At the world’s biggest publicly traded hedge fund, the human sales team is beating the market-trading computers hands down. Assets under management at Man Group AG climbed to $113.7 billion in the first half of the year. That’s testament to the persuasive powers of its sales force. Sales climbed to almost $20 billion, up 14 percent compared with the year-earlier period. Almost every category that Man offers its customers, including absolute return, systematic and discretionary, attracted more money from customers. Net inflows rose to a record $8.3 billion.
