Institutional investors reshuffle holdings

In early August 2026, 13F filings showed a wave of portfolio adjustments by large institutional investors across several U.S.-listed companies. The Healthcare of Ontario Pension Plan Trust Fund sharply reduced its stake in Avient Corporation, selling more than 80% of its holdings, while other pension funds and retirement systems increased their positions in the same company. At the same time, Segall Bryant & Hamill and other investors boosted their ownership in Avista Corporation.

Separate filings revealed that Militia Capital Management opened a new position in Saia Inc., and a group of funds, including AQR Capital Management and the California Public Employees Retirement System, altered their holdings in the logistics firm. Sapient Capital and several other investors also purchased sizable blocks of Hesai Group ADR shares, indicating continued interest in lidar and autonomous‑vehicle technology companies.

Together, these disclosures illustrate a broader pattern of institutional investors trimming, expanding, or initiating stakes in diverse sectors such as chemicals, utilities, transportation, and advanced sensing, reflecting ongoing strategic reallocation of capital.
