Pensions and Investments: Managers join together to boost trading transparency

“Our members' mission is clear: How can we get a better look at how we trade?” said Tyler Gellasch, executive director of the Healthy Markets Association, Washington, a non-profit group of money managers. “We are here because our members want a strong voice on market structure. Some others want the status quo; that's not who we are.”

“We want to improve the best practices of the industry, then get the policies and practices in place to do execution better,” Mr. Gellasch said. “Clearly there's a need for this.”
