Exchange-traded funds (ETFs) have revolutionized investing by offering low-cost, diversified exposure to markets. This guide explains how they work and why they have become so popular.
ETF Basics
An ETF is a basket of securities that trades on an exchange like a stock. When you buy an ETF share, you own a proportional interest in the underlying portfolio. ETFs can track indices, sectors, commodities, or other assets.
How ETFs Are Created and Traded
Authorized participants (large financial institutions) create and redeem ETF shares by exchanging baskets of underlying securities with the ETF provider. This creation/redemption process helps keep ETF prices close to their net asset value.
Types of ETFs
- Index ETFs: Track market indices like the S&P 500
- Bond ETFs: Provide fixed-income exposure
- Sector ETFs: Focus on specific industries
- International ETFs: Offer global market access
- Commodity ETFs: Track resources like gold or oil
ETF Advantage
ETFs typically have lower expense ratios than mutual funds. For example, a typical S&P 500 index ETF might charge 0.03% annually compared to 1% or more for an actively managed mutual fund.
