Key Insights
- Exchange-Traded Funds (ETFs) are investment funds that trade on stock exchanges like individual stocks.
- This module explains how ETFs work, their advantages over mutual funds, types of ETFs, and how to evaluate them.
Overview
Exchange-Traded Funds (ETFs) are investment funds that trade on stock exchanges, combining the diversification benefits of mutual funds with the trading flexibility of individual stocks. ETFs have grown explosively over the past two decades, revolutionizing how investors access markets, sectors, and strategies. They offer low costs, tax efficiency, and transparency compared to traditional mutual funds.
ETFs can track broad market indices like the S&P 500, specific sectors like technology or healthcare, commodities like gold, or implement active strategies. The creation and redemption mechanism involving authorized participants keeps ETF prices closely aligned with their net asset value. Investors can buy and sell ETF shares throughout the trading day at market-determined prices.
Key Concepts
- Net Asset Value: The per-share value of an ETF's underlying holdings, calculated at the end of each trading day.
- Authorized Participant: A financial institution that creates or redeems ETF shares to keep market prices aligned with NAV.
- Expense Ratio: The annual fee charged by an ETF as a percentage of assets under management.
- Tracking Error: The difference between an ETF's returns and the returns of its underlying benchmark index.
- Passive vs Active Management: Passive ETFs track an index; active ETFs rely on manager decisions to outperform.
Key Takeaways
- ETFs combine mutual fund diversification with stock-like trading flexibility and intraday pricing.
- The creation/redemption mechanism keeps ETF prices aligned with underlying asset values.
- Expense ratios for passive ETFs are significantly lower than actively managed funds.
- Tracking error measures how closely an ETF follows its benchmark index.
