An exchange-traded fund (ETF) is a type of pooled investment fund that operates much like a mutual fund. Typically, ETFs will track a particular index, sector, commodity, or other assets, but unlike mutual funds, ETFs can be purchased or sold on a stock exchange the same way that a regular stock can. An ETF can be structured to track anything from the price of an individual commodity to a large and diverse collection of securities. ETFs can even be structured to track specific investment strategies.

 Investing in ETFs can offer investors a convenient and low-cost way to gain exposure to a diversified portfolio of stocks. However, like any investment, it is important for investors to carefully consider their investment goals, risk tolerance, and time horizon before investing in ETFs. It is also recommended to consult with a financial advisor before making any investment decisions.
