  • What does "buy" mean in CSX activity?

    "Buy" means an investor increased their reported position in CSX compared to the prior reporting period. This reflects growing exposure to CSX CORP (CSX) rather than necessarily a brand-new position (though new positions also appear as buys when prior quantity was zero).
