국민연금이 2056 년 고갈될 수 있다는 전망이 나오면서 연금소득에 대한 국민들의 불안감이 커졌다. 노후를 위해 미리 대비해야한다는 인식이 커지며 자동으로 투자해주는 '로보어드바이저'에 대한 사회적 관심이 함께 높아졌다. 본 연구에서는 기존 시중 은행들의 펀드 기반 로보어드바이저가 아닌 기업 재무 정보, 수정 종가 데이터를 이용한 직접 투자를 고안하였다. LGBM 알고리즘으로 포트폴리오를 구현해본 결과 실제 퀀트 투자에서 사용되는 지표들이 주식의 변화를 예측하는데 효과가 있음을 확인할 수 있었다.

Starting from 2010, blockchain technology, along with the development of artificial intelligence, has been in the spotlight as the latest technology to lead the 4th industrial revolution. Furthermore, previous research regarding blockchain's technological applications has been ongoing ever since. However, few studies have been examined the standards for classifying the blockchain economic ecosystem from a capital market perspective. Our study is classified into a collection of interviews of software developers, entrepreneurs, market participants and experts who use blockchain technology to utilize the blockchain economic ecosystem from a capital market perspective for investing in stocks, and case study methodologies of blockchain economic ecosystem according to application fields of blockchain technology. Additionally, as a way that can be used in connection with equity investment in the capital market, the blockchain economic ecosystem classification methodology was established to form an investment universe consisting of global blue-chip stocks. It also helped construct an intelligent portfolio through quantitative and qualitative analysis that are based on quant and artificial intelligence strategies and evaluate its performances. Lastly, it presented a successful investment strategy according to the growth of blockchain economic ecosystem. This study not only classifies and analyzes blockchain standardization as a blockchain economic ecosystem from a capital market, rather than a technical, point of view, but also constructs a portfolio that targets global blue-chip stocks while also developing strategies to achieve superior performances. This study provides insights that are fused with global equity investment from the perspectives of investment theory and the economy. Therefore, it has practical implications that can contribute to the development of capital markets.
