ETFs, or exchange-traded funds, are financial instruments that allow traders to manage a variety of assets—such as stocks, bonds, commodities, and other securities—from the convenience of their accounts. Each ETF consists of a pool of assets that are bought and sold as a single stock.

When purchasing an ETF share, investors gain proportional ownership in a basket of assets, effectively investing in an entire segment of the market. This structure makes ETFs a popular tool for portfolio diversification. The ETF market is rapidly expanding, with annual growth rates projected between 15% and 30%, offering traders more opportunities to access various market sectors.
