JPX-Nikkei400, etc. (JPX-Nikkei Co-brand Index)

Aim of the index

logo

In recent years, there has been a growing recognition generally that management that is conscious of human capital is crucial for improving their competitiveness and corporate value. For example, from the fiscal year ended March 2023, Japanese listed companies have been required to disclose information on human capital in their annual securities reports. The aim of JPX-Nikkei Index Human Capital 100 is to reflect the stock price trends of TSE-listed companies that are improving their disclosures and efforts related to human capital.
JPX-Nikkei Index Human Capital 100 will consist of 100 constituents. Initially, the candidates for inclusion will be selected from the constituents of JPX-Nikkei Index 400 in descending order by the candidate's comprehensive human capital score. The candidate's comprehensive human capital score will consist of a base score and extra points. For the candidate's base score, we will use its human capital score, which is calculated by ESG Book based on the ESG information disclosure standards of the Sustainability Accounting Standards Board (SASB). We will then add extra points to the candidate's base score whenever the candidate meets a condition that is considered important for Japanese companies to meet.
Through JPX-Nikkei Index Human Capital 100, we hope to create a virtuous cycle where widespread investment in the index encourages listed companies to make human capital-related improvements, which increases their corporate value and benefits investors, which then encourages further investment and improvements.
