This study examines the information content on audiovisual record of conference call by using conference call characteristics, namely, call length and linguistic-based call tone, after compulsory disclosure of self-holding conference call audiovisual files from June 2013 in Taiwan. Using the latter half-year data of 2013, our empirical results indicate that the stock price reaction is positively associated with the greater call length and positive conference call tone in question and answer section. Our evidence highlights the importance of communications and interactions between management and participants in conference question and answer section as conference call becomes a venue for information dissemination in the capital market.
