Client Due Diligence Questionnaire (DDQ) Guide: Answering Quantitative Factor Questions

The Rigor of Institutional Due Diligence Questionnaires

As institutional allocators, consultants, and family office investment committees evaluate quantitative asset managers, the Due Diligence Questionnaire (DDQ) serves as the primary governance audit. Allocators look far beyond marketing pitch decks and annualized historical returns; they scrutinize model design, data integrity, risk management frameworks, and compliance controls.

For quantitative RIA principals and SMA portfolio managers, providing transparent, rigorous answers to technical DDQ inquiries is essential for winning and retaining institutional mandates.

Core Factor Governance Dimensions in DDQ Reviews

Institutional DDQs typically focus on four fundamental operational and quantitative areas:

• Factor Definition and Construction: Allocators probe whether factor scores derive from economically grounded fundamental ratios or opaque black-box models. Managers must articulate exact metric formulations—such as operating cash flow yield, return on invested capital, and price momentum—and explain cross-sectional normalization techniques (e.g., z-scoring and sector neutralization).
• Data Provenance and Bias Mitigation: Institutional fiduciaries require detailed verification that historical backtests eliminate survivorship bias, delisting return distortions, and look-ahead bias through point-in-time database architectures.
• Turnover and Real-World Friction: DDQs evaluate how managers control transaction costs, liquidity constraints, and rebalance turnover, requiring documentation of trade hold-buffers and capacity ceilings.
• Regulatory Compliance and the SEC Marketing Rule: Managers must demonstrate adherence to SEC Investment Advisers Act Rule 206(4)-1 (Release No. IA-5653). Under the Marketing Rule, all performance presentations and quantitative metrics must provide fair, balanced disclosures, net-of-fee reporting where required, and transparent descriptions of model assumptions and limitations.

Documenting Institutional Governance with Parallax

Quantitative managers streamline DDQ compliance by grounding operational documentation in verified quantitative frameworks. Managers document objective factor scoring methodologies using the Parallax Factor Scoring Methodology and align regulatory disclosures with institutional standards outlined in Parallax Legal Disclaimers. Investment advisers remain solely responsible for their own regulatory filings, marketing compliance, and client disclosures.
