Muslu, Volkan2018-11-302018-11-30May 20182018-05May 2018http://hdl.handle.net/10657/3458I use computational linguistic techniques to study the content, determinants, and stock market consequences of conference calls that are not held in conjunction with quarterly earnings releases (hereafter, non-earnings conference calls). I find that loss firms, growth firms, and firms with complex operations and a greater number of analysts following hold more both non-earnings and earnings conference calls. However, large firms and firms with more volatile earnings hold relatively more non-earnings conference calls than earnings conference calls. Firms with volatile earnings and greater operational complexity discuss more about earnings and investment-related topics in non-earnings conference calls. These results are consistent with the notion that firms facing greater informational problems hold more non-earnings conference calls. I also find that, controlling for other disclosure types, non-earnings conference calls incrementally explain quarterly abnormal stock returns, suggesting that they indeed help improve firms’ information environment.application/pdfengThe author of this work is the copyright owner.
