The transaction, which has been approved by the Financial Services Authority, the UK financial regulator, means that DDQ is 100 per cent owned by the company’s board and staff.

DDQ’s management buyout draws a line under uncertainties surrounding the future of parts of the Dawnay Day International group of firms after the parent company hit financial troubles. Dawnay Day International has been put into administration.

“This transaction represents a combination of continuity and an exciting new beginning. Since the company was founded five years ago, we have always sought to offer our clients investments that give good returns and managed risk,” Mark Mathias, chief executive Officer of DDQ and founder of this business, said in a statement.

“We have been operating as a stand alone business, independently regulated by the FSA, for some years now, and we will continue to focus on investment returns, risk management and our clients,” Mr Mathias added.

DDQ was founded in 2003 and specialises in structured investments offering capital protection and in quantitative funds.

Dawnay Day Quantum becomes the next unit to hive itself off from Guy Naggar and Peter Klimt's sprawling real estate empire, which called in administrators in July after margin calls forced it to sell an investment at a steep loss.
