Ameriprise Financial Advisor Larry David Nelson Subject of Pending Customer Dispute Seeking Over $1.88 Million, Alleging Reg BI Violations and Unauthorized Trading

• September 21, 2026
• Ameriprise Financial Services

Larry David Nelson (CRD# 2275834) is a financial advisor with Ameriprise Financial Services, LLC in Salinas, California. According to his FINRA BrokerCheck report, Nelson is registered as both a broker and an investment adviser, and his SEC IAPD report lists him as an investment adviser.

Broker’s History

BrokerCheck shows Nelson has been in the securities industry for 33 years and has been registered with two firms:

• IDS Life Insurance Company, November 1992 to July 2006 (broker)
• Ameriprise Financial Services, LLC, 1992 to present (broker) and December 1997 to present (investment adviser)

Customer Disputes

BrokerCheck reports two customer disputes.

Pending (8/6/2026). Customers allege that Nelson violated Regulation Best Interest, breached his fiduciary duties, engaged in unauthorized trading, and used predatory sales practices in managing their portfolio from 2015 through 2026. They seek $1,881,039.19 in damages. The matter is pending, and the allegations have not been proven.

Denied (4/22/2003). Customers alleged that Nelson mismanaged their investments and that they suffered losses as a result. They requested $72,489, and the claim was denied. Nelson’s BrokerCheck comment states that the customers described themselves as moderate-to-aggressive investors, that the investments were suitable, and that the customers had ample opportunity to make changes.

The Legal Standards

The rules below explain what brokers and advisers owe their customers. They are not findings about Nelson.

Suitability (FINRA Rule 2111). From 2012 until June 30, 2020, FINRA Rule 2111 required a broker to have a reasonable basis to believe that a recommended transaction or investment strategy was suitable for the customer. The broker had to make that judgment based on reasonable diligence into the customer’s investment profile, including age, other investments, financial situation and needs, tax status, objectives, experience, time horizon, liquidity needs, and risk tolerance. The rule has three components:

• Reasonable-basis suitability: the broker understands the risks and rewards of the product and reasonably believes it is suitable for at least some investors.
• Customer-specific suitability: the recommendation fits the particular customer’s profile.
• Quantitative suitability: a series of recommended transactions, even if suitable individually, is not excessive when taken together. Turnover rate, cost-to-equity ratio, and in-and-out trading can support a finding of excessive activity.

The rule covers recommendations to hold a security, and a broker cannot disclaim suitability obligations. A customer’s stated risk tolerance is only one factor in the analysis. It does not replace it.

Unauthorized trading (FINRA Rules 3260 and 2010). FINRA Rule 3260(b) prohibits a registered representative from exercising discretion in a customer’s account unless the customer has given prior written authorization to a stated individual and the firm has accepted the account in writing. The only built-in exception is narrow. Under Rule 3260(d)(1), a broker may use time-and-price discretion only on an order the customer has already given for a definite amount of a specified security, and that authority ends at the close of the business day unless the customer signs and dates a written extension. A broker who chooses the security, the quantity, or the timing of a trade without the customer’s approval is exercising discretion. FINRA generally treats a rule violation as also inconsistent with Rule 2010, which requires high standards of commercial honor and just and equitable principles of trade.

Two related points matter to investors:

• Suitability is not a defense. A trade can be unauthorized even if the investment would have been suitable. The two claims are independent and are often pleaded together.
• Firms have supervisory duties. Rule 3260(c) requires the firm to approve each discretionary order promptly in writing and to review discretionary accounts at frequent intervals. Rule 3260(a) separately bars transactions in discretionary accounts that are excessive in size or frequency. Where a firm failed to detect unauthorized activity, investors may have a failure-to-supervise claim against it.

Best interest and fiduciary duty. Since June 30, 2020, Regulation Best Interest has governed a broker’s recommendations to retail customers, and Rule 2111 no longer applies to those recommendations. Reg BI’s Care Obligation requires reasonable diligence, care, and skill to:

• understand the risks, rewards, and costs of a recommendation;
• have a reasonable basis to believe it is in the best interest of the particular customer, without placing the broker’s interest ahead of the customer’s; and
• have a reasonable basis to believe that a series of recommended transactions is not excessive.

Advice given in an advisory capacity is governed instead by the adviser’s fiduciary duty under the Advisers Act. The SEC has stated that this duty includes a duty of care (advice in the client’s best interest, based on the client’s objectives, with monitoring over the course of the relationship) and a duty of loyalty (Release IA-5248). For a dually registered professional, which standard applies can depend on the type of account and the capacity in which the advice was given.

Recovering Losses

The SEC has said that Reg BI does not create a new private right of action. In FINRA arbitration, however, investors routinely plead violations of FINRA rules and Reg BI as evidence of the standard of care underlying claims for negligence, breach of fiduciary duty, breach of contract, and violations of state securities laws. Timing also matters. Under FINRA Rule 12206, a claim is not eligible for FINRA arbitration once six years have elapsed from the occurrence or event giving rise to it. That is an eligibility rule and not a statute of limitations, and the panel decides when the period began. Investors who suspect unauthorized trading, an unsuitable strategy, or a breach of fiduciary duty should review their account records and consult counsel promptly. Please note that a customer dispute reflects allegations only, and a pending matter has not been adjudicated.
