyses.
