Muhlenkamp & Co

#### I. Institutional Overview The 13F filing for the fourth quarter of 2025 provides a transparent window into the investment operations of **Ronald Muhlenkamp - Muhlenkamp & Co**, a firm long recognized for its disciplined adherence to value-oriented investment principles. As of December 31, 2025, the firm’s reported portfolio value stood at **$371,820,349**, managing a highly curated selection of **28 stocks**. This snapshot reveals an institution that prioritizes depth over breadth, maintaining a concentrated portfolio that reflects high-conviction bets on specific macroeconomic themes and individual company fundamentals. To understand the psychological portrait of Muhlenkamp & Co., one must first look at the scale and structure of its holdings. With a portfolio value of approximately **$371.82 million**, Muhlenkamp operates as a boutique investment manager. Unlike "mega-funds" that manage hundreds of billions and are often forced into over-diversification due to liquidity constraints, Muhlenkamp’s scale allows for a "best ideas" approach. The fact that the firm holds only 28 positions is a definitive signal of an **active management philosophy**. In an era where many institutional investors have become "closet indexers," Muhlenkamp’s concentration suggests a willingness to deviate significantly from benchmark weights to pursue alpha. A portfolio of fewer than 30 stocks implies that each position must undergo rigorous scrutiny; there is no room for "filler" stocks. Every holding is expected to contribute meaningfully to the total return, and the risk is managed through deep fundamental understanding rather than broad-based statistical diversification. The scale trend for Muhlenkamp & Co. appears stable, with the firm maintaining its focus on mid-to-large cap equities that offer a blend of value and growth potential. The investment style, while not explicitly labeled in the metadata, is clearly discernible through the data: it is a **Value-Growth Hybrid** approach, often referred to as "Growth at a Reasonable Price" (GARP), but with a heavy emphasis on "Business Cycle" investing. Ronald Muhlenkamp has historically been vocal about his investment philosophy, which centers on Return on Equity (ROE) and the relationship between inflation, interest rates, and stock valuations. The Q4 2025 data reinforces this, showing a portfolio heavily weighted toward tangible assets and companies with strong pricing power. A key takeaway from the institutional portrait is the **longevity of holdings**. Many of the positions, such as **RUSHA (Rush Enterprises)**, **AAPL (Apple)**, and **MSFT (Microsoft)**, have been in the portfolio for over a decade. This indicates a "low-turnover" strategy where the institution acts as a long-term owner of businesses rather than a frequent trader of tickers. This "patient capital" approach is a hallmark of the Muhlenkamp methodology. However, the firm is not static. The Q4 report shows a strategic "slimming" of the portfolio, evidenced by the complete exit of three positions, including a significant stake in **JD (JD.com)**. This suggests a tactical pivot—moving away from certain international exposures and discretionary risks toward more defensive or cyclical domestic opportunities. In summary, the psychological portrait of Muhlenkamp & Co. in Q4 2025 is one of **calculated conviction and disciplined value-hunting**. The institution is currently positioned with a "hard asset" tilt, favoring materials and energy, while maintaining a core of high-quality technology and financial names. The contraction in the number of holdings from the previous period (implied by the exits) suggests a move toward even higher concentration, perhaps in anticipation of increased market volatility or a specific phase of the economic cycle where only the strongest "conviction" ideas are expected to thrive. #### II. Sector Allocation Analysis The sector allocation of Muhlenkamp & Co. in Q4 2025 serves as a macro-signal for the firm’s outlook on the economy, inflation, and the commodity cycle. By analyzing the distribution of the **$371.82 million** AUM across various industries, we can infer the institution’s strategic priorities. | Sector | Weight (%) | Trend/Sentiment | | :--- | :--- | :--- | | **Materials** | 27.56 | Heavy Overweight / Inflation Hedge | | **Financials** | 15.79 | Core Allocation / Interest Rate Play | | **Industrials** | 14.58 | Cyclical Growth / Infrastructure | | **Technology** | 12.96 | Quality Growth / Core Holding | | **Energy** | 10.53 | Tactical Overweight / Commodity Play | | **Healthcare** | 10.08 | Defensive Value | | **Consumer Discretionary** | 8.49 | Selective Exposure | | **Others** | 0.01 | Residual | **2.1 Concentration and Macro Judgment** The most striking feature of the sector allocation is the massive concentration in **Materials (27.56%)**. When combined with **Energy (10.53%)**, nearly **38%** of the portfolio is tied to basic resources and commodities. This is a profound macro statement. Typically, such a heavy weighting in Materials—specifically gold miners like **NEM (Newmont)** and **AEM (Agnico Eagle)**—suggests a defensive posture against currency debasement or a hedge against persistent inflation. It indicates that Muhlenkamp views "hard assets" as the superior risk-adjusted play in the current environment. The top three sectors—Materials, Financials, and Industrials—account for **57.93%** of the total portfolio. This concentration reflects a "pro-cyclical" yet "value-conscious" stance. While Materials provide an inflation hedge, the **15.79%** allocation to **Financials** suggests a belief in the stability of the banking and insurance sectors, likely benefiting from a "higher-for-longer" interest rate environment which aids net interest margins for banks and investment income for insurers like **NMIH (NMI Holdings)** and **BRK.B (Berkshire Hathaway)**. **2.2 Sector Rotation and Industry Insights** The allocation to **Industrials (14.58%)** is another pillar of the portfolio. This sector is represented by companies like **MTZ (MasTec)** and **WAB (Wabtec)**, which are deeply integrated into the "real economy"—infrastructure, telecommunications, and rail. The steady weight in these names suggests that Muhlenkamp is betting on the continued "re-industrialization" of the domestic economy and the long-term demand for infrastructure upgrades. In contrast, the **Technology** sector, at **12.96%**, is significant but not dominant. This is a notable departure from many modern institutional portfolios that are often 30-40% weighted in tech. Muhlenkamp’s tech exposure is concentrated in "cash-flow kings" like **MSFT (Microsoft)** and **AAPL (Apple)**, rather than speculative, high-multiple software-as-a-service (SaaS) companies. This reflects a preference for quality and valuation over pure momentum. The **Energy** sector (10.53%) remains a core component, primarily through **EQT (EQT Corporation)** and **SLB (Schlumberger)**. This suggests a belief that the energy transition will be a long, capital-intensive process where traditional fossil fuels and energy services remain essential and undervalued. **2.3 Inferred Economic Outlook** Based on this allocation, we can infer that Muhlenkamp & Co. is preparing for an economic environment characterized by: 1. **Sticky Inflation**: The heavy Materials and Energy tilt is the classic playbook for an inflationary regime. 2. **Resilient Domestic Growth**: The Industrials and Financials exposure suggests they do not anticipate a severe recession, but rather a period where companies with tangible assets and strong balance sheets outperform. 3. **Valuation Sensitivity**: The underweighting of high-growth tech (relative to the S&P 500) and the exit from international discretionary names like **JD** indicate a retreat from "expensive" or "high-uncertainty" growth toward "certainty of cash flow." The overall strategy appears to be a shift from "Growth" to "Value and Hard Assets." By focusing on sectors that produce essential goods (energy, gold, infrastructure) and services (financials, healthcare), the institution is building a "fortress portfolio" designed to withstand macro shocks while capturing upside from commodity cycles. #### III.
