Comprehensive Analysis of SEC 13F Filing: M. Kraus & Co
Portfolio Overview

M. Kraus & Co has undergone a significant transformation in the quarter ending December 31, 2025. The firm executed a massive expansion strategy, increasing the total portfolio value by 217.6%, rising from $112.75M to $358.15M.

Key Holdings

The portfolio is currently led by a strong conviction in large-cap technology and industrial stalwarts. Microsoft Corp. (MSFT) is the dominant holding, accounting for 10.12% of the portfolio ($36.25M), making it the single largest concentration risk and opportunity. Alphabet Inc. Class C (GOOG) follows as the second-largest position at 8.91% ($31.90M). Notably, the firm holds both Class C and Class A shares of Alphabet, indicating a strong overall bet on the company.

The third-largest position, Berkshire Hathaway - B ($22.01M), suggests a tilt toward financial stability and a value-oriented approach. The top ten holdings are rounded out by high-quality industrial and healthcare names such as Thermo Fisher Scientific, RTX Corporation, and L3 Harris Technologies. Interestingly, Apple Inc. (AAPL) appears lower in the rankings at position 21, comprising only 2.03% of the portfolio. This underweighting relative to its market cap weight, combined with a similarly small position in NVIDIA (0.34%), signals that the firm is not chasing the highest-momentum momentum trades but is rather selecting specific quality names within the tech sector.
