Global Reach Meets Local Market Growth

For JAX, the partnership with TNS provides exposure to a broader international audience at a time when competition within Japan’s equities market is intensifying. Alternative venues are increasingly viewed as a way to improve price discovery, reduce costs and enhance execution options for both domestic and foreign participants.
