A hedge fund has told investors it returned money to Saudi Arabia following the murder of columnist Jamal Khashoggi, according to people with knowledge of the matter. The move is a rare rebuke to one of the world’s most influential investors. Pharo Management (UK) LLP in December gave back about $300 million that it had previously managed for the kingdom’s central bank Saudi Arabian Monetary Authority, known as SAMA, one of the people said, asking not to be identified because the information is confidential.
