漲跌幅限制變動對於磁吸效應的影響

The Influence of Changing Price Limits on the Magnet Effect

指導教授 : 張雅凱 陳佑倫

摘要


本研究為了檢測在放寬漲跌幅限制後磁吸效應會有何差異,從台灣證券交易所與台灣經濟新報取得相關資料,利用台灣中型100指數成份股的股票,並且參考Hsieh, Kim and Yang (2009) 的模型,來檢測改制前與改制後磁吸效應的差異。 研究結果發現,當股票在上漲的時候,改制前與改制後的磁吸效應開始發生的位置皆在離漲停板4個升降單位,磁吸效應並沒有延遲或提早發生;而股票在下跌的時候,改制前的磁吸效應在離跌停板3個升降單位的位置開始發生,但是改制後的磁吸效應卻不明顯,所以下跌模型結論與上漲模型並不一致。

並列摘要


The purpose of this study is to exam the different of magnet effect after relaxing the price limits. We get relevant data from Taiwan Stock Exchange and Taiwan Economic Journal. To detect the difference of magnet effect before and after system reform, we used the stock of Taiwan Mid-Cap 100 Index as a sample and referred to the model of Hsieh, Kim and Yang (2009). The results show that when the stock is going up, the position of the magnet effect started before and after system reform is within four ticks of the upper price limits, there is no delay or early occurrence of magnet effect. When the stock is going down, the magnet effect before the system reform is within three ticks of the lower price limits. However the magnet effect after the system reform is not obvious. The outcome of down model is inconsistent with the up model.
