10 Common CFA Ethics Mistakes Candidates Make (and How to Avoid Them)

Most candidates do not lose ethics marks because they lack integrity. They lose them because of predictable CFA ethics mistakes: reading too fast, relying on gut feeling, or misunderstanding how a Standard actually works. Here are ten of the most common errors, with short fictional examples and a fix for each.

Mistake 1: Assuming Local Law Always Wins

Many candidates think that if something is legal where they work, it is acceptable under the Code. That is not how Standard I(A), Knowledge of the Law, works. Members and candidates must follow the stricter of applicable law or the Code and Standards. If local rules allow something the Standards prohibit, the Standards apply. If local law is stricter, follow the law.

Example: Neha works for a fictional firm, Coral Bay Securities, in a country where trading on certain inside information is not clearly illegal. She still cannot act on material nonpublic information, because the Standards forbid it.

Fix: In every scenario, ask which rule is stricter, then follow that one. Also remember that if you know of a violation by others, you should dissociate from it, which may include reporting to compliance or declining to continue the work.

Mistake 2: Confusing Duty to the Employer with Duty to Clients

Standard IV(A) requires loyalty to your employer, and Standard III(A) requires loyalty to clients. When they conflict, the client's interests come first, and duties to the employer never require you to break the Code or harm clients.

Example: Vikram's manager at Harbour Point Asset Management tells him to push an expensive in-house fund on all retail clients, regardless of suitability. Obeying would favour the employer over clients and breach suitability.

Fix: Remember the general priority order: clients, then employer, then yourself. Also note that loyalty to the employer covers things like not taking client lists or confidential files when you leave, and not competing with your employer while still employed.

Mistake 3: Mixing Up the Mosaic Theory and Material Nonpublic Information

The mosaic theory lets an analyst combine public information with non-material nonpublic information to reach a conclusion that is itself material, without violating Standard II(A). Candidates often go wrong in one of two ways: they treat any private conversation as forbidden, or they assume that any analysis is protected by the mosaic theory, even when one piece is both material and nonpublic.

Example: Ananya, a fictional analyst, combines factory-gate traffic observations, public shipping data and a general comment from an investor relations officer. That is a legitimate mosaic. If the CFO had told her quarterly earnings early, the analysis would include MNPI and could not be acted on.

Fix: Test each piece of information separately: is it material, and is it nonpublic? If any single piece is both, the mosaic defence fails. Our article on mosaic theory and material nonpublic information covers this in depth.

Mistake 4: Misusing the CFA Designation

Standard VII(B) controls how you refer to CFA Institute, the designation and the Program. Common errors include:

• Using "CFA" as a noun ("she is a CFA") instead of an adjective ("she is a CFA charterholder").
• Implying a partial designation, such as writing "CFA Level II" after your name.
• Suggesting that charterholders achieve better investment results.
• Continuing to use the designation after membership lapses.

It is acceptable to state facts, for example that you passed all three levels on your first attempts or that you are a Level II candidate in the CFA Program.

Fix: Accurate facts are allowed; exaggerated claims and implied superiority are not.

Mistake 5: Ignoring the "Most Appropriate" Wording

Ethics questions often ask what is most appropriate, or which action is least likely to violate the Standards. Several options may be partly acceptable. Candidates who pick the first reasonable choice lose marks.

Fix: Read all options before choosing. Rank them. The best answer is usually the one that protects clients fully, includes appropriate disclosure, and does not go beyond what the Standards actually require. Watch for absolute words such as "always" and "never" in the options.

Mistake 6: Thinking Disclosure Fixes Everything

Disclosure is powerful under the Standards, especially for conflicts of interest and additional compensation. But it does not cure every problem. You cannot disclose your way out of front-running, trading on MNPI, misrepresenting performance or buying unsuitable investments.

Example: Sameer tells clients that he trades personally in the same stocks he recommends. That disclosure is good, but it does not permit him to trade before his clients.

Fix: Ask whether the action itself harms clients or markets. If it does, disclosure is not enough.

Mistake 7: Overlooking Gifts and Additional Compensation Rules

Candidates often confuse two related ideas. Under Standard I(B), Independence and Objectivity, modest gifts are generally acceptable, but gifts that could compromise objectivity are not. Gifts from clients are viewed differently from gifts from third parties trying to win business. Under Standard IV(B), Additional Compensation Arrangements, any compensation from a client that depends on future performance and might conflict with the employer's interests needs written consent from the employer before you accept it.

Fix: Identify who is giving the benefit and why. Performance-linked rewards from clients need employer consent; lavish third-party gifts tied to business decisions should be declined.

Mistake 8: Treating Fair Dealing as Equal Treatment

Standard III(B) requires fair dealing, not identical service. Firms may offer premium service levels, provided they are disclosed and do not disadvantage other clients. What is prohibited is hidden favouritism, such as giving new recommendations to selected clients first or allocating hot IPO shares only to big accounts.

Fix: Ask whether some clients gained at others' expense without disclosure. For portfolio managers, this connects closely to trade allocation, explained in our post on CFA Level 3 ethics for portfolio managers.

Mistake 9: Forgetting About Supervisors' Responsibilities

Under Standard IV(C), anyone with supervisory authority must make reasonable efforts to prevent and detect violations by those they supervise, whether or not the supervised people are CFA Institute members. Candidates often assume a supervisor is fine as long as they personally behaved well.

Example: Lakshmi, head of research at Bluewater Advisors, learns that an analyst may be trading ahead of his own reports. If she only reminds him of the policy and does nothing else, she has not met her duty. She should investigate promptly and may need to limit his activities while the review takes place.

Fix: If the person in the question supervises others, ask whether adequate procedures exist and whether they acted on warning signs.

Mistake 10: Under-preparing Because Ethics "Feels Easy"

The biggest mistake is strategic. Ethics questions use everyday language, so candidates assume common sense is enough and focus on quantitative topics instead. In reality, ethics is full of precise distinctions: the difference between "material" and "nonpublic", between a client and a sponsor, between record retention and confidentiality.

Fix: Schedule regular ethics practice from the start, and review the reasoning behind every answer. Our tips for passing CFA ethics explain how to build that habit.

Frequently Asked Questions

What is the most common CFA ethics mistake?

Choosing an answer that is acceptable but not the most appropriate. Reading every option carefully and ranking them prevents many lost marks.

Does the stricter-rule principle apply to Indian candidates?

Yes. Wherever you work, you follow the stricter of applicable law (such as SEBI regulations) or the Code and Standards.

Can I write "CFA Level 1 passed" on my CV?

You may state facts accurately, for example that you passed Level I of the CFA Program. You must not imply a partial designation or use "CFA" as if you already hold the charter.

How can I avoid ethics mistakes on exam day?

Practise regularly with timed questions, keep an error log of the traps you fall for, and review the reasoning behind every answer, not just your score.
