本研究探討新加坡摩根台股指數現貨與期貨價格之領先-落後關係。研究期間從 1998年 3 月 1 日至 3 月 18 日，選取現貨指數與最近月份（３月）之期貨契約每 5 分鐘成交價格，總共有 506 比觀察值。在分別以 Engle-Granger ( 1987 )的兩階段估計法與 Johansen ( 1988 )的最大概似法做共整合檢定之後，發現期貨與現貨價存在「共整合現象」，因此以 Granger ( 1986 ) 所建議的誤差修正模型檢定期貨與現貨價格的領先-落後關係。
實證結果如下：
1.在檢定期貨與現貨價格的領先-落後關係上，以兩種共整合檢定方法為基礎得出的誤差修正模型，獲得一致的結論，也就是發現期貨價格領先現貨價格，「 Granger 因果關係」亦顯示，兩數列有單方向「因果」關係，表示摩根台股指數期貨價格是現貨指數的「因」，而現貨指數則不是期貨價格之「因」。
2.在期貨價格領先現貨價格的時間方面，期貨價格大約領先現貨價格達 15 分鐘前的期貨價格資訊對當期限貨價格有影響力。
3.上述「期貨價格領先現貨價格」的結論與大部份學者研究結論相同，但與研究同樣商品的賴瑞芬 ( 1997 ) 不同，推論主因應為 SIMEX 摩根台股指數期貨支成量擴增，交易越來越頻繁，使期貨市場日漸成熟之故。 / This study investigates the lead-lag relationship of SIMEX MSCI Taiwan Index futures and spot prices. The sample period is from 1998/3/1 to 1998/3/8. From the two cointegration tests of Engle-Granger's (1987)“Two Step Estimation” and Johansen's(1988) “Maximum Likelihood Method”, I find a “cointegration ”relationship between spot and futures prices. And then, I use the “error correction model”to test the lead-lag relationship.
The empirical results indicate:
1.The lead-lag relationship estimates suggest that two error correction models from different cointegration test have the same conclusion:futures prices lead spot prices. From Granger's causality tests, there is an unidirectional causal relationship: futures prices Granger-cause spot price.
2.Futures prices lead spot prices about 15 minutes. In other words, 15 minute-before futures prices have an influence on present spot prices.
3.The conclusion of lead-lag relationship between spot and futures prices corresponds to most empirical results, but conflicts with Lai(1997) who investigates the same futures contract. I think the “volume”is the dominant factor.
