Abstract

This study aims to develop and analyze the performance of a selective option straddle strategy based on forecasted volatility to improve the weakness of typical straddle strategy solely based on negative volatility risk premium. The KOSPI 200 option volatility is forecasted by the SVM model combined with the asymmetric volatility spillover effect. The selective straddle strategy enters option position only when the volatility is forecasted downwardly or sideways. The SVM model is trained for 2008-2014 training period and applied for 2015-2018 testing period. The suggested model showed improved performance, that is, its profit becomes higher and risk becomes lower than the benchmark strategies, and consequently typical performance index, Sharpe Ratio, increases. The suggested model gives option traders guidelines as to when they enter option position.

본 연구의 목적은 음의 변동성위험프리미엄 특성에 기반한 전통적인 옵션 양매도전략의 문제점을 개선하기 위해, 변동성 예측을 이용한 양매도 포지션의 선택적 진입전략을 제안하고 그 투자 성과를 분석하고자 하였다. 선택적 진입전략은 비대칭적 변동성 전이효과와 SVM 모형을 결합하여 KOSPI 200 주가지수옵션시장의 장중 변동성이 하락이나 횡보로 예측되는 날만 양매도 포지션을 진입하는 옵션의 스트래들 매도전략이다. 2008년부터 2014년까지의 실험데이터에서 변동성의 최적 분류 모형을 찾아내고, 2015년부터 2018년까지의 검증데이터에 적용해 본 결과 제안모형이 비교모형보다 수익은 증가하고 투자 위험은 감소하는 우수한 결과를 보여주었다. 따라서 투자성과지표인 Sharpe Ratio가 증가하는 좋은 결과를 얻을 수 있었다. 제안 모형은 옵션 거래자들에게 언제 포지션을 진입하고 언제 진입하지 말아야 하는지에 대한 가이드라인을 제시하고 있다.
