ChipMOS Technologies is trading 7.08% higher at $72.56, rebounding from its September 29 close of $67.76 after a 5.34% decline. - On September 29, the company reported August EPS of NT$0.62, more than double year over year, while net profit rose 117.6%. - Coverage tied that report to a premarket decline, not the September 30 rebound; no verified company-specific catalyst has been identified. - Broader markets are positive, but that backdrop does not establish the reason for the move.
