Atlantis Investment Management, the London-headquartered Asian equities asset manager, has boosted its Japan team with the addition of portfolio advisor Sean Lenihan.

In his new role Lenihan will be responsible for stock research, portfolio management and client liaison, the firm said in a statement.

Lenihan was latterly Tokyo branch manager at TY Advisers and his earlier career includes a seven-year stint at Schroders’ Japanese investment management arm, first as a Japanese large cap equity analyst and then as an analyst and portfolio manager for small and mid cap portfolios.

Atlantic has some $4.4 billion in assets under management, as at the end of June.
