Three stocks in ATS’s unquoted portfolio were written up – Metapack (a business that helps online retailers dispatch goods efficiently), All The Worlds Entertainment and Nanopore Technologies. The holdings in fund manager, Polar Capital : POLR, Africa Oil : AOL and Telford Homes :TEF also made significant positive contributions to performance.
