Simon Luhr has resigned as chief executive at Marble Bar Asset Management (MBAM), the London-based hedge fund arm of the Eden Group, to pursue other opportunities in the alternative investment arena.

Following Luhr's resignation, Marble Bar plans to concentrate on building short-term long/short European equity funds in the mould of its existing Tomahawk and Jandakot hedge funds, which are overseen by Hilton Nathanson, founder and chairman of the firm.
