One Oak Capital Management: Building Trust Through Transparency

Published on:
April 15, 2026

When you hand your capital to a fixed income adviser, you are making a decision based on trust. You need to know how your money is being managed, what risks your portfolio carries, and how your adviser makes investment decisions. Trust is not built through marketing language. It is built through consistent, verifiable transparency.

One Oak Capital Management, LLC has operated as a Purchase, New York-based SEC-registered investment adviser since 2013. From the firm's founding, transparency has been a structural feature of how it operates, not an afterthought. The firm's approach to client communication, performance reporting, and risk disclosure reflects this commitment at every level.


What Transparency Means at One Oak Capital Management

Transparency at One Oak Capital Management, LLC means giving you the information you need to evaluate your investment, make informed decisions, and hold the firm accountable for results.

This starts with how the firm presents its own performance. The net return figures displayed publicly on the One Oak website reflect real-world results after fees. Specifically, net returns are calculated by deducting the firm's highest standard management fee of 0.30% per year from gross returns on a quarterly basis. You see exactly what fee is applied and how it affects performance. There is no ambiguity.

The firm also discloses that net returns do not include additional intermediary fees that may be charged by a client's custodian or platform. This level of fee clarity is something many investors never receive from their advisers.

Transparency also means disclosing what the firm does not know. One Oak states clearly that past performance is not representative of future results, and that actual performance may differ from composite returns depending on account size, investment guidelines, and inception date. This is honest disclosure. It protects you from forming unrealistic expectations.

How the Firm Communicates Performance and Decisions

One Oak Capital Management, LLC makes current performance data publicly accessible. The homepage displays 1-year, 3-year, 5-year, and inception-to-date annualized net returns for each separately managed account strategy. You do not need to request this information. It is available before you ever become a client.

The firm's investment professionals provide quarterly market commentary combined with insights on portfolio construction. This gives you a regular, structured window into how the team is reading markets and how those views are shaping portfolio decisions. You are not left waiting for an annual letter. You receive substantive updates each quarter, written by the same professionals who manage your capital.

One Oak also uses professional-grade analytics tools to support its investment process. The firm uses Bloomberg and Fabkom alongside research from multiple sell-side firms. When the firm makes a portfolio decision, it is supported by institutional-quality data. You benefit from that analytical rigor when it is time to explain what drove a specific trade or allocation.


The Role of GIPS Compliance in Reporting

One Oak Capital Management, LLC claims compliance with the Global Investment Performance Standards (GIPS) and has prepared and presented its performance reports in compliance with those standards. The firm has been independently verified for the periods 2019 through 2022.

GIPS is not a marketing label. It is a globally recognized framework that governs how investment performance is calculated, presented, and audited. When a firm is GIPS-compliant and independently verified, you know that the numbers have been reviewed by a third party. No self-reported performance data goes unchecked.

For you as an investor, GIPS compliance means the performance figures you see are calculated on a consistent, standardized basis. You can compare One Oak's results to other GIPS-compliant managers with confidence that the methodology is the same.


What Information Clients Receive About Their Investments

Separately managed accounts, the structure One Oak uses for its Enhanced Municipal Portfolio, Enhanced Taxable Municipal Portfolio, and Enhanced Short-Duration Municipal Portfolio, are inherently transparent investment vehicles. Unlike a mutual fund, where your capital is pooled with thousands of other investors, a separately managed account holds individual securities in your name. You can see every bond in your portfolio at any time. There is no black box.

This structure gives you direct visibility into what you own, what each security is rated, how much of the portfolio sits in any single sector, and what the overall duration of the portfolio is. You do not have to rely on a fund manager's description of what they are doing. You can verify it directly.

The firm's risk management framework adds another layer of disclosure. One Oak assesses six specific risk factors across every portfolio: interest rate risk, credit risk, liquidity risk, yield curve risk, sector risk, and regulatory risk. Each factor is actively monitored and managed. The firm describes this process publicly so you understand the criteria being applied to protect your capital. You know what the team is watching and why it matters.


How Transparency Strengthens Long-Term Client Relationships

Investment relationships break down when clients feel uninformed. When markets move against a portfolio and a client has no context for why, the natural response is doubt. Clear, consistent communication prevents that.

When One Oak provides quarterly commentary, it is not simply reporting numbers. It is explaining the environment those numbers reflect. A client who understands why interest rate duration was shortened, or why sector exposure shifted, is a client who can evaluate the decision rather than simply react to the result.

The firm's leadership team brings substantial combined experience to this communication responsibility. CEO and Chief Investment Officer Stephen DiTursi has 40 years of industry experience. Senior Portfolio Manager Neil Crabb has 34 years, and CFO and Chief Compliance Officer Joanne Costantini brings 30 years of experience managing relationships with regulatory and compliance bodies. When communication comes from professionals with this depth of experience, it carries credibility. You are not receiving a form letter. You are receiving perspective from people who have managed fixed income portfolios through multiple market cycles.

Joseph Marren, Head of Research at One Oak Capital Management, LLC, brings 49 years of industry experience, including senior roles at major financial institutions. His oversight of the firm's research strategy across all sectors reinforces the quality of the analysis that informs both portfolio decisions and client reporting.

Consistent transparency also builds accountability. When a firm discloses its process, its risk framework, and its performance calculation methodology, it is creating a standard against which it can be evaluated. One Oak accepts that accountability by making this information available publicly.


How One Oak's Approach Differs

Many investment managers present polished performance summaries with minimal context. They report numbers without explaining methodology, and they disclose fees in ways that require careful reading to interpret. Clients are often left trying to calculate what they are actually paying and what returns they are actually receiving after costs.

One Oak Capital Management, LLC takes a different approach. Performance is presented in net terms using the firm's highest standard fee, so there is no optimistic gross figure to mentally adjust. GIPS compliance means the calculation methodology has been independently reviewed. The separately managed account structure means you can see every position. The six-factor risk management framework is documented and publicly described. Quarterly market commentary gives you regular insight into how the team is thinking.

The firm also holds third-party recognition for results, not just for process. The Enhanced Municipal Portfolio earned Zephyr's PSN Top Gun award for a top 10 return for the three-year period ending December 31, 2025, in the PSN Municipal Universe. The Enhanced Taxable Municipal Portfolio earned PSN Top Gun awards for top 10 returns across the one-year, three-year, and quarterly periods ending December 31, 2025, in both the PSN Municipal Universe and the PSN Intermediate Maturity Universe. Both strategies carry Morningstar ratings. These external validations reinforce what the firm communicates directly.

Transparency is not a feature One Oak turns on for prospective clients. It is the consistent operating standard of the firm.
