Updated for the 2026-2027 CFA® Level I curriculum.
An analyst's estimate of value only means something when it is compared to market price. That comparison is the entire point of this LOS. Once you can estimate a security's value, Level I expects you to state a clear conclusion: is it overvalued, fairly valued, or undervalued? This note shows exactly how to make that call and how to talk about it correctly on exam day.
Quick Answer
A security is overvalued when market price is greater than estimated value, undervalued when market price is less than estimated value, and fairly valued when the two are equal. The classification depends entirely on the analyst's estimate. If the estimate changes, the conclusion can change too.
Level I tests whether you can apply this comparison correctly and explain that the conclusion is conditional, not absolute.
Key Takeaways About Overvalued, Fairly Valued, and Undervalued Securities
Estimated value is the analyst's calculated view of what a security is worth. Market price is what the security actually trades for.
Market price greater than estimated value means the security is overvalued.
Market price less than estimated value means the security is undervalued.
Market price equal to estimated value means the security is fairly valued.
The conclusion is conditional on the estimate. A different model, input, or assumption can produce a different classification.
Valuation involves uncertainty. Analysts should treat conclusions as probable, not guaranteed.
This comparison is a decision rule, not a valuation model. The model produces the estimate. This LOS asks what to do with it.
What You Need to Know for CFA Level I
Know the direction of each comparison: which side of the inequality means overvalued versus undervalued.
Be able to classify a security correctly from a stated market price and estimated value.
Understand that the classification is a conclusion drawn from an estimate, not an objective fact.
Recognize that changing the estimate can flip the classification even if market price stays the same.
Understand why uncertainty in the estimate affects how confidently an analyst can act on the conclusion.
Avoid confusing this comparison with the mechanics of any single valuation model.
Estimated Value Versus Current Market Price
Market price is observable. It is the price at which a security last traded or currently trades in the market. Estimated value is not observable. It is the analyst's calculated view of what the security is worth, based on a chosen valuation model and a set of inputs.
These two numbers answer different questions. Market price reflects what the market currently believes, aggregated across all buyers and sellers. Estimated value reflects what one analyst believes, based on a specific set of assumptions about cash flows, growth, risk, and discount rates.
The comparison between the two is only useful if the estimate is reasonable. A poorly built estimate produces a comparison that looks precise but means little. Level I does not test you on building a full valuation model in this LOS. It tests you on what to do once you have an estimate.
Conditions for Classifying a Security
Once you have an estimated value, the classification rule is simple. It has three possible outcomes.
Condition | Classification | What It Suggests |
|---|---|---|
Overvalued | The security may be priced too high relative to the analyst's estimate | |
Undervalued | The security may be priced too low relative to the analyst's estimate | |
Fairly valued | The market price matches the analyst's estimate |
Notation:
Market price () is the current traded price of the security.
Estimated value () is the analyst's calculated value based on a chosen model.
Compare market price with estimated intrinsic value : implies overvalued, implies undervalued, and implies fairly valued.
A common way candidates lose points here is reversing the inequality. Read the comparison slowly. A high market price relative to the estimate does not mean the security is a good deal. It means the market is charging more than the analyst thinks it is worth.
How the Conclusion Changes When the Estimate Changes
The classification is not a fixed property of the security. It is a conclusion drawn from one analyst's estimate at one point in time. Change the estimate, and the conclusion can change, even though market price has not moved at all.
This happens for several reasons:
A different valuation model can produce a different estimate.
Different assumptions about growth rates or discount rates change the estimate even within the same model.
New information about the company can shift the estimate up or down.
Two analysts using reasonable but different inputs can reach different conclusions about the same security on the same day.
This is why Level I frames the LOS as a comparison, not a fact. The exam wants you to understand that "overvalued" is shorthand for "overvalued according to this estimate," not an unconditional statement about the security.
