Rokos rose to prominence while trading at Brevan Howard, the hedge fund he co-founded alongside Alan Howard and others.
He left Brevan in 2013 and launched his own hedge fund in September 2015 after settling a non-compete clause with his former employer.
Rokos’ global macro hedge fund became one of the most successful new launches in recent years. Its success was unusual because it came at a time when many investors were becoming increasingly disillusioned with hedge funds and started to withdraw from the asset class.
Rokos Capital Management was backed by The Blackstone Group, which invested $ 500 million. When it launched in September 2015, it raised $ 3.5 billion for its first hedge fund but was soft-closed it to new money shortly after.
Rokos’s ability to gather assets quickly is a rare success in an industry where startups have struggled to get off the ground.
However Rokos has a strong track record at Brevan Howard – a track record revealed in documents made public in 2014 when he and his former employer battled in court over the terms of his non-compete clause.
Court filings made public as part of a non-compete battle with Brevan Howard showed that Rokos twice made more than $ 1 billion in trading profits in a single year.
In 2007, the documents said, Rokos made $ 1.1 billion – some 27% of the total profits of the Brevan Howard Master Fund. In 2011 he went one better by making $ 1.3 billion, some 30% of the master fund’s profits.
Brevan Howard and Rokos settled the case in January 2015, paving the way for Rokos to launch his own hedge fund. His former colleague and Brevan Howard co-founder Alan Howard put some of his own money into the fund at launch.
Rokos’ fund returned about 9% for 2016 to the end of September.
