Unauthorized trading remains one of the most common complaints filed with FINRA. It occurs when a broker buys or sells securities without obtaining the customer’s prior approval. The practice often generates excessive commissions while exposing investors to unsuitable risk. Regulators have sanctioned dozens of firms and individual brokers for this violation in recent years.
What happened
FINRA Rule 3260 governs discretionary accounts. A broker must obtain written authorization from the customer and written acceptance from the firm before exercising discretion. Despite these clear requirements, some brokers bypass the paperwork and trade freely in customer accounts.
The consequences can be severe. Investors may find positions they never requested. They may face unexpected margin calls. Capital gains taxes can accrue on trades executed for the broker’s benefit, not the customer’s.
Key facts
| Regulatory Rule | Requirement | Penalty |
|---|---|---|
| FINRA Rule 3260 | Written authorization + firm acceptance | Fine, suspension, or bar |
| FINRA Rule 2111 | Suitability obligation | Restitution to investors |
| SEC Rule 15b10-3 | Record-keeping for discretionary trades | Civil monetary penalties |
Between 2019 and 2024, FINRA reported an average of 120 unauthorized trading cases annually. Restitution ordered in these cases totaled more than $42 million. The median individual award to harmed investors approached $78,000.
Investor impact
Unauthorized trading harms investors in three ways. First, commissions erode principal. Second, unsuitable positions expose accounts to volatility the investor never agreed to accept. Third, tax consequences from rapid turnover reduce after-tax returns.
Senior investors are disproportionately affected. A 2023 FINRA study found that investors over age 65 filed 34 percent of all unauthorized trading complaints, despite representing a smaller share of brokerage accounts overall.
Red flags investors should watch
| Warning Sign | What It Means |
|---|---|
| Trades appear you did not approve | Possible unauthorized discretion |
| High turnover in a conservative account | Potential churning or unauthorized activity |
| Margin debt you did not request | Broker may have overreached authority |
| Statements show unfamiliar positions | Immediate review is warranted |
Investors should review monthly statements promptly. Any trade not personally authorized should be questioned immediately. Delays can complicate recovery.
Regulatory precedent and market-wide impact
FINRA has signaled stricter enforcement on discretionary account violations. A 2024 regulatory notice reminded firms that written authorization must precede any discretionary trade, not merely accompany it. Firms failing to supervise discretionary accounts have faced combined fines exceeding $12 million in the past three years.
The market-wide effect is increased compliance costs passed to investors through higher fees. Some smaller broker-dealers have exited discretionary account services entirely, reducing options for investors who legitimately prefer delegated management.
What investors can do now
Document every unauthorized trade. Gather monthly statements, trade confirmations, and any correspondence with the broker. File a complaint with FINRA’s Office of Dispute Resolution. Consider arbitration to recover losses and commissions.
Investors may also file a complaint directly with the brokerage firm’s compliance department. Firms are required to investigate and respond under FINRA regulations.
