  • What does "buy" mean in GSM activity?

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

  • Is institutional interest in GSM increasing?
