CEF - Gold, Oil, Copper and Silver That brings me to the GAMCO Global Gold, Natural Resources & Income Trust (GGN). The closed end fund currently trades under $4.00, despite the sum of its parts being valued above this level. GGN gives investors a 9.9% annual distribution and taps into various natural resources and mining giants. Investors will get access to Newmont Corporation, Franco-Nevada, Barrick Gold, and Rio Tinto (RIO) on the gold mining side. On the energy side, the fund owns Exxon Mobil (XOM), Chevron (CVX), and Shell. Materials comprise 41.6% of this fund, while oil and gas represent 34% of the portfolio. This is a little riskier than traditional methods, but investors can profit from the combination of the near 10% yield and 6.4% discount to NAV. These giants are a good hedge against inflation and the oil companies are pushing into renewals as well.
