American hedge fund boss Bill Ackman has made $2.6 billion by betting against the markets just days after stoking fears by saying 'hell is coming' and begging President Donald Trump to shut down the country amid the coronavirus pandemic. The Pershing Square Capital Management hedge fund manager said his firm had made $2.6billion from a one-off bet that the coronavirus outbreak would cause a global market crash. His firm seized upon bond market turmoil during the coronavirus crisis in buying 'credit protection on various global investment grade and high-yield credit indices'.
