SEC Exam Priorities: Algorithmic Trading Platforms

📅 Updated Dec 2025 ⏱ 22 min read 🔍 SEC Examinations

2025 OCIE Exam Priorities Overview

The SEC's Division of Examinations (formerly OCIE - Office of Compliance Inspections and Examinations) publishes annual examination priorities that signal where regulatory scrutiny will be most intense. For algorithmic trading platforms, investment advisers using automated systems, and quantitative trading firms, understanding these priorities is essential for examination readiness.

In 2025, the SEC has made clear that algorithmic trading, AI-driven investment tools, and automated portfolio management systems are top-tier examination priorities. This isn't a passing interest - the SEC has dedicated specialized teams to understanding and examining these technologies.

Why Algorithmic Trading Is a Priority

The SEC's focus on algorithmic trading stems from three core concerns: (1) the potential for systemic risk from automated systems, (2) the difficulty of traditional compliance oversight on "black box" algorithms, and (3) investor protection concerns when advice comes from machines rather than humans. These concerns mean heightened scrutiny and more detailed document requests.

Key 2025 Focus Areas for Algo Platforms

Algorithm Governance

  • Development and testing protocols
  • Change management procedures
  • Model validation practices
  • Risk limit monitoring
  • Kill switch and error handling

AI/ML Disclosures

  • Marketing accuracy vs. reality
  • Form ADV completeness
  • Model assumptions disclosure
  • Performance attribution clarity
  • Limitations and risks explained

Fiduciary Compliance

  • Suitability of algo recommendations
  • Conflicts embedded in models
  • Best execution for auto trades
  • Client interest vs. firm revenue
  • Ongoing monitoring adequacy

Algorithmic Trading Focus Areas

Based on the 2025 exam priorities, recent risk alerts, and enforcement actions, the SEC will concentrate on these specific areas when examining algorithmic trading platforms.

1. Algorithm Design and Development

Examiners want to understand how my algorithms were designed, who designed them, and what objectives they're optimized to achieve.

Focus AreaWhat Examiners Look ForCommon Issues
Design Documentation Written specifications, logic diagrams, decision trees Verbal agreements with no documentation
Optimization Target What the algorithm is designed to maximize or minimize Optimizing for firm revenue not client returns
Training Data Data sets used to train ML models, time periods covered Survivorship bias, regime dependency
Development Team Qualifications of developers, oversight structure Developers with no investment expertise
Version Control Change tracking, rollback capability, audit trails No record of algorithm changes over time

2. Model Risk Management

The SEC expects firms to have robust model risk management frameworks that identify, measure, and mitigate risks inherent in algorithmic systems.

OCC SR 11-7 as Guidance

While the OCC's SR 11-7 "Supervisory Guidance on Model Risk Management" applies to banks, the SEC has referenced similar principles for investment advisers. The framework - validation, ongoing monitoring, and governance - provides a useful template for algorithmic trading compliance.

3. Pre-Trade Risk Controls

Automated trading systems must have controls that prevent erroneous or unauthorized trades before they execute.

Control TypePurposeExamination Focus
Order Size Limits Prevent inadvertent large orders Are limits appropriate for strategy and market?
Price Collars Block trades at prices far from market How are collar bands determined and updated?
Duplicate Order Prevention Avoid sending same order multiple times Testing of duplicate detection logic
Message Throttling Limit order message rates Compliance with exchange requirements
Kill Switch Immediately halt all automated trading Testing frequency and documented procedures

Document Requests for Algo Platforms

When the SEC examines an algorithmic trading platform, the document request list (DRL) will be significantly more detailed than for traditional advisers. Understanding what to expect helps me prepare in advance.

Source Code Requests

The SEC can and does request actual source code. While I can discuss proprietary concerns, outright refusal to produce code is not an option. I should be prepared to provide annotated code with explanations, potentially under confidentiality protections.

Algorithm Governance & Testing Review

The SEC expects algorithm governance to mirror the rigor applied to traditional investment processes - with additional controls given the speed and scale of automated systems.

