Updated for the 2026-2027 CFA® Level I curriculum.
Every portfolio is built from a small set of major asset classes, each with its own risk, return, and liquidity profile. CFA Level I tests whether candidates can identify these characteristics and explain why they matter, not just recall definitions.
This note compares cash and cash equivalents, fixed income, equity, real estate, commodities, and alternative investments so you can answer classification and comparison questions with confidence.
Quick Answer
Major asset class characteristics describe how each asset class behaves in terms of expected return, volatility, liquidity, income, and sensitivity to inflation. An equity portfolio, for example, offers higher expected return and capital growth but carries more volatility and less predictable income than a fixed income portfolio.
CFA Level I tests these characteristics so candidates can match an asset class to an investor's goals, without confusing characteristics with the allocation decision itself.
Key Takeaways About Major Asset Class Characteristics
Six major asset classes appear on the exam: cash and cash equivalents, fixed income, equity, real estate, commodities, and alternative investments.
Each asset class has a distinct combination of expected return, volatility, liquidity, income, and inflation sensitivity.
An equity portfolio generally offers the highest long-term return potential among traditional asset classes, paired with the highest volatility.
Real assets, such as real estate and commodities, tend to respond differently to inflation than financial assets like stocks and bonds.
Alternative investments are not one uniform category. Liquidity and risk vary widely within this group.
Describing asset-class characteristics is different from deciding how much of each to hold. The exam tests both skills separately.
What You Need to Know for CFA Level I
Identify each major asset class by its defining features, not by a specific security name.
Compare asset classes on five dimensions: return drivers, risk, liquidity, income, and inflation sensitivity.
Recognize that an equity portfolio's return comes mainly from price appreciation and dividends, while a bond's return comes mainly from coupon income.
Understand that liquidity varies sharply across asset classes, from highly liquid cash to illiquid private real estate or private equity.
Know that alternative investments include hedge funds, private equity, private debt, and real assets, each with different risk and liquidity traits.
Separate asset-class characteristics (what an asset class is like) from asset allocation (how much of it to hold in a portfolio).
The Six Major Asset Classes
Cash and Cash Equivalents
Cash and cash equivalents include bank deposits, Treasury bills, and money market instruments. These assets have very low risk, high liquidity, and low expected return. They preserve capital rather than grow it. Investors use cash to meet short-term obligations and to hold dry powder for opportunities.
Fixed Income
Fixed income securities, such as government and corporate bonds, promise a stream of interest payments and return of principal at maturity. Risk depends on credit quality, interest rate exposure, and maturity. Fixed income generally has lower expected return than equity but provides more predictable income and lower volatility.
Equity
Equity represents ownership in a company. An equity portfolio holds common shares selected for growth, income, or a combination of both. What is an equity portfolio, in practical terms? It is a collection of stocks chosen to give an investor exposure to corporate profits and price growth. Equities in a portfolio provide the highest expected long-term return among traditional asset classes, along with the highest volatility. Return comes from capital appreciation and, in many cases, dividend income.
Real Estate
Real estate includes direct property ownership and securitized vehicles such as REITs. It offers income through rents, potential appreciation, and some inflation protection, since rents and property values often adjust with price levels. Direct real estate is illiquid. Publicly traded REITs are more liquid but still carry equity-like volatility.
Commodities
Commodities include energy, metals, and agricultural products. They generate no income on their own. Returns come from price changes, often influenced by supply, demand, and inflation expectations. Commodities can hedge inflation risk but tend to be volatile and cyclical.
Alternative Investments
Alternative investments include hedge funds, private equity, private debt, and infrastructure. This category is not uniform. Some alternatives use leverage and complex strategies. Others hold illiquid private assets with long lockup periods. Risk, liquidity, and return drivers vary by strategy, so candidates should avoid treating all alternatives as one risk profile.
Comparing Asset Classes by Risk, Return, Liquidity, Income, and Inflation Sensitivity
The table below summarizes how each major asset class behaves across the five dimensions the exam tests most often.
Asset Class | Expected Return | Volatility | Liquidity | Income | Inflation Sensitivity | Typical Portfolio Role |
|---|---|---|---|---|---|---|
Cash and cash equivalents | Low | Very low | Very high | Low | Low | Capital preservation, liquidity buffer |
Fixed income | Low to moderate | Low to moderate | Moderate to high | Moderate to high | Moderate | Income, diversification |
Equity | High | High | High (public markets) | Low to moderate | Moderate | Growth, capital appreciation |
Real estate | Moderate to high | Moderate | Low (direct) / moderate (REITs) | Moderate to high | Moderate to high | Income, diversification, inflation hedge |
Commodities | Variable | High | Moderate | None | High | Inflation hedge, diversification |
Alternative investments | Variable | Variable | Low | Variable | Variable | Diversification, return enhancement |
How Asset Class Characteristics Shape Portfolio Role
Each asset class earns a place in a portfolio because of what it contributes, not just what it returns. Cash provides liquidity for near-term needs. Fixed income supplies steady income and dampens volatility. An equity portfolio drives long-term growth. Real estate and commodities add diversification and can help offset inflation. Alternative investments can enhance return or reduce correlation with traditional assets, depending on the strategy.
