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