Bruce & Co Q1 2026 13F Holdings and Activity Report

I. Institutional Overview

The institutional portrait of Bruce & Co is one of remarkable patience and concentrated discipline. With only 41 stocks in the entire portfolio, the firm clearly eschews the "index-hugging" or hyper-diversified strategies common among larger institutions. Instead, Robert Bruce operates with a philosophy that suggests every position must earn its place through rigorous fundamental merit. A significant portion of the portfolio is comprised of holdings that have been maintained for over a decade, such as NextEra Energy, AbbVie, and The Allstate Corporation. This "buy and hold" mentality is a testament to a low-turnover strategy, where the institution acts more like a part-owner of businesses rather than a mere trader of tickers.

II. Sector Allocation Analysis

The third-largest allocation is to Industrials at 17.79%. This is a significant weight that provides a necessary counterweight to the purely defensive nature of Healthcare and Utilities. The industrial holdings in this portfolio, such as AerCap Holdings and U-Haul Holding Company, represent a bet on the "physical economy." AerCap, as a leader in aviation leasing, is a direct play on the long-term recovery and growth of global air travel. U-Haul represents the logistical backbone of domestic mobility. This allocation suggests that while the firm is cautious, it still sees significant value in companies that own and manage essential physical infrastructure and assets.

III. Top 10 Holdings Deep Dive

This quarter, the institution reduced its share count by 3.22%. Given the long-term nature of this holding, such a small reduction should be viewed as tactical rebalancing rather than a shift in fundamental belief. Interestingly, despite the slight reduction in shares, the portfolio weight actually increased from 7.72% to 7.98%. This indicates that NextEra’s stock price outperformed the rest of the portfolio during the quarter, naturally pushing its weight higher. The motivation for holding NEE is clear: it provides a reliable dividend, a regulated earnings base, and a significant tailwind from the global transition to clean energy. For Bruce & Co, NEE is the ultimate "sleep well at night" stock that offers both safety and a moderate growth kicker.

IV. Major Buys/Additions

The motivation for this "New Buy" appears to be a "growth acceleration bet" within the firm's favored Healthcare sector. Unlike the large-cap pharmaceutical plays like AbbVie or Merck, Beta Bionics represents a more specialized, technology-driven approach to a chronic health condition. By taking a 1.58% position, Bruce & Co is signaling that they believe the company has reached a valuation trough or a commercial inflection point. The iLet system addresses a massive and growing market, and the institution is likely betting on the company's ability to disrupt the traditional insulin pump market. This move shows that while Bruce & Co is defensive, they are willing to take calculated risks on innovative companies that solve fundamental human problems.

The decision to add to this position suggests a bullish outlook on the company’s fundamental breakout. Supernus has been working to diversify its revenue stream beyond its legacy products, and the institution likely sees the current valuation as an attractive entry point for further accumulation. The CNS market is characterized by high patient loyalty and significant barriers to entry, providing the kind of "moat" that Bruce & Co prizes. This addition reinforces the firm's strategy of concentrating capital in its most trusted healthcare names.

V. Major Reductions and Rebalancing Operations

The motivation here likely stems from a combination of valuation concerns and a shift in the competitive landscape. Vicor operates in the high-tech power space, which is often subject to intense cyclicality and rapid technological shifts. By reducing the position by nearly 30%, Bruce & Co is signaling a decrease in confidence regarding the stock's near-term upside or a desire to reduce the portfolio's overall "beta" (volatility). Given that the technology sector is a very small part of the overall Bruce & Co strategy, this reduction suggests they are becoming even more selective within the tech space, moving capital away from high-multiple components and toward more stable, cash-flow-positive areas.

VI. Investment Insights and Risk Warnings

For retail investors, the reference value of Bruce & Co’s behavior lies in their patience and discipline . In a market often obsessed with the next AI breakthrough, Robert Bruce reminds us of the power of holding essential service companies for decades. However, his willingness to trim these positions to fund new ideas shows that "buy and hold" does not mean "buy and forget." Active rebalancing is a crucial tool for managing risk and ensuring that a portfolio stays aligned with the best available opportunities.