Why Valuation Uncertainty Matters to Interpretation
Every estimated value carries uncertainty. It depends on forecasted cash flows, assumed growth rates, and a discount rate that reflects estimated risk. None of these inputs are known with certainty. Small changes in any one of them can move the estimate enough to change the classification.
Treat Valuation as a Range, Not a Precise Figure
Because of this, a single point estimate should be treated as one plausible outcome, not a precise, guaranteed figure. Analysts often build a range of estimates using different assumptions to see how sensitive the conclusion is.
If a security is classified as undervalued under most reasonable assumptions, the analyst has more confidence in that conclusion. If the classification flips easily with small changes, the analyst should treat the conclusion cautiously.
Focus on Interpretation for Level I
For Level I, the key point is conceptual. You are not expected to run a full sensitivity analysis. You are expected to recognize that the estimate is not certain and that this uncertainty is a normal part of interpreting the comparison, not a flaw in the process.
Worked Example
An analyst covers three companies and estimates each one's value using a chosen valuation model. Market prices are current as of the same trading day.
Case 1: Harborview Foods
Market price: $42 per share
Estimated value: $50 per share
Comparison: Market price is less than estimated value.
Classification: Undervalued.
Case 2: Prairie Rail Corp
Market price: $118 per share
Estimated value: $101 per share
Comparison: Market price is greater than estimated value.
Classification: Overvalued.
Case 3: Alden Instruments
Market price: $76 per share
Estimated value: $76 per share
Comparison: Market price equals estimated value.
Classification: Fairly valued.
Harborview looks like a potential opportunity if the $50 estimate is reasonable, since the market is charging less than the analyst believes it is worth.
Prairie Rail looks expensive relative to the analyst's estimate. Alden shows no gap between price and estimate.
All three conclusions depend on the estimate. If the analyst revised Prairie Rail's estimated value up to $125, the same market price of $118 would now make it undervalued instead of overvalued. The market price never moved. Only the conclusion did.
Common Exam Traps
Reversing the inequality
Candidates sometimes classify a security as undervalued when market price exceeds estimated value, or the reverse. Slow down and confirm which number is larger before concluding.
Treating the estimate as fact
The exam sometimes phrases a question to test whether you understand that "undervalued" depends on the analyst's model and inputs. Do not treat the estimate as an objective truth about the security.
Calling a security undervalued when market price exceeds estimated value
This is the reverse of the correct rule. Undervalued means the market price is below the estimate, not above it.
Bringing in unrelated valuation methods
This LOS tests the comparison and classification, not how to build a dividend discount model or a multiples-based estimate. Do not spend exam time recalculating a model when the question only asks for the classification.
Practice Question
An analyst estimates the value of Colton Beverage Company at $64 per share using a valuation model. The stock currently trades at $59 per share. Based on this information, how should the analyst classify the security?
Overvalued, because market price is below the analyst's estimate
Undervalued, because market price is below the analyst's estimate
Fairly valued, because the difference between price and estimate is small
Correct Answer: B
Market price is $59 and estimated value is $64. Since market price is less than estimated value, the security is undervalued according to the rule: means undervalued.
Option A: This reverses the classification rule. A market price below the estimate does not mean overvalued. It means undervalued.
Option C: A price difference of $5 is not equal to zero, so the security is not fairly valued. Fairly valued requires market price and estimated value to match, not merely be close.

FAQs About Overvalued, Fairly Valued, and Undervalued Securities
Is a security automatically a buy if it is undervalued?
Not automatically. Undervalued means market price is below the analyst's estimate. Whether to act on that conclusion depends on confidence in the estimate, transaction costs, and other portfolio considerations outside this LOS.
Can two analysts reach different conclusions about the same stock on the same day?
Yes. Since each analyst's estimated value depends on their own model and assumptions, different analysts can classify the same security differently even when market price is identical for both.
Does "fairly valued" mean the estimate is correct?
No. It means the analyst's estimate happens to match the current market price. The estimate could still be wrong. Fairly valued is a statement about the comparison, not proof of accuracy.
