Strategic Reading
Japannext matters because it tests whether Japanese equity execution is a single-exchange world or a routed market. Watch:
- retail broker SOR adoption (e.g. routing into Rakuten Securities / SBI Securities);
- best-execution policy revisions (FIBO index tracks the registered operators);
- spread / tick-size differences;
- nighttime liquidity;
- ownership and strategic alignment with SBI HD / Cboe-related market structure (peer venues are ODX and the parent TSE).
