Abstract

This paper proposes an efficient portfolio selection methodology for the listed construction corporations in KOSPI and KOSDAQ. For the construction industrial sector classified by KRX(Korea Exchange), the proposed method carries out an efficiency analysis using DEA (Data envelopment analysis) approach and for the efficient corporations filtered by DEA, construct portfolio using Markowitz's Model. In order to show the effectiveness of the proposed method, we constructed annually portfolios for 5 years (2007-2011) out of 53 listed corporations in KOSPI and KOSDAQ, and proved that our portfolios are superior to benchmark portfolios in terms of rate of returns.

본 연구에서는 KOSPI와 KOSDAQ에 상장된 건설 기업을 대상으로 효율적인 포트폴리오를 구성방안을 제시한다. 이를 위해 한국거래소(KRX)에서 구분하는 건설 업종을 DEA(Data Envelopment Analysis) 기법을 이용하여 기업효율성 분석을 실시하고 효율성이 우수한 기업들을 대상으로 마코위츠 모형을 통해 포트폴리오를 구성한다. 본 연구에서 제안한 포트폴리오 구성 방안의 성능 실험을 위해 KOSPI와 KOSDAQ에 상장된 53개의 기업의 주식을 대상으로 5년 (2007~2011) 동안 매해 포트폴리오를 구성하였고 각각의 포트폴리오 수익률을 경영 효율성을 고려하지 않고 구성한 포트폴리오 및 벤치마크 수익률과 비교 분석을 통해 그 우수성을 입증하였다.
