IEX is often labeled a "3% market share" venue, but what does that number really reflect? In this Boxes and Lines Lite, Ronan and JR chat with IEX’s Matt Weinberg (Head of Business Development) and Sam Stevens (Head of Business Analytics) to discuss a clearer way to think about institutional-accessible liquidity. They break down why total market share can be a misleading benchmark for routing, how "Institutional Market Share" better reflects where orders can actually interact, and what firms might be missing by benchmarking to the wrong number.
