Ethics and Trust in the Investment Profession: Chapter Guide
This chapter explains why ethics matters in investing and how you reason through ethical problems. You study professionalism, the link between ethics and healthy capital markets, an ethical decision-making framework, and the Preamble to the CFA Code of Ethics. To solve questions, identify the duty at stake, then pick the option that best serves clients, markets and integrity.
What this chapter covers
This chapter is the foundation of the Ethical and Professional Standards topic. It asks a basic question: why should investors trust the people who manage their money? You learn that a profession is more than a job. It has a body of knowledge, a code of conduct, and a duty to put others' interests first.
The chapter then moves from the individual to the system. Ethical behaviour supports fair, efficient and transparent capital markets. When trust falls, investors demand higher returns or leave, and capital is allocated badly. You also learn the difference between ethical and unethical conduct, and why legal compliance alone is not enough. A framework for ethical decision-making gives you a repeatable way to analyse a dilemma, and the Preamble to the CFA Code of Ethics sets out the purpose of the Code and Standards.
This material connects to the rest of the paper in two ways. First, it prepares you for the Standards of Professional Conduct, where every question is a short case and you must name the right action. Second, the same ideas of fair dealing, transparency and client interest appear in other topics, such as portfolio management, financial reporting quality and market efficiency. Ethics questions are three-option MCQs (A, B, C), like all others.
Ethical and Professional Standards carries one of the highest topic weights at Level I, 10-15% for exams from February 2027, and the questions are very learnable because the logic is consistent. Results are Pass or Did Not Pass with no minimum per topic, but a strong ethics score is one of the most reliable ways to build a buffer toward the 1600 Minimum Passing Score. This chapter gives you the vocabulary and mindset that make the later Standards chapters much easier. Time spent here repays itself in every ethics question you meet.

How to prepare Ethics and Trust in the Investment Profession
This is a concept chapter with little calculation, so you can study it in short sessions, including on your phone during a commute. Aim for understanding, not memorised phrases.
- Read each topic once, slowly, and write one sentence in your own words for the main idea: trust, professionalism, market integrity, decision framework, purpose of the Code.
- Learn the exact steps of the ethical decision-making framework and practise saying them in order without looking.
- Compare ethical conduct with legal conduct. Make a short list of situations that are legal but still unethical, and note why.
- Read the Preamble from the official CFA Institute text and underline the duties it describes, such as placing client and market integrity above personal interest.
- Answer practice MCQs on the chapter. For each, eliminate the two weaker options by asking which one fails to protect clients, markets or integrity.
- Review every wrong answer and note which principle you missed. Repeat the set after a few days.
- Before the exam, revisit this chapter briefly, then move to the Standards of Professional Conduct while the principles are fresh.
Common mistakes in Ethics and Trust in the Investment Profession
Treating the chapter as common sense and skipping practice questions.
Fix: Practise MCQs. The exam rewards the Code's specific view of correct action, which may differ from what you would do at work.
Assuming that if something is legal, it is ethical.
Fix: Remember that the Code can demand more than local law. Ask what best protects clients and market integrity.
Memorising the framework as a list without applying it.
Fix: Take two or three short dilemmas and walk through each step in writing until the process feels natural.
Choosing the answer that protects the employer or oneself.
Fix: Apply the principle that client interests and market integrity come before employer and personal interests.
Paraphrasing the Preamble loosely and missing its exact purpose.
Fix: Read the official text closely once, note its key duties, and revisit it when you begin the Standards.
Last-day revision: Ethics and Trust in the Investment Profession
- A profession has specialised knowledge, a code of conduct and a duty to serve others' interests.
- Trust in investment professionals underpins client relationships and the wider financial system.
- Ethical markets support fair, transparent and efficient allocation of capital.
- Loss of trust raises the cost of capital and discourages participation in markets.
- Legal compliance is the minimum; ethical behaviour often asks for more.
- Ethical conduct is judged by the effect on clients, markets and the profession, not only on the firm.
- The ethical decision-making framework moves you from facts to action: identify the relevant facts, stakeholders, duties and conflicts of interest; consider situational influences and the guidance that applies (the Code and Standards, laws, firm policies); then decide and act on the alternative that best satisfies the ethical principles and the checklist. Check the exact step names against the current curriculum text.
- The Preamble states the purpose of the Code and Standards and the duty to place client and market integrity first.
- Ethics questions are three-option MCQs; pick the action that best upholds the Code and Standards.
- Choose the option that best matches what the Code and Standards require, and eliminate options that fall short.
- No penalty for wrong answers, so never leave an ethics question blank.

Ethics and Trust in the Investment Profession: frequently asked questions
Is Ethics and Trust in the Investment Profession a difficult chapter?
It has no calculations, so it feels easier than most topics. The challenge is applying principles to short cases and avoiding options that sound reasonable but fall short of the Code. Regular practice fixes this.
How much time should I give this chapter?
It is a short, foundational chapter, so it needs less time than the Standards chapters that follow. Study it early, then revisit it briefly before the exam. Spend more of your ethics time on applying the Standards.
Do I need to memorise the Code of Ethics word for word?
You do not need to recite it, but you should know its main duties and be able to recognise them in a case. For the Standards, know the official names and the key requirements, because questions refer to them directly.
How is this chapter tested in the exam?
It is tested through three-option MCQs (A, B, C), like the rest of the Level I exam. Expect short scenarios asking which action or view is most consistent with ethical conduct and the Code. All questions are equally weighted and there is no penalty for wrong answers.
