GUNR approaches the global natural resources industry with a few twists. The fund provides exposure in traditional natural resources industries, particularly in energy, agriculture, precious or industrial metals, timber and water. Notably, GUNR extends its coverage to include 'upstream' businesses like containers and packaging, commercial services, and paper and forest products. To curate the portfolio, the funds underlying index selects 120 stocks using a proprietary methodology. It then caps weightings at the regional and sector level, minimizing the impact of firms of more popular names in the portfolio. Overall, GUNR has a broad and diverse take on a market that lends itself to concentration. The index is reconstituted semi-annually and rebalanced quarterly.
