When traders leave investment banks for hedge funds, it doesn't always work out. For whatever reason, the tenure of the ex-bank traders can be short. Historically, some hedge funds have had a reputation for being particularly demanding - and none more so than Brevan Howard.
The UK's Financial Conduct Authority (FCA) Register suggests that two traders who joined Brevan Howard from investment banks have followed in the footsteps of many, many others and left the hedge fund within around 36 months of joining,
James Fauset, a former head of hedge fund sales at Goldman Sachs in London, who joined Brevan in April 2014, left the fund's London business on January 14, according to the FCA.
Asif Ghiawadwala, a former co-head of FX options at Westpac who joined Brevan on 15th November 2013, left the London business one day later, according to the FCA.
Neither man has re-registered elsewhere.
Of course, it's always possible that Fauset and Ghiawadwala are off to work in Brevan's Geneva office - although this looks a lot less likely ever since the fund abandoned its Geneva office in mid-2015. Last time we looked, it only had one trader working there.
Brevan Howard didn't immediately respond to a request to comment.
