Exchange-Traded Funds (ETFs)

ETFs are a hybrid product that combines features of mutual funds and closed-end funds. They are structured as open-end funds (or UITs) under the Investment Company Act of 1940 (ICA) but trade on exchanges like stocks.


ETF Characteristics

  • Trade on exchanges throughout the day like stocks (continuous pricing)
  • Most ETFs are passively managed (track an index), though actively managed ETFs exist

Well-known index ETFs you should recognize:

  • Shares created and redeemed through an authorized participant (AP) mechanism using in-kind creation/redemption baskets
  • Tax-efficient - in-kind creation/redemption minimizes capital gains distributions
  • Generally lower expense ratios than comparable mutual funds
  • Can be purchased on margin and sold short
  • Can be bought and sold at market prices that may differ slightly from net asset value (NAV) (intraday premium/discount)
  • No minimum investment beyond the share price
  • Sold by prospectus

Exam Tip: Gotchas

  • ETFs are legally structured as open-end funds or UITs under the ICA, but they trade like stocks on an exchange. This is a common exam trap.

Exam Tip: Gotchas

  • ETFs can be bought on margin and sold short. Mutual funds cannot. This is a key distinction.

ETF Creation and Redemption Process

ETFs use a unique "in-kind" creation and redemption mechanism that keeps their market price close to NAV. This is the key reason ETFs are more tax-efficient than mutual funds.

How It Works

StepCreation (New Shares)Redemption (Remove Shares)
1Authorized Participant (AP) assembles basket of underlying securitiesAP delivers ETF shares to fund
2AP delivers securities to ETF sponsorETF delivers basket of underlying securities to AP
3ETF issues new shares to APETF cancels the redeemed shares
4AP sells ETF shares on exchangeAP sells securities in market

Key Participants

  • Authorized Participants (APs): Large institutional investors (typically broker-dealers) authorized to create/redeem ETF shares directly with the fund
  • Retail investors: Buy and sell on exchanges (cannot create/redeem directly)

Why In-Kind Matters

  • No cash changes hands between ETF and AP
  • No taxable event for the ETF (unlike mutual fund redemptions)
  • Fewer capital gains distributions to shareholders
  • Result: ETFs are generally more tax-efficient than mutual funds

Arbitrage Keeps Price Near NAV

  • ETF trades at a premium (above NAV): APs create new shares and sell on the market. Supply increases, price falls back to NAV.
  • ETF trades at a discount (below NAV): APs buy ETF shares and redeem for underlying securities. Supply decreases, price rises back to NAV.

Think of it this way: Imagine you could exchange a basket of apples for an "apple certificate" and vice versa at any time. If certificates sell for more than the apples are worth, you would buy apples, exchange them for certificates, and sell at a profit. This automatic arbitrage keeps ETF prices honest.

Exam Tip: Gotchas

  • ETF creation/redemption is in-kind (not cash). This is why ETFs are more tax-efficient than mutual funds.
  • Only Authorized Participants can create/redeem. Retail investors trade on exchanges.
  • ETF premiums/discounts are typically very small due to the AP arbitrage mechanism. Large, persistent premiums/discounts are a closed-end fund characteristic.
