Frequently asked questions about CCCC activity

  • Which institutional owners are buying CCCC?

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 CCCC activity?

    "Buy" means an investor increased their reported position in CCCC compared to the prior reporting period. This reflects growing exposure to C4 THERAPEUTICS INC (CCCC) rather than necessarily a brand-new position (though new positions also appear as buys when prior quantity was zero).

  • Is institutional interest in CCCC increasing?
