FormFactor is trading 4.23% up at $106.00 in pre-market after an overnight semiconductor-equipment rebound, with the catalyst unclear.

  • It reverses part of the August 28 selloff; no company-specific announcement, earnings release, analyst action, or other direct catalyst was identified for the August 31 pre-market move.
  • The latest major result remains the July 29 earnings beat and strong Q3 guidance; the press-release page shows no newer major announcement through August 25.
  • U.S. futures are modestly lower; confidence in the catalyst is low.
