Osaka Exchange, Inc. (OSE) is pleased to announce that, effective September 1, 2025, it will expand the number of single stock options (SSOs) eligible for market making to 32 from the current 12 by adding issues on 20 new individual stocks. Eligible underliers will now comprise 30 individual stocks and 2 ETFs.
SSO Trading is on the Increase
To enhance the convenience of the SSO market, since fall 2024, OSE has had market makers continuously quote prices for SSOs on ten new individual stocks in addition to the existing two ETFs, creating a more accessible trading environment for investors for 12 securities in total. As a result, a diverse range of investors have started utilizing the market, and there has been a noticeable increase in transactions, particularly during auction sessions. We have also received requests from investors for further expansion of issues eligible for market making.
- ･"Market making" is a system that ensures market liquidity and promotes price stability by continuously offering buy and sell orders for specific issues.
