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?

  1. AStandard II(B), Market Manipulation, by disseminating false information to distort the security's price
  2. BStandard III(B), Fair Dealing, because she did not treat all clients equally when covering the position
  3. CStandard V(A), Diligence and Reasonable Basis, because her investment thesis lacked adequate research support
  4. DNo violation occurred because the post was made anonymously and cannot be traced to her employer
Show answer & 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.
