本研究分別利用傳統 OLS、誤差修正模型以及 Bivariate GARCH 模型研究以摩根台股指數期貨規避台灣股價指數的避險效果，現貨部分除了摩根台股指數現貨之外，亦考慮了台灣加權股價指數，目的在於瞭解摩根指數期貨的避險效果，並提出未來台灣加權股價指數上市後一套研究指數期約避險績效的研究架構。 本研究實證結果發現： (1)將台灣加權股價指數、摩根台股指數現貨以及摩根台股指數期貨的每日收盤價取對數值，並且依照避險期間分為三種情況，利用 ADF(Augmented Dicky and Fuller)進行單根檢定，結果顯示三個時間數列皆非定態(stationary)。 (2)時間數列取一階差分之後，視為指數的報酬率，同樣利用 ADF 進行單根檢定，結果顯示三個時間數列呈現定態(stationary)，亦即時間列服從 I (1)。此時，報酬的迴歸式存在具有實質意義。進行供整合檢定之結果顯示，無論是台灣加權指數與摩根台股指數期貨市場間，或是摩根台股指數之現貨與期貨市場間存在長期穩定之均衡關係。因此欲研究現貨與期貨市場的避險比率，應考慮誤差修正項。 (3)在加權股價指數與摩根指數期貨間避險效果方面： 1.在樣本內實證中，傳統 OLS 除了在避險期間為每日的情況之外，所造成投資組合變異數降低幅度較大，有較好的樣本內避險效果表現。 2.在樣本外實證中，傳統 OLS 無論在何避險期間，所造成投資組合變異數降低幅度較小，其避險效果皆較差。 3.避險誤差均方根比較方面，傳統 OLS 表現較差。 (4)在摩根台股指數現貨與摩根指數期貨間避險效果方面 1.在樣本內實證中，傳統 OLS 在各避險期間，所造成投資組合變異數降低幅度較大，有較好的樣本內避險效果表現。 2.在樣本內實證中，傳統 OLS 無論在何避險期間，其避險效果差皆較差。 3.避險誤差均方根比較方面，同樣以傳統 OLS 表現較差。 / Investors of Taiwan Stock Market have been long lack of hedging tools. SIMEX has provided a new merchant, MSCI Taiwan Index Future on January 9,1997. In addition, Taiwan Futures Exchange is going to run on July, 1998. Though investors are still not familiar with the new derivatives. Futures will be the new markets in Taiwan and it is the right time for us to analyze it. This research use different econometrics methods to check if it is a good hedge tool for the investors. The results are as followed. 1.The time series of MSCI Taiwan Index futures, MSCI Index Spots and Taiwan Weighted Index are not stationary. They are integrated of order 1. 2.There exist cointegrations between MSCI Taiwan Index futures and MSCI Index Spots, in addition to MSCI Taiwan Index futures and Taiwan Weighted Index. 3.OLS Regression, Error Correction Model and Bivariate GARCH Model are applied to find the optimal hedge retio. Among them, the hedge ratios of Bivariate GARCH Model are dynamic while the other two are constant. 4.According to the in-sample hedging effects results, the OLS are outstanding. The low variance of hedging portfolios and the reduction percentage compared to the no-hedged portfolios prove that. 5.Investors may care more about the out-sample results. From the table we know that Error Correction Model and Bivariate GARCH Model perform better than OLS, especially when the time period is longer. 6.When we check the RMSE, we get the same conclusion that OLS is the worst one among the three methods.

本文係利用高頻資料研究股票指數期貨的到期日效應，考量到中國的衍生性商品起步甚晚，相關研究不如台灣來的多，因此選取中國的滬深300股指期貨市場作為本研究的主題，希望能夠為後續有興趣的研究者提供參考。但是因為中國市場的資料取得不易，本文所使用的樣本資料只為期兩年，選取2010年4月16日到2012年4月20日的滬深300股指期貨的1分鐘高頻數據作為原始數據。 本文目的在於研究滬深300股指期貨經由考慮成交量、價格反轉以及波動度的到期日效應，實證結果發現在期貨到期日當天與隔一天的某些交易時段明顯存在著型0、型I與型II價格反轉，成交量檢驗指出，到期日成交量明顯大於非到期日成交量，波動度異常檢驗顯示，到期日收盤前五分鐘的波動度有異常放大的現象。本文的實證結果部分，利用模擬投資策略去檢驗價格反轉在經濟上是否有意義，發現價格反轉不只是在統計上顯著，同樣也是具有經濟意義的，但是把資料依據時間區分為前後兩部分並做檢驗之後也發現，這種經濟意義會隨著時間而呈現遞減的狀態。 / The central idea of this thesis is studying expiration effects of stock index futures. As we know, China stock index futures market, which is also known as CSI 300 Index futures market, is experiencing its early stage with fewer related studies comparing to Taiwan stock futures market. In order to provide research references for succeeding researchers interested in CSI 300 Index futures market. However, having difficulties collecting high frequency market data from CSI 300 Index futures market, we use only two years data from the beginning of CSI 300 Index futures market. The main purpose of this thesis is to study the expiration effect of CSI 300 Index futures by from three aspects, price reversals, volume effects and abnormal return volatility. The empirical results shows that type 0, type I and type II existed in several trading hours in both the expiration day and the next trading day. Second, it indicated that the trading volume in expiration days is significantly larger than in non-expiration days. Third, the empirical result also pointed out that magnified return volatilities existing in five minutes before market closes on the expiration day. Moreover, we used simulated investment strategies as analysis tools and found that price-reversal effect is significant on economical basis. However, we discovered that the level of these effects is declining gradually from the beginning to the end of data period.

