The near-total exit by Wasatch Advisors (a well-known active manager) is the dominant signal here, not the three small accumulators. Monitor upcoming 13F filings and OSK's next earnings report for fundamental deterioration that may have driven the selling. The 45-day reporting lag means this cluster may already be stale.
Executive Summary
Institutional activity in Oshkosh Corp (OSK) during Q3 2026 shows a sharp divergence: three small asset managers modestly accumulated positions totaling $1.7M, while two larger asset managers — Wasatch Advisors and Assenagon — aggressively exited, with Wasatch selling nearly 99% of its stake. The net dollar flow is heavily skewed toward selling (-$47.6M), suggesting a bearish institutional read on the stock despite the buyer count advantage.

- The three buyers are very small (combined $1.7M) and may represent index rebalancing or tax-loss harvesting, not conviction
