Copley Equity Partners, a private investment firm that focuses on established businesses with significant growth prospects, completed a majority investment in Tourmaline Partners, an outsourced trading solutions firm. Financial terms were not disclosed. "We have followed Tourmaline closely for several years and have been impressed with their long-term vision and global expansion. Tourmaline has captured lightning in a bottle, as changes across the trading landscape – from MiFID II-driven unbundling, to liquidity fragmentation and cost pressures – have led the buy side to seek outsourced and supplemental trading solutions to gain efficiencies and improve trading performance," Peter Trovato, Copley Equity Managing Partner.
