In late July, filings showed several large investors expanding their positions in Belden Inc. and Bandwidth Inc., with Principal Financial Group and others raising stakes and institutional ownership reaching roughly 99% of Belden and 68% of Bandwidth. A week later, a similar pattern of portfolio rebalancing was reported for Construction Partners, Inc. Principal Financial Group trimmed its holding, while Dimensional Fund Advisors and other firms added shares, leaving institutional ownership at about 95%. Across both periods, hedge funds and asset managers continued to fine‑tune their U.S. equity portfolios, alternating between increases and reductions depending on the company, but maintaining dominant control of the stocks involved.
