The price returns of Korea’s most sustainable companies since 2007 proof beyond doubt that sustainable investment is profitable, given the right research approach. The “SolA Sustainable 50” has consistently outperformed the markets every year since inception in 2007 by margins that exclude statistical coincidence. Interestingly, the portfolio also outperformed an actively managed fund based on the SolAbility ESG research, indicating that long-term sustainable investment is a safer and more profitable investment approach or can be more in times of market volatility. The portfolio has also outperformed ESG benchmarks ( DJSI Korea and KRX SRI), indicating that sustainable investment returns depend on the quality of the research and methodology.
