Solaris will join other managers on the JANA Australian Equities platform.
"We liked Solaris because they were a good manager. The addition of the manager will enhance the platform's existing offering," JANA Investment Advisers division John Coombe said.
Coombe said the manager's style was different to the other managers on the platform and therefore would bring greater diversity to the investment returns.
Solaris is a style-neutral Australian equities fund manager, managed by nine people.
Solaris was formed in November 2007 after Suncorp's entire equities team defected to Pinnacle. Solaris is 60 per cent owned by staff and 40 per cent owned by Pinnacle.
