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