【摘要】:股指期貨與現貨具有非常緊密的聯系,探討股指期貨和現貨在時間上的領先-滯后關系及波動的相關性具有非常重大的意義。滬深300股指期貨是我國目前唯一的股指期貨,但根據中國金融期貨交易所的規(guī)定,機構投資者在股指期貨市場上被限定為只能進行套期保值交易,本文就是在此背景之下采用實證分析的方法研究了滬深300股指期貨和滬深300指數在時間上和價格波動上的互動關系。文中的數據選用了2013年2月4日至2013年3月25日期間滬深300股指期貨和現貨的15分鐘收盤價。文章采用了以下技術思路:首先,通過平穩(wěn)性檢驗、Johansen協(xié)整檢驗確定兩者之間長期和短期內均衡的關系,然后,建立VAR模型和向量誤差修正模型,并根據Granger因果檢驗探討滬深300股指期貨和股指現貨之間的領先-滯后關系,最后,利用脈沖響應及方差分解的方法觀察滬深300股指期貨和現貨在波動上的相關性。 研究結果表明,在長期內,滬深300股指期貨和滬深300指數之間是均衡的,且互為Granger因果關系,但在短期內,兩者都是非平穩(wěn)的,股指期貨領先于股指現貨。研究進一步表明,股指期貨市場對信息的反應更為迅速,具有更好的信息效率。雖然兩者的波動和走勢主要由自身決定,,但是期貨對現貨市場的影響大于現貨對期貨的影響。
[Abstract]:Stock index futures have a very close relationship with spot. It is of great significance to discuss the leading-lag relationship and fluctuation correlation between stock index futures and spot in time. Shanghai and Shenzhen 300 stock index futures are the only stock index futures in China at present. However, according to the regulations of the China Financial Futures Exchange, institutional investors are restricted to hedging transactions in the stock index futures market. Under this background, this paper studies the interaction between CSI 300 stock index futures and CSI 300 index in time and price fluctuation by using the method of empirical analysis. The data selected from February 4 2013 to March 25 2013 CSI 300 stock index futures and spot closing price 15 minutes. In this paper, the following technical ideas are adopted: firstly, the equilibrium relationship between the two is determined by the Johansen cointegration test, and then the VAR model and the vector error correction model are established. Based on the Granger causality test, the leading-lag relationship between Shanghai and Shenzhen 300 stock index futures and stock index spot is discussed. Finally, the correlation between Shanghai and Shenzhen 300 stock index futures and spot is observed by the method of impulse response and variance decomposition. The results show that in the long run, the Shanghai and Shenzhen 300 stock index futures and the Shanghai and Shenzhen 300 index are balanced, and each other is Granger causality, but in the short term, both of them are non-stable, and stock index futures are ahead of the spot stock index. The research further shows that the stock index futures market responds to information more quickly and has better information efficiency. Although the volatility and trend of both are mainly determined by themselves, the impact of futures on the spot market is greater than the impact of spot on futures.
