US hedge-fund firm North Rock Capital Management LLC ramped up the expansion of its Asian operations, hiring former Millennium Capital Management portfolio managers Sayan Ghosh and Nilesh Banerjee.

Ghosh will anchor the firm’s Singapore presence and run a global long-short equities strategy while also working as its head of Asian investments, according to a person familiar with the matter, who requested not to be named because the matter is private. Banerjee, who was also at Millennium in Singapore until earlier this year, was registered to work in Hong Kong with North Rock in November, according to regulatory filings.