Governance Framework Components

ComponentKey ElementsExamination Questions
Committee Structure Cross-functional team with authority over algorithms Who approves new algorithms? What are their qualifications?
Development Standards Coding standards, documentation requirements, peer review Show me your development standards document.
Testing Requirements Mandatory testing before production deployment What testing must occur before an algorithm goes live?
Change Management Approval process for modifications to existing algorithms How do you determine if a change is "material"?
Periodic Review Scheduled reassessment of algorithm appropriateness How often do you review each algorithm's performance?
Decommissioning Process for retiring underperforming algorithms When was the last time you retired an algorithm and why?

Testing Expectations

The SEC will scrutinize not just whether I tested, but how thoroughly and realistically.

Common Testing Deficiencies

  • Backtests run only on the same data used to train the model (data mining)
  • Unrealistic assumptions about execution (using closing prices, ignoring liquidity)
  • No stress testing or only testing in favorable market conditions
  • Cherry-picking test periods to show favorable results
  • No documentation of testing methodology or parameters used
  • Failure to update tests when market conditions change

Backtesting Documentation Requirements

Backtesting is where many algorithmic platforms stumble during examinations. The SEC views backtesting documentation as critical evidence of due diligence before deploying strategies on client assets.

What Must Be Documented

  1. Data Sources and Quality: Where did the historical data come from? Corporate actions adjusted? Survivorship bias addressed?
  2. Testing Period: Specific start and end dates, rationale for period selection
  3. Transaction Cost Assumptions: Commissions, spreads, market impact, slippage assumptions
  4. Rebalancing Frequency: How often the strategy trades in the backtest
  5. Constraints Applied: Position limits, sector limits, liquidity constraints
  6. Results: Full performance metrics including returns, volatility, drawdowns, Sharpe ratio
  7. Multiple Scenarios: Results under different market regimes and parameter settings
  8. Comparison to Benchmark: How the strategy performed vs. relevant benchmarks

Backtesting Best Practices

PracticeWhy It MattersHow the SEC Evaluates
Walk-Forward Analysis Prevents overfitting by testing on unseen data periods Are walk-forward results materially worse than in-sample?
Monte Carlo Simulation Assesses sensitivity to randomness and sequence of returns What's the distribution of potential outcomes?
Realistic Execution Ensures backtest reflects actual trading conditions Compare backtest assumptions to live trading costs
Documented Assumptions Transparency about what's built into results Can you defend every assumption in your backtest?
Version Control Track changes to strategy over time Show me backtests from when you first deployed vs. now

The "Curve Fitting" Problem

Examiners are trained to spot curve fitting - algorithms that are over-optimized to historical data and unlikely to perform out-of-sample. Warning signs include excessive parameters, perfect backtests, and lack of economic rationale for strategy behavior. If my backtest looks too good to be true, examiners will assume it is.

Performance Attribution Analysis

The SEC expects me to be able to explain where my algorithm-generated returns come from. Performance attribution demonstrates I understand my own strategies and can identify when they're not working as designed.

Attribution Components

Why Attribution Matters for Examinations

Exam QuestionWhat Attribution Shows
"Is your algorithm delivering the returns you promised?" Comparison of expected vs. actual performance sources
"Are you taking risks you disclosed to clients?" Risk factor exposures vs. Form ADV risk descriptions
"How do you know when your algorithm stops working?" Changes in attribution pattern signal strategy degradation
"Are your marketing claims accurate?" Attribution validates or contradicts marketing narratives

Proactive Attribution Review

Performing regular (monthly or quarterly) performance attribution and documenting findings demonstrates strong governance. If I can show examiners that I monitor attribution and adjust strategies when patterns change, this evidences good fiduciary practice.

Marketing & Advertising Review

The SEC has brought numerous enforcement actions against firms making misleading claims about algorithmic or AI capabilities. Marketing review is a critical exam focus area.

