Abstract

The purpose of this paper is to see what the problem is and what the direction of the Investment of ELB is after this study has analyzed an achievable possibility for a suggested yield of ELB. It analyzes estimated yields from January in 2010 to June in 2016 for ELB Structures issued during 2015~2016. It carries correlation analysis and regression analysis between ELB yield and minimum guarantee yield, maximum stock price growth limit, participation rate. As the study result, a probability of achievement over 2% yield was below 20% as stock price growth had been inside maximum limit. An estimated average yield of ELB was 1.49% and it was lowed than 1.72% of Bank Deposit in 2015. So a realized yield was not satisfied the expected yield. As the correlation coefficient between ELB yield and minimum guarantee yield was 0.843, the correlation coefficient between ELB yield and maximum limit yield was 0.279, the correlation of minimum guarantee yield was high. The suggestion is that the a realized yield of ELB is lower than Bank Deposit interest and that the probability of stock growth inside maximum limit is low.

본 연구의 목적은 주가연계사채(ELB)의 제시수익률에 대해 달성가능 정도를 분석하여 ELB 문제점을 도출하고, ELB 투자방안에 대한 방향성을 제시하고자 한다. 연구방법은 2015~2016년에 발행된 ELB 구조를 2010년 1월부터 2016년 6월까지 추정수익률을 분석하며, 최소보장수익률, 최고한도율, 참여율과 실제수익률 간의 상관관계와 회귀분석을 실시한다. 분석결과는 주가상승률이 최고상승률 한도를 벗어나지 않아서 주가상승률에 의해서 은행금리수준보다 높은 2%이상의 수익률을 달성할 확률은 20%에도 미치지 못하며, ELB 상품의 평균추정수익률은 1.49%에 불과하여 은행의 2015년 수신금리인 1.72% 보다 낮아서 ELB의 실현가능수익률이 기대치에 미치지 못한다. 최소보장수익율과 ELB 수익률의 상관계수는 0.843, 최고한도수익율과 ELB 수익률의 상관계수는 0.279로 산출되어 ELB 수익률과 최소보장수익율 간에 상관관계는 매우 높다. 시사점은 ELB 실제수익률이 은행예금금리 보다 높지 않으며, 주가상승률이 최고한도 이내에 있을 확률이 낮을 것이다.
