Abstract:	本研究利用事件研究法探討2001年1月1日至2018年12月31日這期間，在發生重大事件或是自然災難性事件後，對台灣上市股價的影響為何，探討異常報酬的類股及變化量，以及重大天然災害或是重大事件是否具有資訊內涵效應，故在發生這類事件後，投資者需採取哪些不同投資策略。實證結果顯示，在事件日之後股票市場的報酬往往牽動著相關類型的股票，影響類股的波動會因為公司的體質而有所差異，若是體質良好的公司，波動通常不會起伏太多。　　This research adopts event study method to investigate the effect of significant events or natural catastrophic incidents on stock price of listed companies in Taiwan between January 1st, 1990 and December 31st, 2018.