本篇探討在2010年4月16日滬深300股指期貨正式上市到2012年9月18日止的連續近月每日收盤日資料，進行區域內金融期貨市場連動關係的研究，試圖發現兩岸三地之股價指數期貨市場在亞太地區的金融主導地位，以作為國內外投資者在區域內的投資決策參考。 實證結果顯示，從共整合及向量誤差修正模型檢定發現，兩岸三地股指期貨具有長期均衡及短期的互動關係，因此可以視此三地為單一區域市場。在Granger因果檢定上，台股指數期貨雖無法預測恆生指數期貨，但仍明顯領先滬深300股指期貨且程度大於恆生指數期貨，或可推測兩岸因ECFA的簽訂使實體經濟的關聯性更為緊密，至於恆生指數期貨大多以金融、地產股為其主要成分，與大陸主要以實體經濟為主的金融市場，其Granger預測滬深300股指期貨的能力因此相對較弱。另由衝擊反應檢定得知恆生指數期貨為一獨立的市場，不受台灣及大陸指數期貨市場衝擊的影響；滬深300指數期貨因大陸金融市場逐漸開放，也會受到香港及台灣金融期貨市場之衝擊而產生影響；至於台股指數期貨則在兩岸三地，最易受到其他市場影響。最後由預測變異數分解檢定發現，台股指數期貨及滬深300股指期貨的波動皆易受到恆生股價指數期貨變異的影響，而恆生指數期貨在兩岸三地間之解釋能力最強，於兩岸三地間具金融主導地位。至於台股指數期貨對大陸金融期貨的影響也有突出的表現，因此若政府有心推展亞太金融中心之營運，勢必得加強區域間整合的力度，提出有利吸引外資之最政策，以增加台灣股市於國際間之競爭力。 / This study conducts analysis of regional linkage between financial futures market by examining consecutive daily closing information from April 16, 2010 (the official list date of CSI 300 index futures) to September 18, 2012. This study tries to find the financial dominance of these index futures market in the Asia Pacific region and hopefully it may be used as an investment decision reference for domestic and foreign investors. The empirical results show that from the total integration and vector error correction model tests and three places all indicate long-run equilibrium stock index futures and short-term interaction. Therefore, these three places can be viewed as a single regional market. In the Granger causality test on the TAIEX futures and Hang Seng Index futures, in spite of TAIEX futures can’t predict Hang Seng Index futures, it is significantly ahead of the CSI 300 index futures. TAIEX futures on the CSI 300 index futures even more impact than the Hang Seng Index Futures. It can explain that the ECFA has been signed and results show closely-related economy. Since the Hang Seng Index futures are mainly from financial and real estate stocks while the mainland-based financial market is mainly from the real economy, Granger predicts ability of CSI 300 index futures is relatively weak. Another test on the impulse response shows that (1) Hang Seng Index Futures is an independent market and is not affected by shocks from Taiwan and the mainland index futures markets, (2) CSI 300 index futures is affected by shocks from Hong Kong and Taiwan because of the gradually open financial markets, and (3) TAIEX futures can be seen as a potential Taiwanese dish economy because it is most vulnerable to other market influences among the three places. To sum up, the forecast variance decomposition tests show that TAIEX futures and the CSI 300 stock index futures are vulnerable to fluctuations in the Hang Seng index futures. In order words, the Hang Seng Index futures have the strongest explanatory power among the three places and shows financial dominance. The TAIEX futures also show its significant impact on the mainland China financial futures index. If the Government decides to promote the operation of the Asia-Pacific financial center and to increase competitiveness of Taiwan stock market, it will inevitably have to strengthen inter-regional integration efforts and make the most favorable policies to attract foreign investment.
