摘要 本研究採用分量迴歸模型(Quantile Regression, QR)去探討IBM在一分鐘資料下報酬率與成交量和美元指數主要匯率(歐元兌美元、英鎊兌美元、日幣兌美元、加拿大幣兌美元)去探討他們之間的相互關係並以2008年金融危機作為分界點,實證結果發現,在一分鐘資料下,分量迴歸更可以準確顯示出IBM價量之間的關係。而IBM報酬率、成交量與匯率報酬率經由單根檢定發現皆屬於定態,實證結果發現IBM價量有明顯的關聯性,右尾呈現價量齊揚的關係,左尾呈現價量背離的關係,但在2008年金融危機發生時皆造成價量背離的結果,並影響金融危機的往後幾年價量齊揚的關係增加但效果較之前不明顯。
ABSTRACT The study take account Quantile Regression(QR) to discuss the close price and volume of IBM corporate and the main exchange rate of US dollar index, EUR/USD, GBP/USD, USD/JPY and USD/CAD in one minute data to understand the relation between them and to understand the influence of the gap of 2008. In the result, when in one minute data, QR can indicate more the relation of the price and volume of IBM corporate, but exchange rate is lesser. Due to the unrobustness of the close price of exchange rate and the close price of IBM corporate. In the result, I find that the relation of close price and volume has interaction, and the right-tail has a positive effect, left-tail has a reverse effect. Furthermore, the influence of 2008 has a reverse effect in the mean time and it has positive effect on the years after 2008.
