Rokos Capital Management, the London-headquartered global macro hedge fund firm founded by Chris Rokos, has appointed Matthew Sebag-Montefiore, who has been with the firm since 2018, as its new Chief Executive Officer, according to a report by Bloomberg. The report cites an investor letter seen by Bloomberg News as confirming that Sebag-Montefiore will take on the role, which has been vacant since the departure of former CEO Mark Edwards earlier this year, pending regulatory approval. Rokos, which manages $17.9bn in assets, has posted a strong 20.6% gain so far this year, according to unnamed sources sources familiar with the matter, far in excess of the average 6.1% return for macro hedge funds tracked by Bloomberg. Sebag-Montefiore originally joined Rokos Capital Management as chief strategy officer and stepped in as interim chief operating officer in March.
