Pinggera will work alongside Johan Badenhorst, who will focus on trading and risk management, and former colleague Paul Zoltowski, a client relationship manager.
Their first fund, a diversified growth strategy with downside protection, will launch on 2 January.
Investments will be made in five strategies. Four says the fund will actively allocate to eight regional and country equity indices to gain directional exposure, and to four non-directional or low beta investment themes providing exposure to active alpha, emerging markets, equity alternatives and real assets.
Pinggera resigned from Insight Investments earlier this year where he was head of its multi-asset group and responsible for several retail funds.
Derrick Dunne, a founding partner of Four, said: “We have been very interested in this fast growing space and have spent a good deal of time identifying the right team for us. We are delighted to have attracted such a high profile and experienced team.
“There is strong demand from clients for high quality multi-strategy portfolios and we believe that the approach employed by Mike has significant differentiators that will be attractive to a wide range of investors.”