High-Risk Marketing Claims

Claims That Trigger SEC Scrutiny

  • "AI-Powered Investment Platform": Must demonstrate actual AI/ML, not just rules-based algorithms
  • "Outperform the Market": Requires substantiation and proper disclaimers
  • "Eliminate Human Emotion/Bias": Algorithms embed developer biases - this claim is often false
  • "Sophisticated Quantitative Models": Must match actual complexity of models used
  • "Proven Track Record": Performance must be calculated according to GIPS or with clear methodology
  • "Tax Optimization": Must actually implement tax-aware strategies, not just harvest losses

Marketing Documentation Required

SEC Marketing Rule (Rule 206(4)-1) Application

RequirementAlgorithm-Specific Consideration
General Prohibitions Cannot make untrue statements about algorithm capabilities or past performance
Performance Advertising Must present gross and net returns; backtests must be labeled as hypothetical
Third-Party Ratings If using algorithm ratings/rankings, must disclose methodology and conflicts
Testimonials/Endorsements Client testimonials about algorithm performance require disclosures and oversight
Predecessor Performance Can't claim current algorithm performance from prior similar strategies without meeting requirements

Social Media and Algorithmic Claims

Tweets, LinkedIn posts, and YouTube videos are advertising under SEC rules. If I or my team make claims about algorithm performance or capabilities on social media, those claims must be substantiated and compliant with advertising rules. Many enforcement actions arise from social media posts.

Cybersecurity & Data Protection Exam

Algorithmic trading platforms are high-value cybersecurity targets. The SEC's cybersecurity examination program focuses on both protecting client data and ensuring trading systems can't be compromised.

SEC Cybersecurity Examination Focus

CategoryExamination Questions
Governance Who is responsible for cybersecurity? How often does board/management review cyber risk?
Risk Assessment When did you last assess cyber risks? How do you identify critical systems?
Access Controls How do you control access to trading algorithms and client data?
Data Protection Is sensitive data encrypted at rest and in transit? How do you protect PII?
Incident Response Do you have a written incident response plan? When was it last tested?
Vendor Management How do you assess cybersecurity of third-party service providers?
Training What cybersecurity training do employees receive? How often?

Algorithm-Specific Cyber Considerations

Regulation S-P and Safeguards Rule

The SEC's Regulation S-P requires written policies to protect customer information. The recent Safeguards Rule amendments (effective June 2023) require specific controls including encryption, access controls, incident response plans, and annual risk assessments. These aren't optional - they're regulatory requirements.

Fiduciary Duty for AI Models

When my algorithm provides personalized investment advice, I owe clients a fiduciary duty - even though the advice comes from code, not humans. The SEC has made clear this duty is non-waivable and non-delegable.

How Fiduciary Duty Applies to Algorithms

Duty of Care

  • Adequate Basis: Algorithm must gather sufficient client information to make suitable recommendations
  • Reasonable Investigation: I must understand how the algorithm works and whether it's appropriate
  • Ongoing Monitoring: Duty continues after recommendation - I must monitor client accounts
  • Best Execution: If algorithm executes trades, must seek best execution

Duty of Loyalty

  • Client First: Algorithm must prioritize client interests over firm revenue
  • Conflict Disclosure: All conflicts embedded in algorithm design must be disclosed
  • No Self-Dealing: Algorithm can't favor proprietary products without disclosure and consent
  • Informed Consent: Clients must understand conflicts before agreeing to algo advice

Examination Questions on Fiduciary Compliance

The Questionnaire Problem

Many robo-advisers fail examinations due to inadequate intake questionnaires. If my questionnaire doesn't gather sufficient information about client financial situation, goals, risk tolerance, and experience, the algorithm cannot possibly provide suitable advice. Examiners will test whether my questionnaire meets fiduciary standards.

Conflicts Embedded in Algorithms

Conflict TypeExampleDisclosure/Mitigation Required
Revenue Optimization Algorithm designed to maximize platform fees Eliminate or obtain informed consent with full disclosure
Proprietary Products Algorithm favors firm's own ETFs or funds Disclose conflict; demonstrate suitability independent of conflict
Payment for Order Flow Execution venue selection influenced by PFOF Disclose arrangement; demonstrate best execution
Data Provider Incentives Compensation from data vendors whose info influences recommendations Disclose relationship and potential bias
Training Data Bias Model trained on data that favors certain strategies or products Disclose limitations and scenarios where model may underperform

Preparing for Your First Exam

If my algorithmic trading platform has never been examined, preparation is critical. First exams often result in more deficiency letters because firms haven't yet learned what the SEC expects.

