摘要


本研究利用臺灣期貨交易所2010 年6 月18 日至2012 年10 月17 日的日資料, 共584 個交易日。先以現貨市場股票市值前八大公司為標的,再篩選其中有完整股 票期貨交易資料的公司,結果選定台積電、鴻海及聯發科三家公司作為研究對象, 以因果關係檢定、衝擊反應分析及變異數分解等方法檢定股票期貨與現貨之間的領 先落後因果關係,實證結果如下: 一、 因果關係檢定:台積電,鴻海及聯發科在股票期貨及現貨之間無因果關係。 二、 衝擊反應分析:台積電、鴻海及聯發科三家公司股票期貨及現貨在面對另一變 數的衝擊時,在前二期皆為較明顯的正向衝擊反應,之後呈現小幅正負向上下 波動的影響,台積電的影響時間會延續八期,鴻海持續小幅波動,聯發科則延 續六至七期。 三、 變異數分解:台積電、鴻海及聯發科三家公司實證結果皆顯示股票期貨的變異 對現貨的預測誤差變異有較高影響力,即股票期貨對現貨的預測能力較高。

This study collects and analyzes 584 trading historical data from Taiwan Futures Exchange, since 18 June, 2010 to 17, October, 2012. Top eight companies by market value in Taiwan are firstly chosen as the candidates of this research. Three of them, TSMC, Hon Hai Group, and MediaTek, are then screened as our research targets according to the completeness on trading historic of stock futures. This research uses the causality test, impulse response analysis and variance decomposition to test the causality relationship between single stock futures and underlying stocks. The empirical findings are summarized as follows: 1. Causality test: No causal relationship between the spot price and stock futures for TSMC, Hon Hai and MediaTek. 2. Impulse response analysis: The stock futures of TSMC, Hon Hai, and MediaTek show more significant positive impacts in former two periods, then show slight volatility impacts. The impact of TSMC will continue within eight periods and MediaTek is six to seven periods. 3. Variance decomposition: The stock futures of TSMC, Hon Hai, and MediaTek have more influence and predictive ability than spot prices.
