ETF Definition
An exchange‑traded fund, or ETF, is an investment fund that trades on a stock exchange and holds a basket of assets. This ETF definition applies globally, although in the United States ETFs must register with the SEC as an open‑end investment company or, in some cases, as a unit investment trust. ETFs pool money from many investors and invest in assets such as shares, bonds, short‑term instruments, or other securities. Each ETF unit represents part ownership of the fund’s portfolio, and investors buy and sell these units on an exchange at market prices. [1]
How an ETF Works
An ETF holds a basket of assets and lists its units on an exchange. Investors then buy and sell those units throughout the trading day at market prices. This structure increases flexibility because ETFs trade continuously, while mutual funds trade only once per day. It also improves transparency because most ETFs publish their holdings regularly.
What ETFs Invest In
ETFs cover a wide range of markets. Some track broad share indexes such as the S&P 500. Others focus on bonds, commodities, sectors, or themes. This variety allows investors to build diversified exposure without selecting individual assets.
Why ETFs Are Popular
ETFs attract interest for several reasons. They offer easy diversification because one ETF can hold dozens or hundreds of assets. They also tend to charge lower fees than many actively managed funds. In addition, they trade instantly during market hours, which gives investors more control over timing. These features make ETFs a practical way to access markets.
