BlackRock, one of the world’s leading providers of investment, advisory and risk management solutions, completed the investment in TXSE Group, the parent company of the Texas Stock Exchange. Financial terms were not disclosed. "Changes in equities trading markets are driving more volume to exchanges and more choices for issuers and sponsors. TXSE will ultimately create more competition around quote activity, liquidity and transparency, resulting in more consistent and reliable markets that benefit investors, global issuers and liquidity providers alike," James Lee, TXSE Group Founder and CEO.
