Best Execution
Best Execution
The duty to seek the most favorable terms reasonably available when executing client transactions, considering all qualitative and quantitative factors beyond just price. Factors include speed of execution, certainty of settlement, commission costs, and market impact. Broker-dealers have explicit best execution obligations under FINRA rules. Investment advisers, while not subject to specific best execution rules, must seek favorable execution terms as part of their broader fiduciary duty to act in clients' best interests.
An adviser executing a large block trade evaluates three broker-dealers: Broker A offers $0.01/share commission but 2-minute execution delay, Broker B offers $0.02/share with instant execution and price improvement, and Broker C offers $0.015/share with 30-second delay. The adviser chooses Broker B because the faster execution and price improvement provide better overall value despite slightly higher commissions, demonstrating best execution by considering multiple factors beyond just the lowest commission rate.
Best execution does NOT mean lowest price or lowest commission. It requires evaluating multiple factors (price, speed, certainty, market impact) to achieve the most favorable overall terms. Many students incorrectly assume best execution means always choosing the cheapest commission, but regulators expect a qualitative analysis of what combination of factors serves the client best.
How This Is Tested
- Evaluating which broker provides best execution across multiple factors (price, speed, certainty, commission)
- Distinguishing best execution (overall favorable terms) from lowest price or lowest commission
- Understanding documentation requirements for demonstrating best execution compliance
- Recognizing best execution obligations in discretionary vs. non-discretionary accounts
- Identifying best execution violations when advisers prioritize their own interests (directed brokerage, soft dollars)
Regulatory Limits

Example Exam Questions
Test your understanding with these practice questions. Select an answer to see the explanation.
Thomas, an investment adviser, needs to execute a 50,000 share order of a thinly traded stock for a client. He evaluates three broker-dealers: Broker X charges $0.02/share commission with guaranteed execution within 1 hour but may cause market impact due to their aggressive trading style. Broker Y charges $0.03/share with a 3-hour execution window but uses algorithms to minimize market impact. Broker Z charges $0.015/share but cannot guarantee execution timeframe or price. The client needs the position established by market close for tax purposes. Which broker best demonstrates best execution for this scenario?
B is correct. Best execution requires considering all relevant factors in the specific context. Here, the client's need to establish the position by market close for tax purposes makes certainty and speed of execution paramount. Broker X's guaranteed 1-hour execution meets this critical timing requirement, making it the best choice despite slightly higher costs and potential market impact. The risk of failing to execute (Broker Z) or missing the deadline (Broker Y's 3-hour window) would be worse than the additional costs.
A incorrectly prioritizes lowest commission over certainty of execution. Best execution is NOT synonymous with lowest cost; Broker Z cannot guarantee execution, creating unacceptable risk given the client's tax deadline. C overemphasizes market impact at the expense of certainty. While minimizing market impact matters, it is not always the primary consideration when execution certainty is critical. D is incorrect because splitting the order does not address the fundamental issue that only Broker X can guarantee timely execution, and unnecessarily complicating the execution could increase overall costs and risks.
The Series 65 exam tests your understanding that best execution is context-dependent and requires weighing multiple factors based on the specific circumstances. No single factor (price, speed, commission) is determinative. advisers must evaluate what combination of factors provides the most favorable overall terms for the particular transaction and client needs.
Which of the following BEST describes the best execution obligation for investment advisers?
C is correct. Best execution is defined as the duty to seek the most favorable terms reasonably available when executing client transactions. This requires considering multiple qualitative and quantitative factors including price, speed, likelihood of execution and settlement, commission costs, and market impact. No single factor is determinative; advisers must evaluate the totality of circumstances.
A is incorrect because best execution does NOT mean lowest commission. An adviser might reasonably pay higher commissions if other factors (speed, certainty, reduced market impact, better price improvement) provide superior overall value. B is incorrect because best execution relates to the quality of execution terms, not the speed of order placement. There is no 24-hour requirement. D is incorrect and potentially describes a soft dollar arrangement. Best execution requires evaluating execution quality, not selecting brokers based on research they provide to the adviser (which could be a conflict of interest).
The Series 65 exam frequently tests whether candidates understand that best execution is NOT synonymous with lowest price or fastest execution. It requires a holistic evaluation of multiple factors to achieve the most favorable overall terms. This multi-factor analysis is central to demonstrating fiduciary duty in transaction execution.

Access Free BetaAn investment adviser has been routing all client equity trades to a single broker-dealer that charges commissions 15% higher than the industry average. The adviser maintains detailed quarterly reports showing that this broker consistently achieves price improvement averaging $0.03 per share better than the national best bid/offer (NBBO), resulting in net savings for clients despite higher commissions. The adviser reviews execution quality quarterly and documents the analysis. Has the adviser satisfied their best execution obligation?
