CFA Level 1 · Module 01 Ethical and Professional Standards · Chapter 4
Standard I protected the professional’s own integrity. Standard II protects something larger: the integrity of the market itself. A market works only if participants believe prices are set fairly and that no one is trading on secrets the rest of the market cannot see, or bending prices to deceive. When that belief breaks, investors demand a higher return to take part or leave altogether, and the whole system becomes more expensive and less useful. Standard II exists to keep that belief intact.
The Standard has two sub-sections. II(A) Material Nonpublic Information governs what you may do with information that is both price-moving and not yet available to the market. II(B) Market Manipulation prohibits deceiving other participants by distorting prices or trading volume. This reading works through both, along with two ideas that candidates must hold precisely: the mosaic theory, which tells you what analysts may do, and the firewall, which is the main procedure for keeping sensitive information from being misused.
As throughout the Ethics module, MidhaFin teaches the duties in its own words and illustrates them with invented scenarios. No example, company, or number below is taken from the source curriculum or any prep provider.
Trading on secret information or faking market activity is not just unfair to the person on the other side of a single trade. It corrodes the confidence that lets strangers transact at all. If investors suspect that insiders always win and that prices can be pushed around, they price that risk into every decision, demanding higher returns and participating less. The result is a market that raises capital less efficiently, which ultimately harms the companies that need funding and the society that benefits from productive investment.
The mechanism is worth spelling out because it explains why the profession treats these breaches so seriously. When an ordinary investor believes some counterparties trade on secrets they cannot see, every quote becomes suspect: the investor cannot tell whether the person selling to them knows something they do not. To compensate for that risk, investors widen the spreads they are willing to accept and demand a higher expected return before committing capital. A higher required return is simply a higher cost of capital for issuers, which means fewer projects funded, less innovation, and slower growth. Manipulation does the same damage from a different angle, by making prices lie about real supply and demand so that capital is allocated on false signals. Standard II protects the informational fairness that keeps that whole machine running.
That is why Standard II frames these duties around the market as a whole rather than around any one client. A violation of II(A) or II(B) can leave your own clients unharmed and still be a serious breach, because the victim is the fairness of the market and the trust of everyone who relies on it. Keep that lens in mind: when a scenario asks whether conduct is acceptable, the test is whether it undermines the level playing field that market integrity depends on.
It is also worth seeing how Standard II sits alongside the law. Most jurisdictions prohibit insider trading and market manipulation through statute and regulation, and Standard I(A) already requires you to obey those laws. Standard II adds an ethical duty that stands on its own: even where a local law is weak, poorly enforced, or silent on a particular practice, the Standard still binds you. So a member cannot defend trading on inside information by pointing out that the local regulator rarely prosecutes it, and cannot defend a manipulative scheme by noting that no specific rule names it. The ethical obligation to preserve market integrity is independent of, and often broader than, the legal one.
Members and Candidates who possess material nonpublic information that could affect the value of an investment must not act or cause others to act on the information.
Verbatim wording of the Standard as published by CFA Institute; all explanation and examples below are MidhaFin’s own.
Standard II(A) states that anyone who possesses material nonpublic information that could affect an investment’s value must not act on it, or cause others to act on it. The rule reaches beyond individual stocks to bonds, derivatives, funds, and other instruments, and it applies however you obtained the information, whether you sought it, stumbled on it, or were handed it. Two words do the work: material and nonpublic.
Material information is information that would likely affect a security’s price, or that a reasonable investor would want to know before making an investment decision. Materiality is a matter of degree and depends on the facts. The reliability of the source matters: a firm fact from a corporate insider about a major new contract is likely material, while a distant rumour or a broad assumption is not. The clarity of the effect matters too: if it is unclear whether or how information would move a price, it may not be material. And time matters, because information that was once price-moving can become immaterial once it is stale or once events overtake it.
Nonpublic information is information that has not yet been disseminated to the marketplace in general. Once information is released so that investors at large have access to it, it is public and may be acted on. Information shared with only a few analysts, or disclosed on a limited basis, remains nonpublic, and trading on it can be an insider-trading violation. The key is availability to the whole market, not merely that a handful of people happen to know it. Note the practical corollary: you must give information time to be absorbed. Trading in the instant after a release, before the market has actually had a chance to receive and react to it, can still be trading ahead of the public.
