Terms in This Cluster (6)

Breakpoint

high

The investment threshold at which mutual fund sales charges (loads) decrease, encouraging larger investments through volume discounts. Breakpoints typically occur at specific dollar amounts ($25K, $50K, $100K, $250K, etc.). Brokers must disclose available breakpoints and inform clients of rights of accumulation and letters of intent. Selling shares just below a breakpoint to avoid the reduced load (and earn higher commission) is a prohibited practice called a "breakpoint sale."

Example: A fund charges 5.75% on investments under $50K, 4.50% for $50K-$99K, and 3.75% for $100K+. An invest...

Churning

high

Excessive trading in a client's account to generate commissions without regard to the client's investment objectives. Requires three elements: control over the account, excessive trading activity, and intent to generate commissions. A prohibited practice that violates fiduciary duty and suitability standards.

Example: An adviser with discretionary authority buys and sells the same securities multiple times per month ...

Front-Running

high

The prohibited practice of trading in a security ahead of a client's order to profit from the anticipated price movement caused by the client's trade. Constitutes a severe breach of fiduciary duty and misuse of material non-public information. Violates both state and federal securities laws.

Example: An investment adviser receives a $5 million buy order for ABC stock from a pension fund client. Befo...

Insider Trading

high

Trading securities based on material, non-public information (MNPI). Both elements must be present: information must be material (would affect investment decisions) AND non-public (not available to the general investing public). Violations result in civil penalties (up to 3x profits), disgorgement of profits, and imprisonment up to 20 years.

Example: A corporate CFO learning of an upcoming merger and buying stock before the public announcement const...

Material Misrepresentation

high

A false or misleading statement or omission of fact that a reasonable investor would consider important in making an investment decision. Prohibited under Investment Advisers Act Section 206, materiality is judged by whether the misrepresentation would likely influence a reasonable investor's decision. Both affirmative false statements and material omissions violate anti-fraud provisions.

Example: An adviser tells a client that a mutual fund "has never had a down year" when the fund actually lost...

Quantitative Suitability

high

The third prong of FINRA Rule 2111 suitability obligations, requiring the broker-dealer to have a reasonable basis to believe that a series of recommended transactions is not excessive in light of the customer's investment profile. Addresses churning and over-trading concerns by evaluating the frequency and volume of transactions collectively, even when each individual trade may be suitable.

Example: A broker recommends five different suitable equity trades to a conservative retiree over two weeks, ...
