中文摘要 | 本研究目的在於了解鴻海股票日收盤價與的報酬率最佳模式預測的準確性。研究方法爲利用延伸樣本自我相關函數(extended sample autocorrelation function,簡稱ESACF)提出原始模式,研究資料取自鴻海股票1999年1月1日至2006年4月30日,經由配適度及殘差檢定選取出最佳模式,最後進行模式的預測分析。研究結果發現報酬率的最佳模式ARIMA(0,0,4),而日收盤價最佳模式爲ARIMA(0,1,4),兩模式所預測出來的值雖與實際值有些許差距,但皆落於95%的信賴區間之內。 |
英文摘要 | The aim of this research is to probe the best ARIMA model for the daily close prices and return rates of the Foxconn stock, and to forecast the accuracy of prediction. We applied Extended Sample Autocorrelation Function to determine the parameters of ARIMA model. The data of this research came from the Foxconn stock price during January 1, 1999-April 30, 2006. We employed the goodness of fit and residual error test to selects the best model. Finally, we performed the forecast and the analysis of ARIMA model. Our results showed that the best model for daily close prices is ARIMA (0, 1, 4). Moreover, we found that the best model for return rates is ARIMA (0, 0, 4). Although the forecast has a little difference between predicted values and the actual values for both models, all fall into 95% confidence interval. |
