In his new role, London-based Stenhouse will also continue his former responsibilities as head of product, and will manage Turquoise Europe, as well as work to build out the venue’s footprint and growth across Europe.
Stenhouse’s new appointment marks an extension of his ongoing career at LSEG, having initially joined the group working in product development in 2007, before working his way up the ranks to his most recent position as co-head of equities trading and head of product.
The promotion also follows further developments in LSEG’s equities business in recent months, with former SIX head of equity products and quant research Simon Mason joining as firm’s new head of market structure and new products in November 2025, as revealed by The TRADE at the time.
