Particularly, before the event, companies are more frequently cited as a source of the news for positive events. This indicates that companies seek to capitalize the positive impact of the favourable subsequent disclosures. After the occurrence of abnormal returns, companies are more often a source of the news for negative cases, seeking to mitigate their impact. Additionally, after negative events companies are more frequently mentioned in the news with a positive content than they are mentioned before.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-subheading\">Social implications<\/jats:title><jats:p>The new approach of this study allows the companies' information stakeholders (namely investors and regulators) to become more informed and critical in the analysis of news coverage and its sources.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-subheading\">Originality\/value<\/jats:title><jats:p>As far as the authors of the paper know, this is the first study that addresses the question of eventual asymmetric behaviour of companies\u2019 communication in face of positive and negative abnormal returns.<\/jats:p><\/jats:sec>","DOI":"10.1108\/ccij-11-2019-0132","type":"journal-article","created":{"date-parts":[[2020,7,17]],"date-time":"2020-07-17T04:22:56Z","timestamp":1594959776000},"page":"248-264","source":"Crossref","is-referenced-by-count":8,"title":["Corporate communication and media coverage of abnormal returns \u2013 evidence from the Portuguese capital market"],"prefix":"10.1108","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3861-8554","authenticated-orcid":false,"given":"Carlos Francisco","family":"Alves","sequence":"first","affiliation":[]},{"given":"Ana Lu\u00edsa","family":"Silva","sequence":"additional","affiliation":[]}],"member":"140","reference":[{"issue":"1","key":"key2021022408370811000_ref001","doi-asserted-by":"crossref","first-page":"31","DOI":"10.1080\/00014788.2015.1025254","article-title":"Investor relations, information asymmetry and market value","volume":"46","year":"2016","journal-title":"Accounting and Business Research"},{"issue":"1","key":"key2021022408370811000_ref002","doi-asserted-by":"crossref","first-page":"241","DOI":"10.1111\/jofi.12109","article-title":"Who writes the news?
