Fund manager Peter Hall appears to have dusted a chunk of his significant personal fortune with his abrupt departure from the $1 billion-plus asset manager that bears his name.

The listed Hunter Hall entities confirmed in an ASX statement on Wednesday that Mr Hall had quit and the group is looking for a new chief investment officer without providing any reason for Mr Hall's departure. The decision came as a shock to funds management industry insiders and the company declined to comment further. Mr Hall, who also declined to comment, is said to be seeking a break from investing for personal reasons having found market conditions unsuited to his style and feeling increasingly uncomfortable with the direction politics is taking given his strong ideologies.
