Frequently asked questions about DLB activity

  • What does "buy" mean in DLB activity?

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