Summary
Sava Mihic has launched his own hedge fund after more than a decade working largely out of public view at Platinum Asset Management, the ASX-listed global equities manager founded by billionaire investor Kerr Neilson, according to the Australian Financial Review (AFR). The AFR reports that Mihic has emerged from what it describes as "stealth mode" now that Platinum is no longer operating in its former form.

Mihic is running the fund through Mihic Fund Management. Per the AFR, the venture has the backing of Neilson and another Platinum alumnus, Jim Simpson. Publisher materials identify the fund as Adamantos and describe Mihic as Platinum's former head of quant, who is now set to run it.

Neilson founded Platinum in 1994 and managed its global equity portfolios for 24 years before handing the reins to Andrew Clifford. He stepped down from the Platinum board in 2022. Neilson's endorsement gives Mihic's launch notable credibility within Australian institutional and wholesale investment circles, though the available material does not disclose fund size, strategy details or investor commitments.
