Comprehensive Analysis of SEC 13F Filing: Congress Asset Management Co

1. Portfolio Overview

Congress Asset Management Co. has reported a significant expansion in its portfolio management scope for the quarter ending December 31, 2025. The total portfolio value surged by 100.0%, growing from $7.10 billion to $14.21 billion. While this exact doubling suggests a substantial influx of new capital or a shift in reporting scope, the accompanying turnover data indicates a major strategic piv...

The portfolio remains highly diversified, comprising 381 total holdings. However, the firm executed a high level of churn this quarter. The filing data reveals a dynamic restructuring: 27 new positions were established, 27 positions were completely sold off, and 15 existing positions were reduced, with only 8 seeing increases. This level of activity indicates a tactical reallocation of assets, moving away from specific sub-sectors (particularly in software and smaller-cap tech) to establish a core position in large-cap growth leaders.

2. Key Holdings

The composition of the top 50 holdings reflects a "Barbell" strategy, balancing mega-cap technology stalwarts with high-conviction mid-cap growth and industrial names.
