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.

Therefore, we have decided to change our approach. This time, we aim to use the model to help us identify buy and sell points and formulate a trading strategy. We have also incorporated eight new feature indicators, with four being technical indicators and four being macroeconomic indicators, in the hope of improving our prediction results using these two facets of feature values.
