The GAMCO Global Gold, Natural Resources & Income Trust functions as a closed-end equity mutual fund, initially established by GAMCO Investors, Inc., and currently under the management of Gabelli Funds, LLC. It strategically allocates capital across global public equity markets. The trust primarily focuses its investments on companies fundamentally involved in the gold and natural resources industries. This encompasses businesses engaged in activities such as the discovery, extraction, manufacturing, refining, distribution, or trading of gold, as well as entities that finance, manage, oversee, or operate gold-related ventures. Furthermore, it holds equity in firms predominantly active in the exploration, production, or supply of various natural resources, including commodities like natural gas, petroleum, paper, agricultural products, timber, and a diverse range of metals and minerals. Its portfolio also extends to supporting sectors, such as transportation services and equipment manufacturers. A distinctive aspect of its investment methodology is the strategic utilization of call options. To evaluate its performance, the fund benchmarks its portfolio against multiple indices: the CBOE S&P 500 Buy/Write Index, the Philadelphia Gold & Silver Index, the Energy Select Sector Index, and the Barclays Government/Credit Bond Index. Founded on January 4, 2005, the GAMCO Global Gold, Natural Resources & Income Trust is domiciled in the United States. It was previously known as GAMCO Global Gold, Natural Resources & Income Trust by Gabelli.
