What does "buy" mean in MMM activity?
"Buy" means an investor increased their reported position in MMM compared to the prior reporting period. This reflects growing exposure to 3M CO (MMM) rather than necessarily a brand-new position (though new positions also appear as buys when prior quantity was zero).
Is institutional interest in MMM 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.
