Frequently asked questions about APH activity

  • Which institutional owners are buying APH?

    Institutional owners buying APH include investors who have either initiated new positions or increased their existing holdings based on recent SEC 13F filings. The activity table above highlights which funds added shares in the latest reporting periods and how their positions changed over time.

  • What does "buy" mean in APH activity?

    "Buy" means an investor increased their reported position in APH compared to the prior reporting period. This reflects growing exposure to AMPHENOL CORP-CL A (APH) rather than necessarily a brand-new position (though new positions also appear as buys when prior quantity was zero).

  • Is institutional interest in APH increasing?
