Explanation

Mike Leung has violated Standard V(B) - Communication with Clients and Prospective Clients. According to this standard, members must:

1. Disclose the basic format and general principles of the investment processes used to analyze investments
2. Disclose significant limitations and risks associated with the investment process
3. Distinguish between fact and opinion in the presentation of investment analysis
4. Disclose the general principles of the formats used to select investments and construct portfolios

Why posting only a recommended stock list violates the standard:

• Simply posting a list of recommended stocks without providing the supporting analysis, methodology, or limitations is insufficient
• The statement "additional information will be available upon request" does not fulfill the requirement for adequate communication
• Clients need to understand the basis for recommendations to make informed decisions

Why using social media is NOT the violation (Option C is incorrect):

• There is no prohibition against using social media to communicate with clients
• The medium of communication is not the issue; the content and completeness of the communication is what matters
• As long as appropriate disclosures are made, social media can be a valid communication channel

Correct answer: B - Leung violated the Standards by posting only a recommended stock list without providing the necessary supporting analysis and disclosures that would allow clients to understand the basis for the recommendations.
