| 中文摘要:权证作为一种金融衍生工具，其到期必将对标的证券的价格与流动性产生重要影响。文章采用事件研究法分别就价内权证与价外权证到期对标的证券的影响进行研究。实证结果表明，在中国资本市场上权证到期对标的证券的影响具有一定特殊性，其中价内权证与价外权证到期前均对标的证券价格产生正效应，到期日后产生负效应；价内权证到期日后风险增加，流动性增强，价外权证则相反。 |

| A Study on the Call Warrants Expiration’s Impact on the Underlying Securities |
|
|
| Abstract:As a financial derivative instrument, the expiration of the warrants will have a significant impact on the price and liquidity of the underlying securities. In this paper, the impacts the call warrants have (both in the money and out of the money) on the underlying securities are explored using the method of event study. The empirical results demonstrate that the expiration of the warrants has some particular influence on the underlying securities in China’s capital market. Specifically, before the expiration date, both in the money warrants and out of the money warrants will have a positive impact on the underlying securities’ price, while after the expiration date, the impact turns negative. In addition, the risk and liquidity of in the money warrants increase after the expiration date, and vice versa for the out of the money warrants. |
