  • What does "buy" mean in UNP activity?

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

  • Is institutional interest in UNP increasing?

A higher number of additions typically signals increasing participation among large filers, but it should be read alongside position sizes and the full table.
