A gold ETF (Exchange-Traded Fund) is a type of investment fund that tracks the price of gold. It allows investors to buy shares that represent a portion of the fund's gold holdings, making it easier to invest in gold without needing to buy physical gold bars or coins. Gold ETFs are traded on stock exchanges, similar to stocks, which means they can be bought and sold throughout the trading day. This provides liquidity and flexibility for investors who want exposure to gold prices without the complexities of storage and security associated with physical gold.
