ARC Group The move to buy the wealth data and indices of ARC Research was first announced by this news service in July. The completion of the sale of ARC Research and its ARC Wealth Indices – the world's largest proprietary dataset of investment outcomes for private investor portfolios – will underpin the ARC Group’s strategy to expand its advisory division, which advises on $25 billion in assets for international families and charities. “There is no better home for ARC Research and the ARC Wealth Indices than S&P DJI. We look forward to hearing of the continued growth and success of the Indices,” Stephen McMahon (pictured below), CEO of ARC Group, said. “But the ARC Group will not be resting on its laurels.
