Comprehensive Analysis of SEC 13F Filing: Auto-Owners Insurance Co

1. Portfolio Overview

Auto-Owners Insurance Co reported a significant transformation in its investment portfolio for the period ending September 30, 2025.

Despite the reduction in size, the portfolio remains diversified with 74 total holdings. However, the composition has shifted heavily toward a "core and satellite" structure, with a massive concentration in passive index instruments. The management activity level was exceptionally high this quarter, characterized by 32 complete exits and 23 new positions, with zero positions being increased. This indicates a complete overhaul of the portfolio's tactical allocations rather than mere trimming.

2. Key Holdings

The portfolio is dominated by Exchange Traded Funds (ETFs), which account for the top three positions and roughly 78% of the total portfolio value.
