中文摘要 |
有關股票市場弱式效率性的研究,因研究方法、研究期間的不同,其結論亦不相同。因此,股票市場效率性至今尚未有定論,而股票市場效率性的問題也被Brealey, Myers and Marcus(2004)列為現今七大財務學尚未解決的問題之一。本研究應用時間數列ARIMA模型,以四個不同階段,檢定台灣股市是否符合弱式效率市場假說。研究結果顯示,四個階段中的所有時期之股市收益率均可以建立適當的ARIMA模型,而這個結果也顯示台灣股市並不符合弱式效率市場中歷史資訊無效的假說。 |
英文摘要 |
The conclusions of the studies relating to efficient market hypothesis (EMH) were inconsistent because of the different research methods and sample periods of time. Therefore, the efficiencies of stock markets are still a problem today. Moreover, this issue was thought one of the seven major unknown problems in financial field by Brealey, Myers and Marcus (2004). This study applied the time series model to test the weak form efficiency of Taiwan stock market by four different phases. The result showed that the return rates of all periods in the four phases have appropriate ARIMA models. This result demonstrated that Taiwan stock market does not fit the weak form of EMH which assumed that analyzing historical information of stock prices is useless. |