C is correct. The adviser has satisfied best execution obligations by demonstrating that despite higher commissions (15% above average), the broker achieves superior price improvement (averaging $0.03 per share better than NBBO), resulting in net benefits to clients. The adviser also maintains documentation and conducts regular quarterly reviews, which demonstrates the required "regular and rigorous" evaluation of execution quality. Best execution focuses on overall favorable terms, not individual components.
A is incorrect because best execution does NOT require using the lowest commission rates. The total value proposition (price improvement, execution quality, certainty) matters more than any single factor. Here, the consistent price improvement more than offsets the 15% commission premium. B is incorrect because there is no regulatory requirement to diversify execution among multiple broker-dealers. Advisers may use a single broker if that broker consistently provides best execution and the adviser regularly evaluates this through documented reviews. D is incorrect because best execution does not require trade-by-trade disclosure. The higher commissions should be disclosed in Form ADV Part 2A as part of the adviser's general brokerage practices, but pre-trade disclosure is not required if the adviser can demonstrate overall best execution.
The Series 65 exam tests your understanding that best execution is evaluated holistically and requires documentation. Advisers can justify higher commissions if other factors (price improvement, execution quality) provide net benefits to clients. Regular reviews and documentation of the decision-making process are critical to demonstrating compliance with best execution obligations.
When evaluating best execution for a client transaction, an investment adviser should consider all of the following factors EXCEPT
C is correct (the EXCEPT answer). The broker-dealer's willingness to provide free research to the adviser is NOT a legitimate best execution factor. This describes a soft dollar arrangement where the adviser might be tempted to use a broker based on services provided to the adviser rather than execution quality for the client. Selecting brokers based on benefits to the adviser (rather than client execution quality) violates fiduciary duty and best execution obligations.
A is a valid factor: Speed and likelihood of execution and settlement are core best execution considerations, especially for time-sensitive trades or illiquid securities. B is a valid factor: Total commission and transaction costs are quantitative factors that must be evaluated as part of overall execution quality. D is a valid factor: Market impact (how the trade itself might move the security's price) is particularly important for large orders or thinly traded securities and is a legitimate best execution consideration.
The Series 65 exam tests your ability to distinguish legitimate best execution factors (that benefit clients) from adviser-focused considerations (that benefit the adviser). Using a broker because they provide research to the adviser is a conflict of interest and potential soft dollar issue, not a best execution consideration. Advisers must focus solely on factors that contribute to favorable execution terms for clients.
An investment adviser uses multiple broker-dealers to execute client trades and maintains a best execution committee that meets quarterly to review execution quality. The committee analyzes execution data and considers whether to add or remove broker-dealers from the approved list. Which of the following statements about this arrangement are accurate?
1. The adviser must use the broker with the lowest commission on every trade to satisfy best execution
2. Quarterly reviews are sufficient to demonstrate regular and rigorous evaluation of execution quality
3. The adviser must maintain documentation of the committee's analysis and decisions
4. Best execution requires the adviser to guarantee that every trade receives the best possible price
A is correct. Only statements 2 and 3 are accurate.
Statement 1 is FALSE: Best execution does NOT require using the broker with the lowest commission on every trade. Advisers must consider multiple factors (speed, certainty, price improvement, market impact) and may reasonably pay higher commissions if other factors provide superior overall value. Best execution is about the most favorable overall terms, not individual components.
Statement 2 is TRUE: Quarterly reviews are generally considered sufficient to satisfy the "regular and rigorous" review requirement for best execution. While no specific frequency is mandated by regulation, quarterly reviews are an industry best practice and demonstrate ongoing diligence in evaluating execution quality.
Statement 3 is TRUE: The adviser must maintain documentation of best execution reviews, including the committee's analysis, factors considered, data evaluated, and decisions made. This documentation demonstrates compliance with best execution obligations and provides evidence of reasonable diligence in seeking favorable execution terms.
Statement 4 is FALSE: Best execution requires seeking the most favorable terms "reasonably available," not guaranteeing the best possible price on every trade. Markets are dynamic and prices fluctuate. The standard is reasonable diligence and process, not perfect outcomes. Advisers cannot guarantee execution results but must demonstrate a reasonable process for seeking best execution.
The Series 65 exam tests your understanding of best execution as a process-based obligation requiring regular review and documentation, not a guarantee of perfect outcomes. Advisers must establish reasonable procedures (like quarterly committee reviews), document their analysis, and demonstrate they considered appropriate factors. The focus is on the quality of the process and diligence, not on guaranteeing the best possible result for every individual trade.
💡 Memory Aid
BEST = Beyond price. Best execution is NOT cheapest execution. Think of buying a flight: Best overall value considers price, Execution time (flight duration), Security of arrival (certainty), and Total costs (baggage fees). The cheapest ticket with 3 layovers is NOT always "best execution" for your trip.
