Marex Spectron, the London-based financial and commodity derivatives broker, has reported a strong rise in profits for its 2010-11 financial year, as the firm took advantage of market volatility and booming trading in its core products.

Group revenues rose 45% to £148.5m, largely on the back of a rise in base metals trading, with adjusted operating profits jumping by two-thirds to £16.2m. The firm is a top-tier floor dealer and shareholder of the London Metal Exchange.
