Frequently asked questions about THRM activity

  • Which institutional owners are buying THRM?

    Institutional owners buying THRM include investors who have either initiated new positions or increased their existing holdings based on recent SEC 13F filings. 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 THRM activity?

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

  • Is institutional interest in THRM increasing?
