  • What does "buy" mean in GWH activity?

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