An ETF, or Exchange-Traded Fund, is an investment fund that trades on a stock exchange like a regular stock. ETFs typically hold a basket of assets such as stocks, bonds, or commodities.

Many investors use ETFs because they provide instant diversification, low costs, and easy access to global markets. A single ETF can contain hundreds or even thousands of individual securities.

ETFs have become one of the most popular investment vehicles for long-term investors looking to build wealth efficiently.
