An analyst at a hedge fund holds a large short position in a small-cap company. Using an anonymous social media account, she posts a message claiming the company is under active SEC investigation for accounting fraud, a claim she knows to be false. The stock price drops sharply, and she covers her short position at a profit before the rumor is debunked. Which Standard has the analyst most likely violated?
- AStandard II(B), Market Manipulation, by disseminating false information to distort the security's price
- BStandard III(B), Fair Dealing, because she did not treat all clients equally when covering the position
- CStandard V(A), Diligence and Reasonable Basis, because her investment thesis lacked adequate research support
- DNo violation occurred because the post was made anonymously and cannot be traced to her employer
Show answer & explanationAnswer & explanation
Correct answer: A. Standard II(B), Market Manipulation, by disseminating false information to distort the security's price
Standard II(B) prohibits both transaction-based and information-based manipulation; spreading false or misleading information to artificially affect a security's price for personal gain is a classic example of information-based manipulation. Anonymity does not excuse the conduct—the Code applies to the individual's actions regardless of attribution, and personal accounts are not covered here.
Why the other options are wrong
- B. Fair dealing concerns client treatment, not spreading false market information.
- C. Diligence concerns the basis for investment recommendations, not the deliberate spreading of false rumors.
- D. Anonymity does not eliminate the ethical violation; the Code applies to conduct, not just attributable statements.
Information-Based Manipulation (II(B))
Spreading false or misleading information, or information known to be false, with the intent to mislead market participants and distort security prices for personal gain.
- II(B) covers both transaction-based (e.g., wash trades) and information-based manipulation
- Intent to distort price or mislead is the key element
- Applies regardless of anonymity or medium used
Memory trick: Lies that move the price are manipulation in disguise.
