Nanya Technology is trading 7.82% down now at $477.50, after falling from the September 2 close of TWD 518.00; no reliable company-specific catalyst directly explains the decline.

  • Nanya Technology reported August revenue of NT$44,690 million on September 2.
  • Recent coverage noted CMC Magnetics’ NT$553 million purchase of Nanya shares, making both developments unlikely explanations.
  • The broader U.S. market was positive, so broad market sentiment does not appear responsible.
