Summary:	本研究旨在探討「最有可能的未知盈餘資訊」（首次報載財測調整或盈餘相關資訊）與「最有可能的已知盈餘資訊」（公司正式公布財測調整資訊）對股票報酬、交易量與波動性的影響。不同於早期相關的研究，本研究不但對盈餘相關資訊內容從事包含短期股價、交易量、波動性與長期股價的完整性調查，而且還分析投資人的認知失調與媒體的角色。本研究發現未知與已知的盈餘相關資訊皆提供有用的資訊內容至股票市場。此外，認知失調與處份效果對於盈餘相關資訊的投資人反應，具有重要的影響力。最後，媒體相關報導在投資人交易決策上扮演著關鍵的角色。 The aim of this study is to explore the effect of the most possible unknown (the initial media coverage of a certain company's earnings revision) and known (the official announcement of a certain company's earnings revision) earnings-related news on stock returns, trading volume, and return volatility. In comparison with previous literature, this study takes a further look at the informational content of earnings-related news, including the investigations on short-term stock price, trading volume, return volatility, and long-term stock price. Additionally, this study examines the investors' cognitive dissonance and the role of media. Empirical results indicate that both unknown and known earnings-related news provide useful information content to stock market. Moreover, cognitive dissonance and disposition effect have a great impact on investors' reaction to the announcements of earnings-related news. In the end, the media play an important role on investors' trading decision-making.
