Exchange-traded funds (ETFs) are pooled investment securities that operate similarly to mutual funds but trade like individual stocks on exchanges. Typically, ETFs track specific indices, sectors, commodities, or other assets, offering diversification and liquidity at a lower cost than traditional mutual funds.
Key Takeaways
- Trading Flexibility: ETFs trade throughout the day like stocks, unlike mutual funds that transact only once after market close.
- Diversification: Hold hundreds or thousands of assets across industries, reducing single-stock risk.
- Cost-Efficiency: Lower expense ratios and fewer broker commissions compared to mutual funds.
- Transparency: Holdings are disclosed daily, unlike some mutual funds.
How ETFs Work
ETFs are structured to mirror the performance of their underlying assets—whether an index (e.g., S&P 500), sector (e.g., technology), or commodity (e.g., gold). Authorized participants (APs) facilitate creation/redemption processes to align ETF prices with net asset values (NAV).
Example:
The SPDR S&P 500 ETF (SPY), launched in 1993, tracks the S&P 500 and remains one of the most traded ETFs.
Types of ETFs
1. Passive vs. Active ETFs
- Passive: Track indices (e.g., SPY).
- Active: Managed by portfolio managers (higher fees).
2. Bond ETFs
Provide regular income via government/corporate bonds.
3. Stock ETFs
Offer exposure to specific sectors (e.g., Invesco QQQ for tech).
4. Commodity ETFs
Invest in physical goods like gold (GLD) or oil (USO).
5. Leveraged/Inverse ETFs
- Leveraged: Amplify returns (e.g., 2x S&P 500).
- Inverse: Profit from market declines.
6. Thematic ETFs
Target trends like ESG or AI.
How to Buy ETFs
- Choose a Platform: Online brokers (e.g., Robinhood, Fidelity) or robo-advisors.
- Research: Consider expense ratios, liquidity, and performance.
- Execute Trades: Buy/sell like stocks.