It helps to have a sense of the kinds of facts that are typically material. Impending mergers, acquisitions, or tender offers are almost always material, as are significant earnings surprises, changes to dividend policy, major new products or contracts, the gain or loss of a significant customer, important litigation or regulatory action, a pending change in senior management or auditor, and planned issues or buybacks of securities. None of these is automatically material in every case, materiality always turns on the facts, but they are the categories that most often move prices, and a scenario built around any of them should put you on alert. Conversely, broad opinions, well-known trends, and information already reflected in the price are unlikely to be material.
| Factor | More likely material | Less likely material |
|---|---|---|
| Source reliability | Firm fact from a corporate insider | Vague rumour or distant hearsay |
| Effect on price | Clear, significant likely impact | Ambiguous or negligible impact |
| Specificity | Concrete detail (a signed contract, exact earnings) | General conjecture or opinion |
| Timing | Current and not yet reflected in price | Stale, or already overtaken by events |
Setup. Arjun, a fund manager at the fictional Vindhya Asset Management, is seated next to a lawyer on a flight who, believing the conversation private, describes an unannounced takeover of a listed company his firm is finalizing. Arjun realizes he could buy the target before the news breaks.
Answer: buying the target would violate Standard II(A). Overhearing the information by accident does not create a right to use it; he must refrain from trading and from passing it on.
Standard II(A) has two prohibited actions, not one: you must not act on material nonpublic information, and you must not cause others to act on it. Tipping a friend, a colleague, or a client is a violation even if you never trade yourself. And the source is irrelevant, whether the information came from an insider, an overheard conversation, a misdirected email, or a selective disclosure, possession is what triggers the duty to refrain.
What, then, should you actually do when you find yourself holding material nonpublic information? You refrain from trading in the affected security for yourself, for clients, and for your firm, and you refrain from recommending it. You do not pass the information on. And you follow your firm’s procedures, typically alerting compliance so the security can be placed on a restricted list until the information is public or no longer material. Doing nothing quietly is not the same as handling it correctly; the information needs to be contained, not just left unused by you.
Setup. Kavya, an analyst at the fictional Godavari Securities, is told directly by a listed company’s finance head, before any announcement, that a large government order has just been cancelled and that profit will fall sharply. She reasons that she had already flagged the risk from public tender records, so she sells the position for her clients.
Answer: Kavya would violate Standard II(A). Receiving the material fact directly is not a mosaic; possession of the confirmed nonpublic fact bars her from acting on it.
Standard II(A) does not stop analysts from doing their job. The mosaic theory recognizes that a skilled analyst can combine pieces of information, public information together with non-material nonpublic information, into a conclusion that is itself material, and may then act on that conclusion. The point is subtle but essential: a conclusion an analyst reaches by assembling many small, individually non-material pieces is the product of analysis, not a leaked secret, even if the same conclusion would have been material inside information had a company simply handed it over.
The distinction is between receiving a material fact and constructing a material insight. If a company tells you directly that earnings will miss, that is material nonpublic information and you cannot trade. If instead you notice reduced shipping activity, a supplier’s cautious comments, and weak sector data, and you infer that earnings will disappoint, you have built a mosaic and may act on your own analysis. This is the engine of legitimate research, and it is why diligent analysts add value.
Understanding the mosaic theory also explains why skilled analysis is valuable and legitimate rather than suspect. Markets become efficient precisely because analysts dig up scattered, individually harmless facts and reason their way to conclusions ahead of the crowd; that work is what pushes prices toward reflecting reality. Penalizing an analyst for reaching a material conclusion through diligence would discourage exactly the activity that makes markets informative. The Standard therefore draws the line at the input, not the output: a material fact received is off limits, a material conclusion constructed is the reward for good work.
Because the line can look thin from the outside, analysts who rely on the mosaic theory should document their research: keep the public and non-material sources that led to the conclusion, so that a well-founded analytical judgment cannot be mistaken for trading on a tip. Good records are the analyst’s protection, and they matter most exactly when a conclusion turns out to be strikingly accurate, because that is when an outside observer is most tempted to assume a leak.
The mosaic theory is the most tested idea in Standard II. The trigger for a violation is possessing a material fact that is nonpublic, not reaching a material conclusion by analysis. If a scenario shows an analyst assembling public and non-material pieces into an insight, that is compliant, and thorough documentation is what proves it. If a scenario shows an analyst simply handed a material secret, no amount of surrounding analysis makes trading acceptable.
A related hazard is selective disclosure: a company insider giving material information to a favoured few, such as select analysts, before releasing it to the market. An analyst who receives material information this way is in possession of material nonpublic information and must not trade on it, even though they did not seek to cheat; the information is still nonpublic. Members should also be alert to the risk that they are being selectively fed material information and handle it accordingly.
