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

A higher number of additions typically signals increasing participation among large filers, but it should be read alongside position sizes and the full table.
