The growth in SSO trading follows the expansion of eligible issues for market making that began in August 2026. Contributing factors include robust performance in the Tokyo Stock Exchange’s equity market, heightened trading activities linked to investment catalysts like earnings reports, and greater interest from a wider range of investors.
OSE plans to add two more issues to the market making eligibility list: Japan Physical Gold ETF (1540) and Kioxia Holdings Corporation (285A), starting in November 2026, in response to investor demand.
