Key Regulatory Red Flags for Investors
- Unauthorized Trading: Making trades without a client’s prior written consent and without firm approval, a violation of FINRA Rule 3260. This was at the heart of recent regulatory findings against Lannister.
- Churning/Excessive Trading: Engaging in excessive transactions to generate commissions, potentially regardless of your investment objectives or risk profile.
- Misrepresentation: Providing inaccurate or incomplete information about investments, costs, or risks—such as failing to adequately explain annuity riders or misrepresenting compensation.
- Compliance Questionnaire Irregularities: Inaccurate or misleading answers on firm compliance checks further erode trust and can mask ongoing issues.
How These Issues Can Affect Your Investment Accounts
Excessive trading, unauthorized discretion, and misrepresentation can erode account value, increase risks, and result in substantial financial losses.
