ETF (Exchange-Traded Fund)

A type of investment fund that trades on stock exchanges and holds a basket of assets like stocks, bonds, or commodities, offering diversification in a single purchase.

Exchange-Traded Funds (ETFs) are investment vehicles that combine the diversification of mutual funds with the trading flexibility of individual stocks. They are the building blocks of most robo-advisor portfolios and index investing strategies.

How ETFs Work

  • An ETF holds a collection of assets (stocks, bonds, commodities) that track an index or strategy
  • You buy and sell ETF shares on stock exchanges just like regular stocks
  • Prices fluctuate throughout the trading day
  • Most ETFs passively track an index (like the S&P 500), keeping costs very low

  • **Bond ETFs**: Provide fixed-income exposure (BND, AGG)
  • **International ETFs**: Access foreign markets (VXUS, EFA)
  • **Sector ETFs**: Focus on specific industries (XLF for financials, XLK for tech)
  • **Commodity ETFs**: Track gold, oil, or other commodities (GLD, USO)

FAQ

What is the difference between an ETF and a mutual fund?

ETFs trade on exchanges throughout the day like stocks, while mutual funds are priced once daily. ETFs typically have lower expense ratios, greater tax efficiency, and no minimum investment requirements. However, mutual funds may offer more active management options.
