Muhlenkamp & Company
Ron Muhlenkamp's value-equity firm, founded 1978, runs the Muhlenkamp Fund (MUHLX) from Wexford, Pennsylvania — screening for companies with ROE above 14%.
Muhlenkamp & Company
Ron Muhlenkamp founded the firm in 1978, carrying forward an investment discipline he began developing in 1968. The firm incorporated in Pennsylvania in 1981 and still operates from its Wexford headquarters, north of Pittsburgh. Muhlenkamp describes the practice as professional investment managers who sell no products and hold no broker affiliations — the only thing they get paid for, the firm states, is investing client money. The founding wealth origin is not publicly disclosed; the business has always been a registered investment adviser serving pension plans, profit-sharing plans, and individual accounts. The strategy is fundamentally bottom-up, value-driven, and benchmark-agnostic. Muhlenkamp screens domestic equities for companies with return on shareholder equity above 14% and a price-to-earnings ratio below or equal to that ROE, a relationship it adjusts for inflation and interest-rate climates. The resulting portfolio crosses all market capitalizations and typically holds 20 to 50 names. As of the March 2026 fact sheet, the top holdings included Agnico Eagle Mines, Newmont, Rush Enterprises, Royal Gold, EQT, McKesson, Berkshire Hathaway, SLB, Wabtec, and Apple. The firm reserves the right to own foreign equities when the potential return compensates for currency and political risk, but has rarely exceeded 10% international exposure. Bonds and cash enter the portfolio when equity screens produce too few candidates. Covered calls and straddles are used sparingly, capped at 5% of the portfolio, to supplement total returns. Muhlenkamp & Company is a compact operation built around a single in-house portfolio manager and dedicated trader. The firm does not disclose total assets under management or a team headcount; inquiries are directed to an SMA fact sheet. The Muhlenkamp Fund (MUHLX) reported a net asset value of $81.25 as of May 29, 2026, with a year-to-date return of 11.29%. In calendar year 2025, the fund distributed a long-term capital gain of $2.13 per share and an income dividend of $0.31 per share. The gross expense ratio on the fund is 1.28%. The firm does not disclose membership in peer clubs or adjacent philanthropic vehicles. The structural differentiator is Muhlenkamp's explicit refusal to use market capitalization as an organizing principle — a posture that has produced extreme style divergence over decades. The portfolio defied consensus during the 1998–2001 tech bubble, lagged during the 2010–2020 fad-driven markets, and then outperformed from 2021 through 2022. This pattern reflects a process built on ROE and P/E screens that the firm claims has remained unchanged for over 30 years, managed by a team whose investable assets are entirely managed in-house.

Frequently asked questions
Who makes investment decisions at Muhlenkamp & Company?
A single portfolio manager — historically the founder, Ron Muhlenkamp — makes all buy and sell decisions, placing trades through an in-house trader. The firm states that 100% of the portfolio manager's investable assets are managed by the firm itself, aligning personal and client outcomes.
What is Muhlenkamp's core investment screen?
The process starts with a bottom-up scan of most U.S. companies at least four times per year, screening for return on shareholder equity above 14% and a price-to-earnings ratio below or equal to that ROE. The required P/E threshold tightens or loosens depending on prevailing inflation and interest rates.
Does Muhlenkamp manage a mutual fund or only separate accounts?
The firm manages both. The flagship vehicle is the Muhlenkamp Fund (ticker MUHLX), a no-load mutual fund with a gross expense ratio of 1.28%. It also runs separately managed accounts; a dedicated SMA fact sheet details composite firm assets.
How concentrated is the Muhlenkamp Fund?
The fund limits individual positions to 5% of the portfolio at purchase and diversifies across at least 20 companies. Industry exposure is capped at 20%, though the firm defines sectors and industries by underlying business characteristics rather than standard GICS classifications.
How does Muhlenkamp define investment risk?
The firm explicitly rejects Wall Street's short-term price-volatility definition. Instead, it defines risk as the probability of losing purchasing power over long time periods, and benchmarks itself against an after-tax, after-inflation return of at least 5% annualized over any rolling three-year period.
Does the firm hold cash or bonds?
Yes, there is no policy requiring full equity investment. If the screening process yields fewer than 20 qualifying companies, the portfolio holds cash or fixed income for the balance. A severe climate change — such as depression conditions — could shift the entire portfolio to U.S. Treasury bonds.
In what market environments has Muhlenkamp historically outperformed or lagged?
The firm's own disclosure states it tends to outperform during tough, volatile, or pessimistic markets (1970s, 2000–2008, 2021–2022) and to underperform during fad-driven, consensus-optimistic markets (late 1990s, 2010–2020). This pattern stems from its refusal to abandon its ROE/P/E discipline.
