What does "buy" mean in K4F activity?
"Buy" means an investor increased their reported position in K4F compared to the prior reporting period. This reflects growing exposure to ONESTREAM INC (K4F) rather than necessarily a brand-new position (though new positions also appear as buys when prior quantity was zero).
Is institutional interest in K4F increasing?
