Michael Platt’s BlueCrest Capital Management is the latest hedge fund firm to announce plans to return all outside money to clients. This works out to $7 billion of the London firm’s total $8 billion in assets, down from $14.4 billion at the beginning of the year. Several years ago Platt, a former J.P. Morgan swaps trader, reportedly told prospective investors he hoped to grow BlueCrest to $50 billion. Clients will receive 75 percent of their money before the end of January and 90 percent by the end of the first quarter, according to an announcement by the firm. It will continue to manage partner money. “Ongoing secular changes in the industry, including trends in fee levels, the cost of hiring the best trading talent, and the challenges in tailoring investment products to meet the individual needs of a large number of investors, have weighed on hedge fund profitability,” the firm said in its announcement. BlueCrest’s assets stood at $35.3 billion at the beginning of 2013. It subsequently spun off $9 billion in computer-driven assets to Systematica Investments, the computer-driven firm led by Leda Braga, who managed the firm’s BlueTrend fund. The firm also suffered from redemptions from its existing funds. Last year, Platt earned $800 million, ranking sixth on Alpha's Rich List, the fourth time he qualified for the top-25 list. ___
