摘要


本研究運用Koenker 與 Bassett(1978)所提出分量迴歸(Quantile Regression)模型探討融資餘額、融券餘額以及外資買賣超對於台灣八大類股(水泥窯製、食品飲料、重機重電、紡織纖維、塑膠石化、造紙工業、營造建材、金融保險)股價指數的影響,再進一步探討此三變數在股價漲停、跌停時影響的差異性。本文以日資料進行實證分析,研究期間為2006/01/02至2007/12/31。 本研究結論如下: 1.融資餘額對八大類股在股價漲停與跌停時幾乎是正向顯著,只有在重機重電類、金融保險類股除外,大部分的類股中,漲停股價的影響皆程度大於跌停股價,亦即在漲停股價時融資餘額較容易刺激股價的成長。 2.融券餘額對股價影響多為正向顯著,不同的是水泥窯製類股是屬於負向顯著。對股價漲停、跌停影響也不對稱,且依各類股不同融券餘額對漲停、跌停股價影響程度也不同。 3.外資買賣超此變數對於八大類股為正向影響。在水泥窯製類股停、食品飲料及紡織纖維的跌停是負向但不顯著,而在水泥窯製類股在漲跌停具有不對稱的影響效果,其餘類股股價在漲停和跌停時,皆屬對稱影響。 4.在各類股中,利用最小平方法分別對變數在股價漲停或跌停時係數估計,將有明顯的高估或低估情形發生,無法完整呈現變數對股價的影響以及無法正確估計股價在漲跌幅限制的效果。 本研究之實證結果,可提供投資人了解在各類股中各變數分別對漲停、跌停股價影響的差異,將有助於投資人在面臨各類股股價波動的情形下選擇投資決策。

並列摘要


The object of this study is to apply quantile regression method (QR) to examine the effects of margin purchase /sales, and net foreign buying/selling on Taiwan’s stock prices, which are cement, food, electronic and electric machinery, textile, plastic and chemical, paper, construction, and financial and insurance. The data employed in this study is from January 2, 2006 through December 31, 2007. The empirical results show that purchase /sales, and net foreign buying/selling have different impacts on upper price limit and lower price limit among various categories. Margin purchase has significantly positive impacts on most of categories in the case of either upper or lower price limit. The influences on upper limit price and on lower limit price are not symmetrical. Margin sales have positive significantly impacts on both price limits for most of industrial categories such as cement, food, electronic and electric machinery, financial and insurance. The impacts of net foreign buying are positive but not significant, which indicates the influence of foreign institute investors are overlooked by general investors. Finally, this study compares the estimation results of QR with those by applying ordinary least square method (OLS). It shows that the estimated coefficients by OLS could overestimate or underestimate the impacts of margin purchase /sales, and net foreign buying/selling on upper price limit or lower price limit. The findings of this study are expected to provide insights of stock prices for individual investor in Taiwan.
