Insider Trading

Standard II(A) turns on two independent conditions, and information must satisfy both before a prohibition attaches. Information is material if a reasonable investor would want it before deciding to trade, or if its release would likely move the security's price. Earnings that will miss guidance, an unannounced merger, the loss of a dominant customer, a regulatory rejection, or the death of a key executive are typically material. Ambiguous, speculative or unverified items are usually not, and the more uncertain the source and the less specific the content, the weaker the materiality claim.

Information is nonpublic until it has been broadly disseminated to the marketplace or the market has had a reasonable opportunity to react to it. Disclosure to a select group of analysts, a private call with a portfolio manager, or a draft press release does not make information public. Conversely, information that is material but genuinely public, such as a filed disclosure that the market has not yet digested, may be traded on freely; diligence in reading what others ignore is legitimate advantage.

The standard prohibits three distinct acts. First, trading or causing others to trade in a security whose value would likely be affected by the information. Second, communicating the information to anyone outside the relationship that gave rise to it, including colleagues, clients, family or the press, whether or not the recipient trades and whether or not the tipper profits. Third, using the information to alter recommendations, model portfolios or client advice, since indirect action carries the same consequence as a direct trade.

How the information arrived is irrelevant. A member who receives material nonpublic information by accident, from a talkative issuer, from a supply-chain contact or through a misdirected message is bound the moment it is recognized as material and nonpublic. The correct response is to make reasonable efforts to have the issuer disclose it publicly, notify compliance or supervisory personnel, and refrain from trading or recommending the security in the meantime. Selective disclosure by an issuer excuses nothing; the burden shifts to the recipient.

In practice the risk concentrates in firms that combine investment banking, research, sales and asset management. The recommended control is an information barrier that physically and procedurally separates departments holding deal information from those trading or publishing on the same names, supported by review of interdepartmental communication, documented approval for any wall-crossing, and monitoring of proprietary and personal trading.

Firms typically maintain a watch list, known to very few and used to surveil activity in sensitive names, and a restricted list that is distributed more widely and blocks trading and recommendation in those securities. Removing a name from research coverage abruptly can itself signal information, so continuing to publish only what is consistent with prior coverage is preferred. Where proprietary trading must continue, some firms act as passive market makers or execute only unsolicited client orders, and they document the rationale.

Candidates should be able to take a fact pattern and classify each item of information along both axes: material or not, public or not. Only the intersection triggers the prohibition. Mosaic construction, in which an analyst combines public filings, industry data, site visits and nonmaterial nonpublic details into a differentiated conclusion, is permitted and is a legitimate source of alpha; the recommended safeguard is to keep records of the sources and reasoning that support the conclusion.

Expect scenarios involving overheard conversations, expert-network consultants, issuers that leak selectively, and analysts pressured by portfolio managers to act on a tip. The defensible answer almost always combines three elements: do not trade or recommend, do not pass the information along, and escalate to compliance while urging public disclosure. Note also that Standard II(A) applies even where local securities law is silent or more permissive, because members must follow the stricter of law and the Code and Standards.
