According to the "Administrative Measures for Information Disclosure of Listed Companies" (CSRC Order No. 40) promulgated on January 30, 2007, to standardize information disclosure behaviors of issuers, listed companies, and other information disclosure obligors, listed companies shall disclose relevant information promptly, accurately, and completely, including prospectuses, fundraising prospectuses, listing announcements, periodic reports, and temporary reports.
Timely and accurate corporate announcements can provide investors with signals of positive or negative market impacts and influence real-time trading. Retrospective analysis of historical corporate announcements enables academic investigations into market reactions, investor sentiment, and corporate performance. In the era of new media, market responses to corporate announcements have become more rapid and intense, all of which can be quantified through big data analytics.
