Aehr Test Systems is trading 4.94% up at $111.44, extending momentum after its August 4 follow-on production order.

  • The order came from its lead silicon photonics customer for an automated FOX-XP multi-wafer burn-in system supporting optical transceivers and chip-to-chip optical I/O.
  • No separate August 11 announcement was found; the move appears company-specific rather than broad market strength.
  • The S&P 500 is up 0.10%, while the Nasdaq Composite is down 0.03%, providing limited support.
