  • What does "buy" mean in EXAS activity?

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