Overview

Marinya Capital is the family office of John B. Fairfax, Nick Fairfax and their families, set up in 2012 when they left Cambooya, the office shared with John's siblings. It is headquartered in Sydney with operations in London and Dallas. It runs a global, beta-constrained, concentrated long equity strategy of 10 to 15 public and private positions, a small portfolio of external managers and a cash balance used for hedging. Its predecessor vehicle Marinya Holdings was the largest shareholder of Fairfax Media until late 2010 and sold its Landis+Gyr stake in 2011.

Investment thesis

A beta-constrained, global concentrated long equity investor: 10 to 15 public and private long equity positions make up most assets, with equity beta managed actively within 0.2 to 0.7 and active currency and macro hedging.
