  • What does "buy" mean in PODD activity?

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