Introduction
Dietz Asset Management is a private investment management firm headquartered in New York City, United States. Established in the early 1990s, the company has developed a reputation for disciplined equity selection and a focus on value investing principles. Its portfolio management team typically oversees a range of funds that include mutual funds, separately managed accounts, and institutional offerings. Dietz Asset Management emphasizes rigorous fundamental analysis, long‑term investment horizons, and a culture of independent thinking.
History and Background
Founding and Early Years
The firm was founded in 1992 by Thomas Dietz, a former analyst at a major Wall Street research firm. At its inception, Dietz Asset Management operated as a boutique advisory service catering primarily to high net‑worth individuals and family offices. The early strategy centered on a systematic approach to identifying undervalued growth stocks within technology and healthcare sectors.
Expansion of Product Offerings
By the late 1990s, the company had launched its first publicly traded fund, the Dietz Growth Equity Fund, which attracted approximately $120 million in assets under management (AUM). The fund's success allowed Dietz Asset Management to broaden its product suite to include fixed‑income and multi‑asset solutions. In 2004, the firm opened a secondary office in Chicago, which served as a regional hub for institutional sales and client servicing.
Modernization and Technological Integration
During the 2010s, Dietz Asset Management invested in advanced data analytics platforms and artificial intelligence tools to enhance its research processes. The firm adopted a cloud‑based portfolio management system in 2016, enabling real‑time risk monitoring and automated compliance checks. This modernization effort coincided with a strategic shift toward environmental, social, and governance (ESG) integration across all investment strategies.
Corporate Structure
Ownership and Governance
The company remains privately held, with Thomas Dietz retaining majority ownership. The board of directors consists of industry veterans and former senior executives from large asset management firms. Governance policies emphasize transparency, fiduciary responsibility, and alignment of interests between employees and clients.
Employee Composition
As of 2025, Dietz Asset Management employs roughly 80 staff members, including portfolio managers, analysts, compliance officers, and client service representatives. The firm maintains a low staff‑to‑client ratio, which supports personalized advisory relationships. Compensation packages for portfolio managers blend base salary with performance‑based incentives tied to fund returns and risk‑adjusted metrics.
Investment Philosophy
Fundamental Analysis and Value Orientation
Dietz Asset Management adopts a fundamentally driven investment process. The research team evaluates companies based on financial statements, competitive positioning, management quality, and growth prospects. A key tenet of the philosophy is the identification of “margin of safety” in valuation, which serves as a buffer against market volatility.
Long‑Term Horizon and Patience
The firm emphasizes a buy‑and‑hold strategy, with portfolio holding periods typically exceeding five years. Short‑term market fluctuations are regarded as noise, and decisions are driven by long‑term economic and business fundamentals rather than cyclical market sentiment.
Risk Management and Diversification
Risk control is integral to the firm's methodology. Position sizing is determined through a combination of volatility targeting and scenario analysis. Diversification across sectors, geographies, and market caps is maintained to mitigate concentration risk. The firm employs both quantitative stress testing and qualitative risk assessments to anticipate potential downside events.
Product Lineup
Equity Funds
The Dietz Growth Equity Fund, launched in 1998, focuses on mid‑cap technology and healthcare companies. A second equity vehicle, the Dietz Value Equity Fund, targets large‑cap firms with attractive valuations and strong dividend histories. Both funds are managed with an active style but maintain low turnover relative to peer indices.
Fixed‑Income Offerings
Dietz Asset Management offers a range of fixed‑income funds, including a high‑yield corporate bond fund and a municipal bond fund designed for tax‑exempt income. These funds aim to provide income streams while preserving capital through diversification across credit ratings and maturities.
Multi‑Asset Solutions
The firm provides multi‑asset portfolios that blend equity, fixed‑income, and alternative strategies. These solutions are tailored to institutional investors and high net‑worth individuals seeking a single vehicle for comprehensive risk‑return management. The multi‑asset approach leverages rebalancing strategies to maintain target asset allocation profiles over time.
Separately Managed Accounts
For institutional clients, Dietz Asset Management offers separately managed accounts that allow for customized portfolio construction within the framework of the firm’s investment philosophy. These accounts provide transparency in holdings, performance, and fee structures, which is particularly attractive to asset‑owner institutions with stringent governance requirements.
