Exchange Traded Funds

Quick Answer

ETFs are legally structured as open-end funds or UITs under the Investment Company Act of 1940, but they trade on an exchange throughout the day like a stock instead of transacting directly with the fund at NAV. Authorized participants create and redeem shares predominantly in-kind, which keeps ETF prices close to NAV and makes ETFs more tax-efficient than mutual funds.

The exam tests both halves of that Quick Answer separately: the legal structure (open-end/UIT) and the trading behavior (exchange-traded, intraday). Do not let the exchange-trading feature trick you into calling an ETF a closed-end fund.


What Are the Basic Characteristics of an ETF?

  • Trade on exchanges throughout the day like stocks (continuous pricing)

  • Most ETFs are passively managed (track an index), though actively managed ETFs exist

  • 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.

How Does an ETF Compare to a Mutual Fund?

FeatureETFOpen-End Mutual Fund
TradingExchange, intradayEnd of day, forward pricing
PricingMarket price (may differ from NAV)NAV only
Minimum investmentPrice of one shareOften $1,000-$3,000
Tax efficiencyHigher (in-kind mechanism)Lower (capital gains distributions)
Expense ratiosGenerally lowerGenerally higher
Margin/shortPermittedNot permitted
Management styleMostly passive (index)Active or passive
Cost to buy or sellBrokerage commission, if the broker charges oneSales load or transaction fee, depending on share class and purchase channel

Exam Tip: Gotchas

  • ETFs can be bought on margin and sold short. Mutual funds cannot. This is a key distinction.
  • ETFs do not eliminate trading costs. An investor buys ETF shares through a broker, so a brokerage commission may apply. Mutual funds are not cost-free to buy either, because a sales load or transaction fee can apply. So "elimination of all brokerage commissions" is never an ETF advantage on the exam.

How Does the ETF Creation and Redemption Process Work?

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.

What Happens Step by Step?

Redemption is creation in reverse: the AP swaps ETF shares back for the underlying basket instead of the other way around.

Creation (New Shares):

StepAction
1Authorized Participant (AP) assembles basket of underlying securities
2AP delivers securities to ETF sponsor
3ETF issues new shares to AP
4AP sells ETF shares on exchange

Redemption (Remove Shares):

StepAction
1AP delivers ETF shares to fund
2ETF delivers basket of underlying securities to AP
3ETF cancels the redeemed shares
4AP sells securities in market

Who Are the 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 Does In-Kind Creation Matter?

  • Cash generally does not change hands between the ETF and the AP; the exchange is predominantly securities baskets for shares, though a small cash balancing amount may true up any gap between the basket's value and the creation unit's net asset value
  • In-kind redemption generally avoids realizing capital gains at the fund level, unlike a mutual fund redemption that may force the sale of portfolio securities for cash
  • Fewer capital gains distributions to shareholders as a result
  • Result: ETFs are generally more tax-efficient than mutual funds

How Does Arbitrage Keep the Price Near NAV?

  • ETF trades at a premium (above NAV): APs deliver the basket to the fund, receive new ETF shares, and sell those shares on the market. Supply increases, price falls back to NAV.
  • ETF trades at a discount (below NAV): APs buy the cheap ETF shares on the market, hand them to the fund, and receive the more valuable basket of 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 predominantly in-kind. A small cash balancing amount may true up the gap between the basket's value and the creation unit's net asset value, but the exchange is baskets of securities, not cash. This is why ETFs are more tax-efficient than mutual funds.
  • Only Authorized Participants can create/redeem. Retail investors trade on exchanges.
  • Track which side the AP hands over. At a discount, the AP hands the fund the cheap ETF shares and receives the more valuable basket; selling the basket comes afterward. Handing over the basket to receive ETF shares is creation, the premium trade.
  • ETF premiums/discounts are typically very small due to the AP arbitrage mechanism. Large, persistent premiums/discounts are a closed-end fund characteristic.

What Should You Check on Exam Day?

  • Can you state that an ETF is legally an open-end fund or a UIT, even though it trades like a stock?
  • Do you know that ETF creation and redemption happen in-kind through authorized participants, not directly with retail investors?
  • Can you explain why the in-kind mechanism makes ETFs more tax-efficient than mutual funds?
  • Do you know why AP arbitrage keeps ETF premiums and discounts small, and that a large, persistent gap points to a closed-end fund instead?
  • Can you compare ETFs and mutual funds on trading venue, pricing, minimum investment, and margin/short-sale eligibility?
