Explanation

Julia Stevens has violated the Standard relating to loyalty, specifically by failing to inform her firm's compliance department about her colleague's activity.

Key Standards Analysis:

• Standard IV(A): Loyalty to Employer requires members to act for the benefit of their employer and not deprive the employer of the advantage of their skills and abilities
• Standard I(A): Knowledge of the Law requires members to understand and comply with applicable laws, rules, and regulations

Application to the Scenario:

Violation - Colleague's Trading Activity:

• Stevens observed her colleague engaging in potential market manipulation (exploiting price differences across exchanges)
• This activity could constitute illegal trading practices
• Despite the firm having no specific employee trading policy, Stevens had a duty to report potentially illegal activities to her compliance department
• Failure to report this activity violates her duty of loyalty to her employer

No Violation - Brokerage Fees:

• Stevens correctly refused to pay unjustifiably high brokerage fees
• Standard III(A): Loyalty, Prudence, and Care requires members to act for the benefit of clients
• Paying excessive fees without sufficient client benefit would violate her duty to clients
• Her refusal to comply with this improper request was appropriate

Conclusion:

Stevens violated her duty of loyalty by failing to report her colleague's potentially illegal trading activity, which could expose the firm to regulatory and reputational risk.
