In 2014, the CFA Institute in the US began discussing the incorporation of ESG (Environmental, Social, and Governance) factors into investment decision-making and business valuation. However, the measurement involved in each rating varies greatly, thus confusing users. Given this, TEJ released the “TESG Rating Index (TESG Rating) ” on March 31, 2022, a tool for reference in investment and credit. What’s more, we use the TESG Rating to explore its correlation with commonly-used valuation multiples, such as the price-to-book (P/B) ratio and price-to-earnings (P/E) ratio.