Candidates should connect each characteristic to its role. A question that describes low liquidity, no income, and high inflation sensitivity is describing commodities, not fixed income. A question describing high expected return, high volatility, and dividend potential is describing equity.
Distinguishing Asset-Class Characteristics From an Allocation Decision
Describing an asset class is not the same as deciding how much of it to hold. Characteristics are fixed traits: equity is more volatile than fixed income, and cash is more liquid than real estate. Allocation is a choice: how much cash, equity, or real estate an investor should hold given goals, constraints, and risk tolerance.
CFA Level I tests characteristics in this reading. Later material tests allocation decisions using these characteristics as inputs. If a question asks you to identify a trait, you are in characteristics territory. If it asks you to recommend a weight or a mix, that is an allocation question.
Worked Example: Matching Investor Needs to Asset Class Characteristics
Scenario: An advisor is reviewing three investor profiles.
Investor A needs to fund a home down payment in four months and cannot accept any loss of principal.
Investor B wants steady income for the next ten years and can tolerate moderate price swings.
Investor C worries about rising inflation eroding purchasing power over the next five years and has no immediate liquidity needs.
Step 1: Match Investor A to an asset class.
Investor A needs high liquidity and capital preservation in the short term. Cash and cash equivalents fit best. Equity or real estate would expose the investor to unacceptable short-term price risk.
Step 2: Match Investor B to an asset class.
Investor B wants predictable income with moderate risk tolerance. Fixed income fits best. It provides scheduled coupon payments and lower volatility than equity or commodities.
Step 3: Match Investor C to an asset class.
Investor C is most concerned with inflation protection and does not need liquidity soon. Real estate or commodities fit better than cash or fixed income, since both have historically shown stronger inflation sensitivity in the same direction as rising prices.
Each investor's need points to a different asset class because each asset class carries a different combination of liquidity, income, and inflation sensitivity. The advisor matched needs to characteristics first, before deciding on specific weights.
Common Exam Traps
Treating all alternatives as one risk profile
Hedge funds, private equity, and private debt have different liquidity, leverage, and return drivers. Do not assume every alternative investment is high risk and illiquid.
Confusing an asset class with a specific security
An asset class is a category, such as equity. A specific stock or bond is one security within that category. Exam questions test the category-level characteristics.
Assuming a higher historical return always makes an asset class suitable
A high average return does not override an investor's liquidity needs or risk tolerance. Suitability depends on the full characteristic profile, not return alone.
Drifting into allocation instead of describing characteristics
If a question asks about the traits of an asset class, do not answer with a recommended percentage weight. Save allocation reasoning for allocation questions.
Practice Question
An investor holds a diversified equity portfolio and is concerned about maintaining purchasing power if inflation rises unexpectedly over the next three years. The investor does not need to sell any holdings during this period. Which asset class is most likely to address this concern, based on its typical characteristics?
Cash and cash equivalents
Commodities
Fixed income (long-term government bonds)
Correct Answer: B
Commodities typically show a stronger positive relationship with unexpected inflation than cash or long-term fixed income. Prices for energy, metals, and agricultural products often rise alongside general price levels, which helps offset the erosion of purchasing power.
Option A: Cash and cash equivalents preserve nominal value but offer little protection against inflation, since their real value falls as prices rise.
Option C: Long-term fixed income is often more vulnerable to unexpected inflation, since fixed coupon payments lose purchasing power and rising rates can reduce bond prices.

FAQs About Major Asset Class Characteristics
What is an equity portfolio?
An equity portfolio is a collection of stocks selected to give an investor exposure to corporate ownership. Returns come from price appreciation and, in many cases, dividends.
What are equities in a portfolio?
Equities in a portfolio are the common shares held to pursue growth. They typically carry higher expected return and higher volatility than fixed income or cash holdings.
Why does fixed income have lower volatility than equity?
Fixed income pays a scheduled coupon and returns principal at maturity, which makes cash flows more predictable. Equity returns depend on variable profits and market sentiment, which increases price swings.
Do all alternative investments have low liquidity?
No. Liquidity varies by strategy. Some hedge fund strategies allow periodic redemptions, while private equity and private debt often lock up capital for years.