The reason selective disclosure is so dangerous is that it can turn an innocent recipient into a rule-breaker without any wrongdoing on their part. You need not have coaxed the information out of anyone; simply being on the receiving end of a favoured leak places you in possession, and possession is the trigger. This is also why passing such information along is treated seriously: the person who relays a material secret spreads the unfair advantage, and the person who trades on a relayed secret is acting on material nonpublic information just the same. The chain does not launder the information clean. Everyone who knowingly touches it is bound to refrain until it is public.
The cure for selective disclosure, from the company’s side, is broad, simultaneous dissemination: releasing material information to the whole market at once rather than to favoured recipients first. From the member’s side, the duty is to recognize when they have been placed in possession of something the market does not have, and to refrain until it is public. A member who realizes an insider is selectively feeding them material information should also consider encouraging the issuer to disclose it publicly, and must not trade in the meantime.
The same caution applies to industry-expert networks, services that connect investors with specialists for insight. Consulting experts is legitimate and can be part of building a mosaic, but if an expert conveys material nonpublic information, for example a consultant who is also an insider at a company under discussion, the member is prohibited from trading on it just as with any other source. Firms that use such networks often require agreements about not disclosing confidential information, but the agreement does not cure the problem: if material nonpublic information is received, it cannot be used. The safeguard reduces the chance of receiving a secret; it does not license acting on one that slips through.
The central recommended procedure under II(A) is the information barrier, usually called a firewall: a set of controls that stops material nonpublic information from moving between parts of a firm that should not share it, most classically between an investment-banking side that learns confidential deal information and a research or brokerage side that trades and advises. An effective firewall keeps employees on only one side of a sensitive matter at a time and controls how, and whether, information may cross.
Alongside the firewall, firms are advised to review employee and proprietary trading, to heighten scrutiny or restrict the firm’s own trading while it holds sensitive information (for example while advising on a pending deal), and to maintain watch and restricted lists of securities about which the firm may have material nonpublic information. Where someone behind a firewall genuinely needs to bring a counterpart across it, that crossing should run through a controlled process, typically compliance, rather than an informal chat. The aim is a reporting system that lets the firm function without letting secrets leak into trading.
A firewall works only if a few conditions hold. Employees should sit on just one side of a sensitive matter at a time, so that no single person is both learning confidential deal information and trading or advising on the affected security. Access to information should be limited to those who genuinely need it. And the firm should keep a record of who was brought over the wall and when, so that if a question of misuse arises later, the movement of information can be reconstructed. These controls are not a formality; without them, ordinary contact between colleagues quietly becomes a channel for inside information to reach the trading desk.
| Procedure | What it does |
|---|---|
| Firewall / information barrier | Blocks material nonpublic information from crossing between conflicted parts of the firm |
| Restrict proprietary trading | Heightens review or halts firm trading in securities about which it holds sensitive information |
| Personal-trading review | Monitors employee trades for possible misuse of inside information |
| Watch and restricted lists | Flags securities where the firm may possess material nonpublic information |
| Controlled crossing process | Routes any needed sharing across a firewall through compliance |
Setup. Sneha, an analyst at the fictional Chambal Research, pieces together a picture of a retailer’s weak quarter from public foot-traffic data, a logistics firm’s comments about lighter volumes, and a competitor’s soft results. She concludes earnings will disappoint and recommends reducing the position, documenting each source.
Answer: Sneha complies with Standard II(A). Building a material insight from public and non-material pieces is legitimate research, and her records are exactly the recommended safeguard.
Setup. Ravi works on the investment-banking side of the fictional Kaveri Financial, where his team is advising on a confidential acquisition. Over lunch he mentions the pending deal loosely to a friend on the firm’s research desk who happens to cover the target company.
Answer: Ravi breaches the firewall and violates Standard II(A). Sensitive deal information must not cross to the research side except through a controlled, documented channel.
Members and Candidates must not engage in practices that distort prices or artificially inflate trading volume with the intent to mislead market participants.
Verbatim wording of the Standard as published by CFA Institute; all explanation and examples below are MidhaFin’s own.
Standard II(B) prohibits practices that distort prices or artificially inflate trading volume with the intent to mislead market participants. Manipulation deceives the people who rely on market signals, and it damages every investor by disrupting the honest functioning of the market and lowering confidence. It comes in two broad forms.
Information-based manipulation works by feeding false or misleading information into the market. The classic example is a pump and dump: spreading overly optimistic or untrue information to inflate a security’s price, then selling into the artificial demand once other participants have pushed the price up. Spreading false rumours to induce others to trade is the same offence in a simpler form.
