Exchange-Traded Funds (ETFs)
ETFs combine features of both mutual funds and stocks. They are registered investment companies, but they trade on exchanges throughout the day. The creation/redemption mechanism that keeps their prices in line with NAV is a favorite exam topic.
Structure and Trading
- Registered investment companies whose shares trade on exchanges throughout the day at market-determined prices
- Unlike mutual funds, ETFs are not forward-priced; they trade intraday like stocks
- Investors buy and sell ETF shares through a broker on the secondary market
- May trade at a slight premium or discount to NAV (but the creation/redemption mechanism keeps this tight)
Creation and Redemption Mechanism
This is the key mechanism that makes ETFs work. It involves authorized participants (APs), which are large institutional investors:
Creation process:
- AP assembles a basket of the underlying securities matching the ETF's portfolio
- AP delivers the basket to the ETF sponsor
- ETF sponsor issues creation units (large blocks, typically 50,000 shares) to the AP
- AP can then sell individual ETF shares on the exchange
Redemption process:
- AP delivers creation units back to the ETF sponsor
- ETF sponsor delivers the basket of underlying securities to the AP (in-kind)
Why this matters:
- The in-kind exchange keeps the ETF market price close to NAV (arbitrage opportunity if prices diverge)
- APs profit from any premium/discount by creating or redeeming shares, which brings the price back in line
- Individual investors do NOT interact with this process. They simply buy and sell on the exchange
Think of it this way: If an ETF trades at a discount to NAV, APs buy cheap ETF shares on the exchange, redeem them for the underlying securities (worth more), and pocket the difference. This buying pressure pushes the ETF price back up toward NAV. The reverse happens if the ETF trades at a premium.
Exam Tip: Gotchas
- Individual investors do NOT create or redeem ETF shares. Only authorized participants interact with the ETF sponsor. Retail investors buy and sell existing shares on the exchange.
- The creation/redemption process uses in-kind exchanges (securities for shares), not cash. This is what drives ETF tax efficiency.
Tax Efficiency
ETFs are generally more tax-efficient than mutual funds because of the in-kind creation/redemption process:
- In-kind redemptions do not trigger capital gains for the fund (unlike mutual fund cash redemptions)
- ETF shareholders typically only realize capital gains when they sell their own shares
- Mutual funds, by contrast, must distribute capital gains to all shareholders when the fund sells securities at a profit
- This means a mutual fund investor can owe taxes on gains even if they didn't sell any shares
Exam Tip: Gotchas
- A mutual fund investor can owe capital gains taxes without selling a single share. When the fund sells securities at a profit, it distributes those gains to all shareholders. ETF investors typically only realize gains when they sell their own shares.
Types of ETFs
| Type | Strategy | Key Consideration |
|---|---|---|
| Index ETFs | Track a specific index (S&P 500, Nasdaq, Russell 2000) | Most common type; low expense ratios |
| Actively managed ETFs | Portfolio manager makes investment decisions | Higher expense ratios than index ETFs |
| Leveraged ETFs | Seek to deliver multiples (2x, 3x) of the daily return of an index | Designed for short-term trading ONLY |
| Inverse ETFs | Seek to deliver the opposite of the daily return of an index | Designed for short-term trading ONLY |
Leveraged and inverse ETFs are designed for short-term trading only. Compounding effects make them unsuitable for long-term holding. A 2x leveraged ETF held over multiple days can significantly deviate from 2x the index's cumulative return.
Think of it this way: A 2x leveraged ETF aims for 2x the daily return, not 2x the cumulative return. If an index drops 10% one day and rises 10% the next, the index is down 1% overall. But the 2x ETF drops 20% then rises 20%, ending down 4%. Over time, this compounding drag gets worse.
Exam Tip: Gotchas
- Leveraged and inverse ETFs are for short-term trading ONLY. They reset daily, so compounding makes them unsuitable for buy-and-hold investors.
ETFs vs. Mutual Funds
| Feature | ETF | Open-End Mutual Fund |
|---|---|---|
| Trading | Intraday on exchange | Forward-priced, once daily at NAV |
| Minimum investment | Price of one share | May have minimums ($500-$3,000+) |
| Sales charges | Brokerage commission | Front-end or back-end loads (or no-load) |
| 12b-1 fees | Rarely | Common |
| Tax efficiency | Higher (in-kind redemptions) | Lower (cash redemptions trigger gains) |
| Short selling | Allowed | Not allowed |
| Margin | Allowed | Not allowed (Section 12(a)) |
| Limit/stop orders | Available | Not available (market orders only at NAV) |
Exam Tip: Gotchas
- Mutual fund shares CANNOT be purchased on margin or sold short (Investment Company Act of 1940, Section 12(a)). ETF shares can be margined and shorted because they trade on exchanges like stocks.
- If it trades on an exchange, it can be margined and shorted.
- ETFs rarely charge 12b-1 fees, unlike many mutual funds.
