  • What does "buy" mean in TMDX activity?

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

  • Is institutional interest in TMDX increasing?
