(Reuters) Just before Bill Ackman gave a presentation on Friday to defend one of his biggest investments, Valeant Pharmaceuticals, from allegations of accounting and insurance fraud, he was taunted by John Hempton, who runs a small hedge fund from Australia. It was the latest act in a long-running feud.
In an email he sent Ackman, who is one of the world’s best-known hedge fund managers, was a link to Hempton’s latest critique of the Canadian drug maker’s potential problems, one of the most detailed produced by anyone yet.