Transaction-based manipulation works through the trades themselves. It includes entering transactions that create a false impression of activity or price movement, such as trades that change no real ownership (wash trades) or coordinated orders designed to paint a misleading picture, and it includes securing a dominant or controlling position in an instrument in order to exploit and distort the price of that instrument or a related derivative. In each case the member knows, or should know, that the action could distort the price.
The reach of Standard II(B) is deliberately broad because technology keeps creating new avenues. Cornering, taking a dominant position in an underlying asset in order to squeeze the price of a related derivative, is an old technique; entering and rapidly cancelling orders to nudge a quoted price, or splitting activity across venues to hide it, are newer ones. What unites them is that the conduct is designed to make the market show something other than genuine supply and demand. The Standard does not require that anyone actually be fooled or that the scheme succeed; the attempt to distort with intent to mislead is itself the violation.
| Form | How it works | Example |
|---|---|---|
| Information-based | False or misleading information moves the price | Pump and dump; spreading false rumours |
| Transaction-based | Trades themselves distort price or volume | Wash trades; fictitious activity; cornering to exploit a derivative |
Setup. Dev, a trader at the fictional Betwa Capital, holds a large position in a thinly traded small-cap. He posts a series of glowing, exaggerated claims about an imminent contract that he knows is unlikely, watches retail buyers pile in, and sells his holding into the surge.
Answer: Dev violates Standard II(B). Creating an artificial price with misleading information and then selling into it is textbook information-based manipulation.
Setup. Meera, a trader at the fictional Sabarmati Commodities, quietly buys up most of the deliverable supply of a physical commodity ahead of a futures contract’s settlement, so that holders who must take delivery that month are forced to buy from her at prices she can dictate.
Answer: Meera violates Standard II(B). Cornering the deliverable supply to exploit and distort a related derivative is transaction-based manipulation.
The deciding factor in II(B) is intent. The Standard is not meant to catch legitimate strategies that exploit genuine market inefficiencies, even when they look aggressive, and legitimate activity can appear unusual in a thin or volatile market without being manipulation. What separates a violation from hard-nosed trading is the purpose of deceiving other participants about price or activity. A trade placed to profit from a real mispricing is fine; a trade placed to create a false impression is not.
Because intent is hard to see directly, regulators and firms watch for patterns that often accompany manipulation: orders entered for unusually short periods, orders that would not change beneficial ownership, orders placed only to move the quoted price and then cancelled, activity split across platforms to disguise it, or coordinated trading among a few participants in a small market. None of these is proof by itself, but together they are the signatures compliance systems are built to flag.
| Pattern | Why it is suspicious |
|---|---|
| Orders live for an unusually short time | Suggests an aim to move a quote rather than to trade |
| Orders that do not change beneficial ownership | Points to wash trading that fakes activity |
| Orders cancelled just before execution | Suggests an attempt to shift the bid or offer, not to deal |
| Activity split across venues | Can be an effort to disguise coordinated manipulation |
| Coordinated trading in a thin market | A few participants can distort a market with little liquidity |
Read the warning signs as prompts for a question, not as verdicts. Each can appear in perfectly legitimate trading, a large order worked carefully, a cancelled order that simply reflected a change of mind, so the presence of a pattern invites scrutiny of intent rather than an automatic conclusion. That is why surveillance flags conduct for review rather than punishing it outright, and why, in the end, the professional standard rests on your own honesty about why you are placing an order and what impression you intend it to create.
The recommended compliance practices follow from this. Firms should have procedures to prevent placing and cancelling orders intended to deceive, run real-time or systematic surveillance across platforms to catch suspicious order entries, wash trading, and cross-product manipulation, and use automated order-management controls to screen for manipulative orders before they reach the market. The professional’s own duty is simpler: never trade with the intent to mislead, and never lend a hand to anyone who does.
One more distinction saves candidates on the exam: the difference between manipulation and mere disclosure of a genuine position. Announcing that you have taken a large stake in a company, or publishing honest analysis that happens to move a price, is not manipulation, because there is no intent to deceive and the information is true. Manipulation requires that the price or volume signal be made false on purpose. So a manager who truthfully explains a bullish thesis and discloses their holding is fine, while a manager who invents a rosy story to lure buyers, or trades to fake activity, is not. Truth and intent, not the size of the market impact or how dramatic the price move happens to be, are what the Standard weighs.
Setup. Two traders at the fictional Tungabhadra Partners repeatedly trade the same illiquid instrument back and forth between accounts they both control, creating the appearance of heavy demand, to draw in outside buyers before selling out.
