| The situation | The comfortable (wrong) reading | The disciplined call |
|---|---|---|
| You disclosed a commission conflict in the fine print, then still steered the client into the higher-paying near-identical fund | Disclosure was made, so the duty is discharged | Disclosure does not transfer the duty back to the client; acting on the disclosed conflict is still a breach |
| A market-moving note goes to premium clients at 9:00 and standard clients at 11:00 on the same research | Premium clients paid more, so the head start is just the product | Staggering the same price-sensitive research lets one group trade ahead of another -- a structured front-run, not a service tier |
| A friend, not employed by the company, repeats a CFO's not-yet-announced earnings miss to you and you sell | You are an outsider with no job at the company, so you are free to act on it | A tippee inherits the duty: material, nonpublic, passed through a breached confidence -- illegal regardless of your title, and selling counts the same as buying |
| You out-research the market using only public filings and lawful expert calls and gain a real edge | Any pre-earnings edge must be insider trading | This is the lawful mosaic theory -- the edge is legitimate because no decisive piece is material, nonpublic, and improperly sourced |
When a case feels ambiguous, run the one test the whole path reduces to: would this choice survive being explained, in plain words, to the client whose interest you owe? 'I disclosed it in the fine print and then did it anyway,' 'I let the higher-paying clients trade ahead of you on the same note,' and 'I traded on a tip I knew came from inside' all fail that test instantly. The rule you are looking for is usually the one the comfortable answer is trying not to apply.
Ethics is judgment under ambiguity, and the comfortable answer is usually the one avoiding the rule. Three reflexes carry you through almost every hard case: disclosure is a floor and never permission; fairness is about sequence and access, so trading ahead of what someone is entitled to is front-running even when the view is right; and an edge is lawful or not by its source alone -- the public, non-confidential mosaic is the system working, one breached secret is the system cheated. This is the trust layer the entire rest of your analysis -- valuation, accounting, every signal you will learn here -- quietly stands on: skill the market can rely on only because it was come by honestly.
Sit with the ideas.
An analyst builds a strong 'Buy' thesis purely from public 10-K filings, lawfully purchased satellite images of store parking lots, and interviews with industry consultants who share no confidential client data -- then buys before earnings. A colleague says: 'You clearly have an edge before the print -- that's basically insider trading.' Who is right?
