본 논문은 우리나라 옵션시장의 변동성요인이 주식투자자들의 선택에 영향을 미치고 있는지를 검토한다. 본 논문은 옵션상품이 경제 내에서 비여분자산 (nonredundant securities) 으로서의 기능을 담당하고 있다는 최근 연구결과에 따라 변동성 요인을 자산가격결정 모형의 조건부 변수로 도입한다. 본 논문이 사용하는 변동성요인은 KOSPI200 지수에 대한 제로베타 등가격 스트레들 수익률이다. 동 수익률 변수를 조건부변수로 사용한 결과 주식시장에서의 자산가격결정모형의 가격결정력에 상당한 개선이 나타나는 것이 확인되었다. 따라서 주식 투자자들이 주식수익률에 대한 예상을 형성하는 경우 스트레들 수익률을 도구변수로 활용하고 있다고 해석할 수 있다. 한편 변동성요인과 시장수익률을 설명변수로 설정하고 각각의 기업그룹별 수익률에 대한 시계열회귀분석을 실시한 결과, 우리나라 주식시장에서는 소형 가치주보다는 대형 성장주그룹에서 변동성 요인에 대한 계수 값이 크게 나타나고 있어 미국 주식시장에 대한 연구결과와 유사한 결과를 나타내었다. 이는 우리나라 주식시장에서도 투자자들이 경제전체의 변동성에 대한 헤지수단으로 대형 성장주를 소형 가치주에 비해 선호하고 있음을 나타낸다. 이와 같은 발견은 옵션시장의 변동성 요인이 주식투자 포트폴리오 구성과 위험관리 및 헤지전략의 구성에 중요한 의미를 갖고 있음을 의미한다.

변동성요인이 자산가격에 미치는 영향에 관한 연구

We investigate if the straddle return on the KOSPI 200 index can be a conditional factor in understanding the behavior of investors in Korean stock market. In recent years, several studies showed that options are non-redundant securities in the economy. As a result, returns of options should appear as conditional factors in explaining the cross section of stock returns. In Hansen-Jagannathan distance test, we found that the performance of the conditional CAPM and conditional Fama-French 3 factor model improved when we used zero-beta at-the-money straddle returns of the KOSPI 200 index as a conditional factor. But the explanatory power of option volatility risk factor shows different patterns for different classes of stocks. In a regression, the coefficient of determination of large and value stock is larger than small and growth stocks of our Fama-French 16 test portfolios. These finding suggest several important implications for investment and risk management in Korean security market. 본 논문은 우리나라 옵션시장의 변동성요인이 주식투자자들의 선택에 영향을 미치고 있는지를 검토한다. 본 논문은 옵션상품이 경제 내에서 비여분자산(nonredundant securities) 기능을 담당하고 있다는 최근 연구결과에 따라 변동성 요인을 자산가격결정 모형의 조건부 변수로 도입한다. 본 논문이 사용하는 변동성요인은 KOSPI 200 지수에 대한 제로베타 등가격 스트래들 수익률이다. 동 수익률 변수를 조건부 변수로 사용한 결과 주식시장에서의 자산가격결정모형의 가격결정력에 상당한 개선이 나타나는 것이 확인되었다. 따라서 주식 투자자들이 주식수익률에 대한 예상을 형성하는 경우 스트래들 수익률을 도구변수로 활용하고 있다고 해석할 수 있다. 한편 변동성 요인과 시장수익률을 설명변수로 설정하고 각각의 기업그룹별 수익률에 대한 회귀분석을 실시한 결과, 우리나라 주식시장에서는 변동성 요인의 계수추정치가 통계적으로 유의한 양의 값을 나타내지 않았다. 이는 우리나라 옵션시장에서 대부분의 투자자들이 헤지목적보다는 투기목적으로 참여한다는데 기인한다. 이 결과를 종합하면, 우리나라 옵션시장의 변동성 요인은 자산시장에 동시적 영향을 주기보다는 시차를 두고 영향을 미친다고 평가할 수 있겠다.
