Abstract: 先前學者在選擇權隱含貝塔係數的研究中主要是針對美國的選擇權市場,在本研究中,我們將針對台灣的市場進行研究,然而,由於台灣的個股選擇權的交易量非常小,因此我們以權證市場代替之,並調整先前學者所使用計算選擇權隱含貝塔係數的方法以合乎權證市場的特性。一檔權證的存續期間約半年左右,我們篩選出連續兩年〈2011年3月至2013年2月〉皆有被券商發權證的公司,將這些公司依權證隱含貝塔係數之大小分成三組,分別觀察三組以及以買高貝塔賣低貝塔投資組合策略在未來一週至未來四週之報酬的表現。此外,我們研究未來第一週至未來第四週的報酬與權證隱含貝塔和其他控制變數的關係,以得知權證隱含貝塔係數是否可以為未來的股票報酬提供資訊。
Previous studies of option-implied beta focused on US’s option market. Since the trading volume of stock option in Taiwan’s option market is greatly small, we use warrant data instead and apply in an adjusted way to compute warrant-implied beta to generate four warrant-implied betas in a week period rather than a single implied-beta. Firms issued continuous two-year warrants were sorted into three groups based on implied beta. We conducted long-short strategies to examine the performance of stock returns in different periods with different implied-beta. In addition, we investigated the relationship between different-period future stock returns and control variables to verify the effects of warrant-implied beta to future stock return.
