Goldman Sachs has lost another trader to a hedge fund firm, with Rick Vaatsra leaving the bank's London office this month, to join multi-strategy major Millennium Management as a senior portfolio manager based in London.

Vaatsra spent over 10 years at Goldman Sachs, most recently as co-head of European index trading, having originally joined the bank as an equity derivatives trader back in November 2012.

Prior to Goldman Sachs, Vaatsra, who studied finance and economics at Erasmus University Rotterdam, according to his LinkedIn profile, spent over six years at Credit Suisse as a vice president.
