Gold is one of the best performing assets so far this year, and despite a pullback here and there, investors say the fundamentals are in place for more gains in the coming months.

Gold prices have been on a tear all year, but the love hasn't transferred to exchange-traded funds that invest in the precious metal. But now, the tides are turning.

Getting into gold can be done through ETFs, including one that tracks the physical yellow metal and another that invests in gold mining companies.

Exchange-traded funds, or ETFs, are baskets of securities traded on exchanges that may offer investors greater diversification, less risk and fewer fees.
