Comprehensive Analysis of Ipswich Investment Management Co., Inc. SEC 13F Filing
Portfolio Overview

Ipswich Investment Management Co., Inc. has reported a significant transformation in its portfolio for the period ending December 31, 2025. The total portfolio value surged by 157.0%, increasing from $168.06 million in the prior quarter to $431.84 million. This dramatic appreciation is likely driven by a combination of strong market performance in underlying assets and substantial capital in...

The portfolio currently consists of 185 positions. Despite the increase in asset base, the manager maintains a relatively diversified approach, though with a clear concentration in top-tier names. The top 10 holdings account for approximately 31.7% of the total portfolio value. The data indicates a high turnover strategy this quarter, characterized by aggressive rotation: the firm initiated 31 new positions and completely exited 31 positions, while only 6 stakes were increased and 13 were reduced. This suggests a tactical reallocation rather than a passive buy-and-hold philosophy.

Key Holdings

The portfolio is heavily anchored in large-cap technology and blue-chip growth stocks, with a distinct tilt toward market leaders.
