Frequently asked questions about BL activity

  • What does "buy" mean in BL activity?

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

  • Is institutional interest in BL increasing?
