Frequently asked questions about KROS activity

  • Which institutional owners are buying KROS?

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 KROS activity?

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

  • Is institutional interest in KROS increasing?

    Institutional interest in KROS can be assessed by comparing the number of tracked funds adding or increasing positions versus those trimming or exiting across the periods shown. A higher number of additions typically signals increasing participation among large filers, but it should be read alongside position sizes and the full table.
