    Abstract: 本研究探討下列幾項重要主題:(1)台灣之管理者是否在自覺當「實際盈餘」之實現性有大意外前,提供預警訊息(如盈餘預測)給投資者?(2)有提供預警訊息之公司與未提供預警訊息之公司,其在特質上有何差異呢?(3)投資者對預測之預警訊息之反應如何呢?尤其對好消息或壞消息之反應是否不同呢?(4)除了提供盈餘預測此預警訊息外,台灣之管理者是否會提供其他營運性或非營運性之訊息(如:資本支出、資產出售利得、股利政策變動)等預警訊息給投資者呢?又投資者對這些資訊之反應如何呢?又投資者大盈餘意外之反應為何呢?< 經過實證研究結果,本研究得到下列幾項結論:(1)管理當局在實際盈餘之實現有大意外前,大部分並不會事先主動地提供預測預警之訊息給外界。(2)對壞消息公司而言,盈餘實現之意外性越大的公司,管理當局越可能提供預警訊息,但對好消息公司而言,盈餘實現之意外性並不是提供預警訊息的原因。(3)對好或消息公司而言,公司之規模越大,管理當局越可能提供預警訊息,且所揭露的警訊與盈餘也越直接相關。(4)高科技產業及受管制產業等產業別因素並非影響管理當局揭露政策的主要因素。(5)投資者對好消息之預警訊息有正向之股價反應,但對壞消息則未有負面之股價反應。(6)投資者對發布警訊之公司有部分之正面的評價。由於經理人的警示,提供了投資者從事投資決策的有用資訊,所以對發布警訊之公司而言,其股票報酬率會較高。
