Tandem Investment Advisors
Tandem Investment Advisors was founded in 1990 by John B. Carew at Tandem Farm in Charlottesville, Virginia, before relocating headquarters to Charleston, South Carolina in 2007. The firm remains tightly controlled by Carew and two long-tenured partners: Co-CIO and CFO William L. Little, Jr. (27% owner) and Co-CIO Benjamin G. Carew (9% owner), a family member. The ownership structure concentrates decision-making among three individuals who have operated the same quantitative discipline for more than three decades. Tandem runs three long-only US equity strategies — Large Cap Core, Mid Cap Core, and a broad Equity Strategy — built on a proprietary ratio that screens over 3,000 stocks for mean-reversion signals. The firm does not drift into venture, private equity, or alternative structures; it executes a strictly quantitative process with five defined actions per holding: Buy, Add, Hold, Trim, or Liquidate. Tandem's 1,000-plus financial advisor partners distribute the strategies through separately managed accounts, with the firm willing to hold cash when its ratio finds no attractively valued entry points. The concentrated approach targets businesses with consistent fundamental growth through any economic environment, with an emphasis on dividend growers and competitively advantaged management teams. Tandem surpassed $3 billion in assets under management in 2023 — a threshold reached with a lean team that publishes its own trading-desk commentary and partners directly with the CFA Society South Carolina, where Billy Little is a past president. John Carew serves as Vice Chair of the College of Charleston School of Business Investment Program, reinforcing a local professional network but revealing no additional office locations. The firm's philanthropic footprint includes the Brain & Behavior Research Foundation and the College of Charleston Foundation. In 2023, Tandem crossed the $3 billion AUM milestone, continuing a growth trajectory that saw the firm double from $1 billion in 2020 (per firm website, 2023). Tandem's structural differentiator is a decision architecture that bans discretionary overrides. The three-person investment team — Carew, Little, and Carew — reviews the outputs of a proprietary ratio computation and implements signals. No fundamental analyst layer sits between the math and the trade, making this an intentionally small, owner-operated process designed for one outcome: a low-volatility core equity sleeve that financial advisors can hold through drawdowns.

Frequently asked questions
Who makes investment decisions at Tandem?
The three-person Investment Team — John B. Carew (President and CEO), William L. Little, Jr. (Co-CIO and CFO), and Benjamin G. Carew (Co-CIO) — collectively reviews the output of Tandem's proprietary quantitative ratio and implements action. Decisions follow a strict five-action discipline: Buy, Add, Hold, Trim, or Liquidate. The process is designed to exclude discretionary overrides.
How does Tandem's proprietary investment process work?
Tandem screens over 3,000 US equities with a proprietary ratio that identifies deviations from a stock's historical mean — a mean-reversion signal that indicates attractive entry or exit points. The process has three sequential steps: a quantitative screen, a semi-quantitative review to verify data accuracy, and human implementation by the Investment Team (per the firm). When few buying opportunities exist, Tandem will hold cash rather than force deployment into overvalued names.
Does Tandem participate in fund commitments or only manage separate accounts?
Tandem operates exclusively as a long-only US equity manager distributing its strategies through separately managed accounts (SMAs) to more than 1,000 financial advisor partners. The firm does not manage commingled vehicles or fund structures. Its investment discipline remains confined to public equities across Large Cap Core, Mid Cap Core, and a broader Equity Strategy.
How is Tandem's ownership structured?
Tandem is tightly held by three individuals: John B. Carew owns 59%, William L. Little, Jr. holds 27%, and Benjamin G. Carew — a family member of John Carew — holds 9%. Additional family members own the remaining 5% in minority stakes. This ownership concentration puts strategic control with the same three people who run the investment process day-to-day.
What is Tandem's posture on portfolio volatility and downside capture?
Tandem explicitly targets low volatility of returns and low downside capture versus the broad US equity market. The firm states it aims to deliver a more consistent, repeatable and less volatile experience than the market (per the firm). The willingness to hold cash when its quantitative ratio finds no attractively valued stocks is a core feature of this posture.
Does Tandem maintain philanthropic or community investment structures?
Tandem's principals support the Brain & Behavior Research Foundation and the College of Charleston Foundation. John Carew serves as Vice Chair of the College of Charleston School of Business Investment Program, and Billy Little is a past president of the CFA Society South Carolina. The firm does not list a separate foundation vehicle, operating philanthropic activity through personal principal involvement.
Where does Tandem's name originate?
Tandem was founded in 1990 at Tandem Farm in Charlottesville, Virginia, giving the firm its name (per the firm). The headquarters later moved to Charleston, South Carolina in 2007, where the firm remains based.
