The activity table above highlights which funds added shares in the latest reporting periods and how their positions changed over time.

  • What does "buy" mean in SENS activity?

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

  • Is institutional interest in SENS increasing?
