Mr Ackman is executive chairman of HHH, who acquired Vantage for $2.1 billion this year and then recruited former Arch Capital Group chief executive Marc Grandisson as executive chairman of the insurer. Part of Vantage’s transformation involves a much greater allocation to common stocks in Vantage’s investment portfolio.

Mr Grandisson said Vantage would put underwriting profit ahead of premium volume and maintain conservative reserving while expanding and diversifying its business.
