JP Morgan Asset Management is expanding its portfolio of natural resources funds with the launch of the JPM Global Mining Fund. Managed by Neil Gregson, the new fund aims to respond to investor demand for a focused mining sector fund.

The fund will invest primarily in companies engaged in mining or mining-related activities anywhere in the world. It will invest in 50-100 stocks and will be an all-cap fund.

“While the mining sector has performed strongly in the last two years, there is still good reason for continued allocation to it. In fact, as a team we believe that an exposure to metals, both precious and base, remains one of the most compelling investment opportunities in 2011 and beyond. Our investment approach on this fund will see us focusing on companies that can achieve growth of reserves and production, while at the same time identifying undervalued mining assets which will benefit the portfolio,” said Gregson, who joined the firm in 2010.
