Evy Hambro is to take on the role of co-manager on the fund.
Hambro is already co-manager with Birch across a number of BlackRock’s existing offerings, including the world mining fund and the world gold fund.
Birch has managed the £1.53bn gold and general fund since 1999. The fund has returned 107.6 per cent over the past five years, according to figures from Morningstar. The fund has returned 32 per cent in the past three months.
Managing director Alex Hoctor-Duncan says: “Evy Hambro has been co-manager with Graham on almost every fund he runs at BlackRock, barring the gold and general fund, making this decision a logical one. We have a wealth of experience on the fund and it will continue to grow in strength.”
Hargreaves Lansdown investment manager Ben Yearsley says: “Despite this being a big fund that is in favour at the moment, I do not feel this news is that big a concern, given the huge team and infrastructure that BlackRock has in this area of the market.”
