GDX (Gold Miners ETF)

GDX is an exchange-traded fund (ETF) that invests in companies involved in gold mining. Rather than buying physical gold, it allows investors to gain exposure to the gold mining industry through a single, tradable security. Its value rises when gold prices increase and when gold mining companies perform well, making it a way to track the overall health and profitability of the gold mining sector. GDX provides diversification across multiple miners, reducing individual company risk, and offers a convenient way for investors to speculate on or hedge against gold price movements.
