LONDON, Jan 23 (Reuters) - Eisler Capital has recruited Damien Bombelli, whose background in commodities could help the hedge fund bolster a less profitable part of its business, three people with knowledge of the move said on Monday. Bombelli, who has worked at investment firms and banks including Millennium Capital Management and JP Morgan Chase & Co., will join the $3.5 billion fund in a role allowing him to deal with client funds, according to the website of Britain's Financial Conduct Authority (FCA).
