Frequently asked questions about GHC activity

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 GHC activity?

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

  • Is institutional interest in GHC increasing?
