發行認購權證對標的股票股價影響之實證研究

張啓容 Unknown Date (has links)
認購權證屬於衍生性金融商品,其發行與存續期間之價格必然與標的股票價格產生互動關係,故本文探討認購權證的發行期與發行後對標的股票股價的影響。 本研究首先檢定發行認購權證事件,對標的股票股價是否會產生正的異常報酬,然後發行認購權證事件,標的股票股價的波動性是否降低,最後再用Amihud和Mendelson的模型解釋股價的波動性變化的來源。 實證結果顯示,發行認購權證事件未對標的股票價產生正的異常報酬;而發行認購權證後,標的股票股價的波動性降低,而股價對新資訊的反應速度加速以及標的股票的股票的流動性造成的波動性會降低。
