新聞報導在現今社會中為最便利與即時的資訊來源，也是公司與管理階層用來發布年度表現與其他重要消息的管道。本研究想要去找出新聞報導的內容與股票市場的反應之間的關連性，以及財務報表附註提供比新聞報導更多的其他資訊。 本研究以2013年度臺灣90家上市公司為樣本去探討股票市場與新聞報導及財報附註之間的關係。藉由內容分析法的方式去評估新聞報導與財報附註中的正向、負向情緒以及兩者之間的資訊差異以及兩者對股票市場的影響。藉由兩種不同的資訊來源，找出股票市場對於此兩者是否有不同的反應，並從中判斷兩種資訊內容的差異。 本研究發現新聞報導中的正向情緒與股票市場有正向的關連性，然而無法顯著證明在市場反應方面，財報附註能提供比新聞報導更豐富的資訊。 / Financial news articles are the most convenient and timely information in today’s world. Companies and managers can announce current year performance and other concurrent disclosures to investors and stakeholders by financial news articles. This study hopes to find the relationships between financial news articles and the stock market and the information content gap between financial news articles and footnotes to financial statements. This study uses 90 listed companies in TSE of 2013 to test stock market responses to the information content in the financial news articles and footnotes to financial statements. This study implements content-analysis technique, which count words for characterizing as optimistic and negative tone and helps to decide the abundancy of information content elaborated, to find the information content to stock market reactions and compare the information content gap between financial news articles and footnotes to financial statements. This study finds that optimistic sentiment expressed in financial news articles positively relates to the stock price movement. However, this study is unable to reach a conclusion that information disclosed in the footnotes to financial statements is significantly enough to represent the existence of information content gap as compared to financial news articles.

本研究主要探討台灣半導體產業供應鏈上游公司召開法人說明會是否會影響中下游公司之股價。本研究將法人說明會公布之資訊區分為財務資訊及非財務資訊，除探討財務資訊對供應鏈中、下游公司股價是否具影響效果外，亦探討財務及非財務的法人說明會資訊是否具有增額效果。實證結果顯示財務資訊在法人說明會召開前後一天與累積異常報酬呈現顯著正向關係，但非財務資訊卻呈現顯著反向關係，顯示非財務資訊會修正財務資訊所造成之效果。另外，資訊於供應鏈中移轉之距離越長，則移轉效果會越小，但若單純為好消息或壞消息，則移轉效果將增強。 / This research examines the influence of conference call information on the stock price of supply chain partners. The semi-conductor industries in Taiwan were used in this paper to examine the issue. I examined two kinds of information disclosed from conference calls: financial information and non-financial information. I first examined the information contained in conference calls for any effects on supply chain partners. Furthermore, I also examined to see if the non-financial information contains any additional effects to the supply chain partners. The empirical results show that the accumulated abnormal return of the supply chain partners is significantly positive related to the financial information around the conference call date. The accumulated abnormal return of the supply chain partners is significantly negative related to the non-financial information around the conference call date. The results show that both financial and non-financial information would influence the accumulated abnormal return of supply chain partners. The non-financial information contains additional information that revises the influence of the financial information.