Answer: the traders violate Standard II(B). Fabricating the appearance of activity through wash trades to lure in buyers is transaction-based manipulation.
For II(B), always locate the intent to deceive. The same aggressive-looking trade can be legitimate (exploiting a real inefficiency) or manipulative (manufacturing a false price or volume) depending on purpose. When a scenario stresses that a trader “knew or should have known” the action would distort the market, or that trades changed no real ownership, you are looking at manipulation.
An analyst assembles a material conclusion from public data and several non-material comments from suppliers, then trades on it. Compliant or a violation?
Compliant, under the mosaic theory. The conclusion is the product of analysis of public and non-material nonpublic information, not a material secret handed to the analyst. Documenting the sources is the recommended safeguard.
When does information stop being “nonpublic”?
When it has been disseminated to the marketplace in general, so that investors at large have access to it. Information known only to a few analysts, or selectively disclosed, remains nonpublic until it is broadly released.
What is the main recommended procedure for preventing misuse of material nonpublic information within a firm?
An information barrier, or firewall, that stops such information from crossing between conflicted parts of the firm. It is supported by restricting proprietary trading in affected securities, reviewing personal trading, and maintaining watch and restricted lists.
What single factor decides whether aggressive trading is market manipulation?
Intent. Standard II(B) targets trading meant to deceive others by distorting price or volume. Legitimate strategies that exploit real inefficiencies are not violations, even if they appear unusual in a thin or volatile market.
A company posts material results to a widely followed exchange feed at exactly 10:00. May you trade the security at 10:00 and one second, immediately after the release?
Not necessarily. Information is public only once it has been disseminated to the market at large and the market has had a chance to receive and absorb it. Trading in the instant after a release, before the market can actually react, can still be trading ahead of the public.
An analyst reaches a bullish view partly by combining public filings with one material figure that a company officer disclosed to her privately before any announcement. Is this the mosaic theory or a violation?
A violation. The mosaic theory covers conclusions built only from public and non-material nonpublic pieces. Once a material nonpublic fact is part of the mix, possession of that fact bars trading, and the surrounding analysis does not cure it.
A fund manager truthfully announces that the fund has taken a large stake in a company and honestly explains the bullish thesis, and the price rises. Is that market manipulation?
No. There is no intent to deceive and the information is true. Standard II(B) requires that the price or volume signal be made false on purpose; honest disclosure of a genuine position and honest analysis are legitimate even when they move the price.
II(A) Material Nonpublic Information and II(B) Market Manipulation. Together they protect the integrity of capital markets: II(A) by barring trading on price-moving information the market does not yet have, and II(B) by prohibiting the distortion of prices or volume to deceive other participants.
Information is material if it would likely affect a security’s price or a reasonable investor would want it before deciding; materiality depends on the reliability of the source, the clarity of the price effect, and timing. It is nonpublic until it has been disseminated to the marketplace in general, so information known to only a few remains nonpublic.
The principle that an analyst may combine public information with non-material nonpublic information to reach a conclusion that is itself material, and may act on that conclusion. The conclusion is the product of analysis, not a leaked secret, so it does not violate Standard II(A). Analysts should document their sources to show the conclusion was built this way.
No. Standard II(A) applies however you obtained the information, including by accident or through selective disclosure. Possessing material nonpublic information bars you from acting on it or causing others to act, regardless of whether you sought it out.
A firewall, or information barrier, is a set of controls that prevents material nonpublic information from moving between parts of a firm that should not share it, such as investment banking and research or brokerage. It is the main recommended procedure under Standard II(A), supported by restricting proprietary trading, reviewing personal trading, and keeping watch and restricted lists.
Information-based manipulation uses false or misleading information to move a price, such as a pump and dump or spreading false rumours. Transaction-based manipulation uses the trades themselves to distort price or volume, such as wash trades, fictitious activity, or cornering a position to exploit a related derivative.
By intent. Standard II(B) targets trading meant to deceive others about price or activity. Strategies that exploit genuine market inefficiencies are legitimate, even if they look aggressive or unusual in a thin market. Warning signs of manipulation include orders that change no beneficial ownership, orders placed only to move a quote and then cancelled, and coordinated trading in a small market.
Through scenarios asking whether conduct complies or violates and which sub-section applies. Mosaic-theory questions are especially common: watch for whether a material fact was handed over (a violation to trade on) or a material conclusion was built from public and non-material pieces (legitimate). For II(B), look for intent to deceive and for ownership-neutral or price-moving orders.
