SG Corporate & Investment Banking has hired three equity derivative flow sales officials to bolster its European business. Sonia Sidhom, previously at BNP Paribas, comes on board to cover sales to U.K. hedge funds, and Micael Niden and Frederik Slytaa join from Nordea, to cover Scandinavia. Yannick Mallegol, head of equity derivative flow sales in Paris, said the hires represent an expansion of its business. It has not had a flow sales presence in Scandinavia until now, and Sidhom was hired to reinforce its hedge fund sales team in London.
