  • What does "buy" mean in OXY activity?

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