類股指數領先大盤抑或是大盤領先類股指數?–簡單周期判定法則之應用 / Can Industry Index predict TAIEX, or vice versa?–The application of a simple dating technique

陳怡瑄 Unknown Date (has links)
本文引用Pagan and Sossounovb(2003)針對Bry and Boschan(1971)景氣循環周期判定法修改後的法則,判定大盤與類股指數的牛市、熊市周期。將判定的周期結果畫成圖表,藉由簡單的圖表分析將可明確得知大盤周期與類股周期領先與落後的關係,並應用計量模型估計,找尋能夠顯著預測大盤周期變動方向的類股,或是檢驗大盤周期是否能夠預測類股周期方向;反之亦然。並且比較圖表分析與計量模型估計結果是否一致。 圖表分析與向量自我迴歸模型的實證結果一致,八大類股中,營建、金融、機電、塑化等四類股周期能夠顯著預測大盤周期走勢,其中以塑化類股最具預測能力;而大盤周期皆無法精準預測類股周期走勢。而羅吉斯迴歸模型結果也發現,營建、金融、機電、塑化等四類股周期能夠增加大盤周期走勢的預測機率;同樣的,大盤周期無法影響類股周期走勢的預測機率。

台股情緒指標建構及與股市關係 / Construction of Sentiment Index and the Relationship between Sentiment Index and TAIEX Return

吳佩蓉, Wu, Pei Jung Unknown Date (has links)
本研究最主要的貢獻為建構一具台灣股市投資人情緒指數並檢測投資人情緒指標與台灣股市的關係。本研究以台灣股票市場為背景,研究期間為2001年1月至2010年12月。利用Baker, Wurgler and Yuan在2009年提出的方法以Volatility Premium, Number of IPOs, First Day Return of IPOs, Turnover Rate四個變數編製台灣股市投資人情緒指數,並探討台灣股市投資人情緒指數變動量與台股大盤報酬之間的領先落後關係。 實證結果發現,在較短的時間,如月資料,台股大盤報酬會影響下一期的台灣股市投資人情緒指數變動量,而在較長的時間,如季資料,台灣股市投資人情緒指數變動量會影響四期後的台股大盤報酬,即短期台灣股市投資人情緒指數變動量為大盤報酬之落後指標,長期則為大盤報酬之領先指標,短期原因為投資人情緒指數受大盤報酬影響,而易有追高殺低現象,長期雖投資人情緒領先大盤報酬的結果在統計上顯著,但經濟上並無顯著意義,另一方面,台股大盤報酬與台灣股市投資人情緒指數變動量間存在正相關,即不能以台灣股市投資人情緒指數變動量預測股市泡沫。 / The main contribution would be the construction of the sentiment index in Taiwan stock markets and examining the relationship between the variation of the sentiment index and Taiwan stock market returns. The background is Taiwan stock markets. The sample period is from January 2001 to December 2010. We use the method in Baker, Wurgler and Yuan (2009) to measure investors’ sentiment and explore the relationship between the variation of the sentiment index and Taiwan stock market returns. The empirical result reveals that in monthly data, Taiwan stock market returns is the leading indicator of the variation of investment sentiment. In a longer term, we mean the quarterly data in this paper, the situation changes. In quarterly data, the variation of the investment sentiment is the leading indicator of the Taiwan stock market returns. In addition, instead of a negative correlation between the stock market returns and our sentiment index, we prove that our sentiment index have a positive impact on stock market returns. Therefore, we could not use this sentiment index to forecast future economic bubbles.
