Mutual Funds and Other Pooled Investment Products

Updated for the 2026-2027 CFA® Level I curriculum.

A pooled investment vehicle lets many investors combine their money into one professionally managed portfolio. Instead of buying individual stocks or bonds, an investor buys a share of the pool.

CFA Level I tests whether you can identify how different pooled products are structured, priced, and traded, and how those differences affect cost and liquidity for investors.

Key Takeaways About Mutual Funds and Other Pooled Investment Products

• A pooled investment vehicle combines investor capital into one professionally managed portfolio, giving each investor diversification they could not easily build alone.

• Mutual funds are open-end funds priced once a day at net asset value (NAV).

• ETFs trade throughout the day on an exchange and use a creation/redemption process that keeps market price close to NAV.

• Closed-end funds issue a fixed number of shares at inception and can trade at a premium or discount to NAV.

• Fees, minimum investment size, and trading flexibility vary across pooled products and affect which vehicle fits a given investor.

• Level I questions often test whether you can classify a fund correctly from a short description of its trading and pricing behavior.

What You Need to Know for CFA Level I

• Know the basic structure of a pooled investment vehicle and why it exists.

• Be able to describe how mutual funds are priced and redeemed.

• Understand how ETF creation and redemption keeps market price near NAV.

• Recognize closed-end funds by their fixed share count and premium/discount behavior.

• Identify other pooled products such as hedge funds and private equity funds by their limited liquidity.

• Compare pricing, trading, liquidity, and cost across pooled products when given a short scenario.

What Is a Pooled Investment Vehicle?

A pooled investment vehicle collects money from many investors and invests it as one portfolio. Each investor owns a proportional share of the pool, not the underlying securities directly. This structure gives smaller investors access to diversification and professional management they could not achieve cost-effectively on their own.

Pooled vehicles fall within the broader asset management industry. A fund sponsor creates the vehicle, a portfolio manager runs it, and investors buy shares or units that represent a claim on the pool's assets. The main differences among pooled products come down to how shares are issued, how they are priced, and how investors can buy or sell them.

Mutual Funds

A mutual fund is an open-end fund. "Open-end" means the fund can issue new shares or redeem existing shares every business day, based on investor demand.

How Mutual Funds Are Priced

Mutual funds price shares once a day using net asset value.

Where:

•  = market value of all securities and cash held by the fund

• = fund expenses owed and other obligations

• = number of fund shares held by investors

NAV is calculated after markets close, so investors who place an order during the day receive that day's closing NAV, not a live price. This is different from how ETFs and closed-end funds trade.

Share Classes and Fees

Many mutual funds offer multiple share classes with different fee structures, such as front-end loads, back-end loads, or level-load structures. Level I does not require memorizing every fee type, but candidates should recognize that mutual fund costs reduce investor returns and vary by share class.

Exchange-Traded Funds

An exchange-traded fund (ETF) is also open-end, but it trades on an exchange throughout the day like a stock. Investors buy and sell ETF shares at the current market price, not once-daily NAV.

Creation and Redemption

ETFs use a creation and redemption mechanism run by authorized participants (APs). When an ETF's market price rises above NAV, an AP can create new shares by delivering the underlying securities to the fund, then sell those shares on the exchange. When the market price falls below NAV, an AP can redeem shares for the underlying securities. This process keeps the ETF's market price close to its NAV.

ETF Pricing and Trading

Because ETFs trade continuously, their price reflects real-time supply and demand, not just NAV. In normal market conditions, the creation/redemption mechanism keeps the gap between price and NAV small. During periods of market stress, this gap can widen.

Closed-End Funds and Other Pooled Products

A closed-end fund raises capital once, through an initial public offering, and issues a fixed number of shares. After the IPO, the fund does not create or redeem shares based on investor demand. Instead, existing shares trade on an exchange between investors.

Because the share count is fixed, a closed-end fund's market price can trade at a premium or a discount to its NAV, depending on investor demand for the shares themselves. This is a key difference from mutual funds and ETFs, where the creation/redemption process (or daily NAV pricing) keeps price and NAV closely linked.

Other pooled investment products include hedge funds, private equity funds, and venture capital funds. These vehicles typically have less liquidity than mutual funds, ETFs, or closed-end funds. Investors often face lock-up periods and redemption restrictions. Separately managed accounts (SMAs) are related but distinct: an SMA holds securities directly in the investor's own account rather than through a pooled fund structure.

Comparing Pooled Investment Products

The table below summarizes the distinctions Level I most commonly tests.

Worked Example

Scenario: An analyst describes three pooled products to a study group.

• Fund A issues and redeems shares daily and prices once per day after market close.

• Fund B trades all day on an exchange, and authorized participants create or redeem shares to keep its price near NAV.

• Fund C issued a fixed number of shares in an IPO five years ago and now trades at a 6% discount to its NAV.

Step 1: Identify the defining feature of each fund

Fund A prices once daily and settles at NAV. Fund B trades continuously with a creation/redemption mechanism. Fund C has a fixed share count and a price that differs from NAV.

Step 2: Match each feature to a fund type

Fund A is a mutual fund. Fund B is an ETF. Fund C is a closed-end fund.

The trading and pricing mechanism, not the underlying holdings, tells you what type of pooled vehicle you are looking at. A discount or premium to NAV is a strong signal of a closed-end fund, because only a fixed share count allows that gap to persist.

Common Exam Traps

Treating every pooled vehicle as open-end

Closed-end funds and some other pooled products do not create or redeem shares on demand. Only mutual funds and ETFs are open-end.

Confusing NAV calculation with trading price

NAV is calculated once daily from fund assets and liabilities. Market price is what investors actually pay or receive when trading ETF or closed-end fund shares, and it can differ from NAV.

Assuming ETFs always trade at NAV

The creation/redemption process keeps ETF price close to NAV under normal conditions, but the two are not guaranteed to be identical, especially during volatile markets.

Ignoring fees and liquidity differences

A question may describe a fund's costs or redemption terms to test whether you can identify the vehicle type, not just its returns.

Practice Question

An investor wants to buy shares of a pooled fund that trades continuously during market hours and typically stays close to its net asset value due to an arbitrage mechanism involving authorized participants. Which type of fund best matches this description?

1. Open-end mutual fund

2. Exchange-traded fund

3. Closed-end fund
