Frequently asked questions about CMCSA activity
Which institutional owners are buying CMCSA?

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