Abstract
본 논문은 KOSPI 200 지수옵션 시장을 대상으로 하여, 파생상품의 가격변화는 기초가 되는 자산의 가격변화에만 영향을 받는가 및 각 월별 옵션 만기시 원월물에서 근월물로 바뀌는 옵션의 이월현상 효과를 분석하였다. 분석을 위해 1999년부터 2001년까지의 KOSPI 200 지수옵션의 패널데이터(Panel data)를 사용하였으며 다음과 같은 결과를 얻었다: 첫째, 만기일을 포함한 주 단위인 월~다음월, 수~금 기간동안의 콜옵션에서 우리가 일반적으로 예상했던 기초자산의 가격변화에만 파생상품의 가격은 영향을 받는 다는 이론에 배치되는 특이요인(Stylized factor)이 발견되었다. 둘째, 기간을 세분화하여 분석하였을 때, 콜옵션은 수~목 기간에서는 가격상승 현상이 나타났으며 목~금 기간에는 가격하락 현상이 나타났다. 반대로 풋옵션은 수~목 기간에는 가격하락 현상이 나타났으며 목~금 기간에는 가격상승 현상이 나타났다. 이러한 현상이 만기 이월현상 때 나타난다는 것이 처음으로 밝혀졌고 그 방향성이 나타난 점이 특이하다고 판단된다. 셋째, 위와 같은 결과를 바탕으로 투자전략을 수립할 때, 시장거래자중 콜옵션을 매수하려고 하는 투자자는 Rollover 이후에 하는 것이 좋으며, 콜옵션을 매도하려 할 경우 Rollover가 포함된 주 초반에 하는 것이 좋은 것으로 나타났다.
Alternative Abstract
The object of this thesis was the KOSPI 200 Index Options Market and the research was done on two subjects: 1) Whether the price changes of derivatives were only influenced by the price changes of the basic assets. 2) Analysis on the option rollover effects from near month contracts to far month contracts at the time of each monthly option maturity. For this analysis, panel data of KOSPI 200 Index Option Prices from year 1999 to year 2001 were used, and following results were obtained. First- Stylized factor was found and that was adverse to the generally estimated theory which in weekly call option, such as, from Monday to next Monday which included the maturity date, and on the period from Wednesday to Friday, the prices of derivatives were only affected by the price changes of the basic assets. Second- Analysis was also done when period was subdivided. Price ascending phenomenon of call option was noticed during Wednesday to Thursday and price descending phenomenon of call option was noticed during Thursday to Friday. Adversely, price descending phenomenon of put option was noticed during Wednesday to Thursday and price ascending phenomenon of put option was noticed during Thursday to Friday. It was discovered for the first time that these phenomena were noticed near the maturity date. It was concluded that this fact showed unique direction. Third-Based upon the above results, we can make better investment strategy for option traders. For those investors who want to purchase call option, it is better to do so after rollover. And for those investors who want to sell call option, it is better to do so on the beginning of the week which includes rollover.