Pre-Exam Readiness Checklist

  1. Document Inventory: Create comprehensive list of all algorithm-related documentation I have (and gaps)
  2. Mock Exam: Have counsel or consultants perform mock examination using sample DRL
  3. Form ADV Review: Ensure Form ADV accurately describes algorithm capabilities and limitations
  4. Marketing Audit: Review all marketing materials for unsupported claims
  5. Testing Documentation: Compile all backtesting, stress testing, validation reports
  6. Governance Review: Document governance structure and approval processes
  7. Code Documentation: Prepare annotated source code with explanations for non-technical reviewers
  8. Performance Substantiation: Prepare performance calculations with full methodology
  9. Conflict Assessment: Identify and document all potential conflicts
  10. Cybersecurity Documentation: Compile cyber policies, risk assessments, incident response plans

The 90-Day Head Start

Don't wait for an examination letter. I should prepare as if an exam could arrive tomorrow. Maintaining exam-ready documentation continuously is far easier than scrambling when the letter arrives. Most successful firms perform annual mock exams to identify gaps proactively.

Team Preparation

RolePreparation Focus
CCO (Chief Compliance Officer) Primary point of contact; understand entire compliance program and algorithm governance
CTO/Lead Developer Be prepared to explain algorithm design, testing, and technical architecture
Portfolio Managers Understand investment rationale, performance attribution, and strategy evolution
Legal Counsel Review all document productions; present for sensitive interviews; advise on exam strategy
Operations Staff Understand trade execution process, best execution analysis, broker selection

Interview Protocol Training

Before examiners arrive, I train all personnel who might be interviewed on proper protocol: answer only what's asked, don't speculate, say "I don't know" rather than guess, take notes on questions, and inform CCO of all examiner interactions. Poor interview performance can turn a routine exam into an enforcement referral.

Common First-Exam Deficiencies

Top Deficiencies at First Algo Platform Exams

  • Inadequate Documentation: No written algorithm specifications, testing records incomplete
  • Governance Gaps: No formal governance committee or approval process for algorithms
  • Form ADV Inaccuracies: Vague or outdated description of algorithmic services
  • Marketing Overstatements: Claims about AI/ML capabilities not matched by reality
  • Insufficient Testing: Backtests that don't cover multiple market regimes or stress scenarios
  • Conflict Disclosure Failures: Undisclosed conflicts in algorithm design or execution
  • Cybersecurity Deficiencies: No written cybersecurity policies or incident response plan
  • Best Execution Gaps: No systematic analysis of execution quality for automated trades
  • Questionnaire Inadequacy: Intake forms don't gather sufficient info for suitable advice
  • Books and Records: Incomplete records of algorithm changes, client communications

Remediation Strategies

If I receive a deficiency letter, how I respond determines whether the matter closes or escalates to enforcement.

Deficiency TypeEffective RemediationWhat Not To Do
Documentation Gaps Immediately create documentation going forward; reconstruct past docs where possible Create backdated documents - this is obstruction
Policy Deficiencies Adopt written policies; train staff; demonstrate implementation Adopt policies but not actually follow them
Testing Inadequacy Perform comprehensive testing now; adopt testing standards for future Argue that testing isn't necessary for my type of algorithm
Disclosure Failures Amend Form ADV immediately; communicate changes to clients Delay amendments or provide minimal disclosure
Conflicts Not Addressed Eliminate conflict, fully disclose, or obtain informed client consent Argue the conflict is immaterial without client perspective

The Remediation Response

My deficiency response should have three components: (1) acknowledgment of the finding, (2) explanation of what I've already done to address it, and (3) commitment to specific future actions with timeline. Attach evidence of remediation already completed. This demonstrates I take compliance seriously.
