[ A D V E R T O R I A L ] Meeting the growing demand from the buy-side for large-in-scale trading Mark Pumfrey, head of EMEA at Liquidnet discusses the changing nature of the dark landscape ahead of MiFID II. “A s Europe grapples with many changes, impending regulations such as MiFID II will usher in a new era for institution- al liquidity discovery, with many reassessing how, where, and why they trade in the dark.

The rise of LIS In August 2016, Rebecca Healey, Liquidnet’s head of market structure and strategy in EMEA, published a report based on interviews with 53 global heads of trading managing $13.5 trillion of assets – the results (in the chart below) show that the amount of LIS trading would have to increase to around 27% of the dark market to meet buy-side demand. Since the study, we have seen the amount of LIS trading nearly double in a year from 5% in H1 2016 to 9.6% in April 2017. Mark Pumfrey, head of EMEA, Liquidnet If this trend continues and the amount of LIS dark trading continues to rise, there will be a need for a complete rethink of how to create, consolidate, and access dark blocks. Some ideas suggested include aggregating flow to create
