Key Takeaways

  • ETFs trade on exchanges throughout the day at market prices, not just once daily like mutual funds.
  • ETF prices may differ from NAV - trading at a premium (above NAV) or discount (below NAV).
  • Authorized Participants (APs) keep ETF prices aligned with NAV through arbitrage.
  • ETFs are generally more tax-efficient than mutual funds due to in-kind creation/redemption.
  • UITs have FIXED portfolios that do NOT change over the trust's life.
  • UITs have a set maturity date; mutual funds and ETFs do not.
  • Leveraged ETFs reset DAILY and are NOT suitable for long-term buy-and-hold strategies.
  • Inverse ETFs profit when the underlying index declines.

ETFs and Unit Investment Trusts

Exchange-Traded Funds (ETFs) and Unit Investment Trusts (UITs) are alternatives to mutual funds with distinct characteristics.

Exchange-Traded Funds (ETFs)

ETFs combine features of mutual funds and individual stocks, offering diversification with intraday trading flexibility.

ETF vs. Mutual Fund Comparison

FeatureETFMutual Fund
TradingThroughout the day on exchangesOnce daily at 4:00 PM NAV
PricingMarket price (may differ from NAV)NAV only
Order TypesMarket, limit, stop ordersMarket orders only
Minimum InvestmentOne shareMay have minimums ($1,000+)
Expense RatiosGenerally lowerGenerally higher
Tax EfficiencyMore efficientLess efficient
CommissionsBrokerage commissionsNone (no-load) or loads
Short SellingAllowedNot allowed

Premium and Discount

ETFs can trade at prices different from their Net Asset Value:

SituationDefinitionImplication
PremiumMarket Price > NAVBuying above intrinsic value
DiscountMarket Price < NAVBuying below intrinsic value
At NAVMarket Price = NAVFair value

Authorized Participants and Arbitrage

Authorized Participants (APs) are market makers approved by the ETF issuer to create or redeem ETF shares.

The Creation/Redemption Process

ProcessWhat Happens
CreationAP delivers basket of underlying securities to ETF; receives creation units (typically 25,000-50,000 shares)
RedemptionAP delivers ETF shares to issuer; receives underlying securities

Why This Matters

BenefitExplanation
Price AlignmentArbitrage keeps ETF price close to NAV
Tax EfficiencyIn-kind transfers avoid taxable events
Lower CostsTransaction costs borne by APs, not fund

Arbitrage Example:

  • If ETF trades at a premium: APs create new shares (sell ETF, buy underlying) → increases supply → price falls toward NAV
  • If ETF trades at a discount: APs redeem shares (buy ETF, sell underlying) → decreases supply → price rises toward NAV

Exam Tip: The creation/redemption mechanism is why ETFs are more TAX-EFFICIENT than mutual funds. Securities are exchanged in-kind, not sold for cash.

Leveraged and Inverse ETFs

These complex products require special understanding:

ResetDailyDaily
Suitable ForShort-term trading onlyShort-term trading only
NOT Suitable ForLong-term buy-and-holdLong-term buy-and-hold

Daily Reset Problem

Leveraged ETFs reset daily, which causes compounding effects that can significantly differ from expected returns over longer periods.

Example: Index rises 10% then falls 10%

InvestmentDay 1Day 2Net Result
Index: 100+10% → 110-10% → 99-1%
2x ETF: 100+20% → 120-20% → 96-4%
3x ETF: 100+30% → 130-30% → 91-9%

Exam Tip: Leveraged and inverse ETFs are for DAILY trading ONLY. They reset daily and should NOT be held long-term. This is a common exam topic.

Unit Investment Trusts (UITs)

UITs are investment companies with fixed portfolios and set maturity dates.

UIT Characteristics

FeatureDescription
PortfolioFixed at creation - securities do NOT change
ManagementNo active management after creation
Maturity DateSet termination date
Sales ChargeFront-end load
ExpensesLower than mutual funds (no management fee)
DistributionsPass through all income to unit holders

How UITs Work

  1. Sponsor creates trust with fixed portfolio
  2. Units sold to investors at Public Offering Price
  3. Portfolio remains unchanged (no trading)
  4. At maturity, securities sold and proceeds distributed
  5. Unit holders can redeem before maturity at NAV

Comparison: Mutual Fund vs. ETF vs. UIT

ManagementActive or passiveUsually passiveNone (fixed)
TradingEnd of day at NAVIntraday on exchangeThrough sponsor
MaturityPerpetualPerpetualFixed date
Portfolio ChangesYesYesNo

Sales ChargesFront/back-end loadsCommissionsFront-end load

Exam Tip: UITs have FIXED portfolios that don't change and have a SET maturity date. This is different from mutual funds and ETFs which continue indefinitely.
