Seen as a Large Buy-Side Firm

The Street recognizes Tourmaline as a large buy-side firm because we represent the flow of more than 350 institutional clients and we do not compete with the sell-side on any lines of business. Tourmaline clients receive significant benefit from the firm’s collective size. This includes access to the best sell-side tools, liquidity and market intelligence needed to achieve best execution.

Whether it’s an emerging fund that wants to outsource its entire trading function or a global asset manager that needs to supplement its existing capabilities, Tourmaline tailors its solution to meet a firm’s specific requirements. With us, clients can outsource as much or as little of their trading as they need while maintaining full control.

Four service models to accommodate clients with $50 million AUM to $1 trillion AUM: 1) fully outsourced solutions, 2) supplemental trading resources, 3) special situations, 4) custom in-house trading solutions
