Frequently asked questions about WM activity

  • What does "buy" mean in WM activity?

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

  • Is institutional interest in WM increasing?
