    Institutional owners buying OGN 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 OGN activity?

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

  • Is institutional interest in OGN increasing?
