Abstract

This paper is to understand investment's efficiency and performance of commercial real estate assets diversified by use and district. To do so, this paper divides two different commercial real estate markets(office build market and retail real estate market) in Seoul city by district into "GBD(Gangnam Business District), YBD(Yeouido Business District), and CBD(Central Business District)" and "GBD(Gangnam Business District), SBD(Shinchon Business District), and CBD(Central Business District)" respectively, configures these districts each other to structure portfolios as its portion varies based on Markowitz's Mean-Variance principle, and looks at risk-return relationship of portfolios to find out efficiency, performance, and optimal investment chosen based upon Sharpe's Performance Index. As a result, the portfolio configured by "10 to 30% of office building asset at CBD" and "70 to 90% of retail real estate asset at CBD" is shown to be the most optimal, suggesting the highest quarterly Sharpe's performance index of 2.7118~2.7776 with quarterly rate of return of 1.826%~1.838% and quarterly standard deviation of 0.573~0.589. Furthermore, it is obvious that diversified portfolio configured by use(office-retail) shows better investment performance than that by district with same type of asset(office-office or retail-retail). Finally, results driven from this research will play an important role to stimulate real estate and construction markets through enlarging ideas as to diversified investment by use and district on real estate indirect investment products.

본 연구는 서울에 위치한 오피스 빌딩 및 소매용 부동산 자산 간 권역별 포트폴리오의 구성을 통해 서로 다른 용도의 상업용 부동산 간의 분산 투자 시, 포트폴리오의 위험-수익률 관계를 파악함으로써 투자의 효율성과 성과를 알아보는 것을 목적으로 한다. 이를 위해 Markowitz의 평균-분산모델을 토대로 서울지역의 오피스 빌딩 자산과 소매용 부동산 자산을 권역별로 분류하여 이들 간의 포트폴리오를 구성한 후, 포트폴리오의 투자성과, 효율성, 그리고 Sharpe 지수에 기반한 최적의 포트폴리오를 확인하였다. 구체적으로, 서울의 3대 오피스 빌딩 시장인 강남권, 여의도 마포권, 그리고 도심권과 소매용 부동산의 3대 시장인 강남권, 신촌 마포권, 그리고 도심권에 대하여, 부동산 자산의 용도와 권역에 따라 투자비율을 달리해가며 포트폴리오를 구성하였다. 분석결과, 도심권 오피스 권역의 자산비중 10~30%와 도심권 소매용 부동산 권역의 자산 비중 70~90%로 구성한 포트폴리오가 가장 높은 분기별 Sharpe 지수인 2.7118~2.7776을 제시해 최적의 자산구성임을 알 수 있었으며 이때의 분기별 수익률은 1.826%~1.838% 그리고 분기별 위험은 0.573~0.589였다. 또한 부동산 자산 간 권역별 포트폴리오의 구성 시, 서로 다른 용도를 지닌 자산간의 포트폴리오 구성에 의한 분산투자가 동일한 투자자산의 권역별 분산투자 보다 더 좋은 투자성과를 보여주는 것을 알 수 있었다. 마지막으로, 본 연구의 결과를 바탕으로 부동산간접투자시장에서도 지역 및 용도별 분산투자에 대한 이해의 폭을 넓혀 부동산 및 건설경기의 활성화에 도움이 되기를 기대한다.
