    摘要: 認購權證已在台灣發行與交易已接近七年的歷史，提供了更多套利、投機與避險交易的機會給市場參與者，也同時增加資本市場之完整性。而由於認購權證提供持有者在一段期間內依照特定價格購買特定數量標的股票之權利，投資人可以根據其意願與看法於到期日前來決定是否進行履約。而權證投資人購買權證之權利金即是包含內含價值與投資人願意支付的時間價值兩部分。時間價值的多寡反應出投資人對於未來權證履約價格是否可以無限增加的看法。而在其他條件不變之下，距到期時間越久之權證的價值應是越高。不過，是否時間越接近到期日時，投資人對於時間價值的看法就會呈現單純線性下降的狀態，還是另外有其他的資訊內涵會影響投資人對於價值的看法，即為本研究所欲探討之主題。
    本研究針對台灣市場中個股型認購權證不同時點之時間價值變化程度，與可能影響時間價值變化的因素進行分析，其研究結果如下：
    1.研究樣本並非完全符合越接近到期日時間價值減少的現象越明顯的狀態，顯示時間價值的變化隱含著會有其他之因素影響投資願意支付金額的多寡。且部分權證的確曾發生短期內時間價值大幅衰減的現象。
    2.權證之價內外程度、距到期日之遠近、相對交易量的多寡與標的股票是否為電子業，對時間價值減少均有顯著的影響。另外，距到期日之天數、權證相對成交量、標的股票所屬產業與市場是否處於多頭與否均顯著影響短期內發生時間價值大幅衰退之現象。
    3.本研究發現目前無法利用權證發行條件的差異，來判斷此權證是否會在存續期間當中發生時間價值急速衰退的現象。
    Warrants has been traded in Taiwan for seven years, and provides more opportunities for participants to arbitrage, hedge and speculate in capital market. Warrant gives holders the right to buy stocks at certain price during a period of time. The premium (price) to long warrants is contained intrinsic value and time value. Other things being equal, the longer the time to expiration day, the higher the value of warrants, since there is larger probability for investors to get more return. However, would any other terms expect time to expiration affect the variations of time value, or if we can find some variables could provide other content of information and result the change of time value. This is what the study focus on. Followings are the results of this study:
    1. There are not all thetas of warrants in this sample decreasing simply by the time to expiration. It seems to be other variables would cause the change of theta. Besides, some warrants had serious time-decay in a short period of time.
    2. Intrinsic value, time to expiration, trading volume, whether underlying stock in electronic industry or not and the market condition all have obvious effects on decrease of time value and serious time-decay.
    3. It is still impossible to use issue information to identify if this warrant will have time-decay in its life.
