The absence of institutional selling and the entry of a major sovereign wealth fund suggest strong underlying demand. Traders should monitor for follow-on buying and potential upward pressure on the stock, especially if active managers begin to join the trend.
Executive Summary
Three major institutions — Fidelity, Norges Bank, and Two Sigma — significantly increased their positions in Thermo Fisher Scientific during 2025-Q4, collectively adding $5.07 billion in new holdings with no notable selling. The cluster is driven by a mix of passive, sovereign, and quant investors, indicating broad-based confidence in the stock.
