Kuhn is leaving to return to her native South Africa for personal reasons having run the India fund since its launch in December 2006. She joined Neptune in December 2005 as a senior analyst.
The £21.8m Neptune India fund has returned 22.07 per cent in the past 12 months compared with an average fall of 14.27 per cent in the IMA specialist sector to the end of June 2009. Kuhn also managed the £13.1m Asia Pacific opportunities fund.
A Neptune spokesman says: “Shelley Kuhn has advised us of her intent to return permanently to South Africa and, consequently, will be leaving Neptune at the end of the summer. In the interim, she is co-managing the Neptune India fund with Ewan Thompson.
Ewan Thompson also manages the Neptune emerging markets fund.
