Amkor stock (AMKR) slips before holiday reopen as insider sale notice surfaces
Amkor shares fell 2.5% to $48 Friday after an SEC filing showed officer Mark N. Rogers planned to sell 5,000 shares following an option exercise. The drop came despite a 1.2% gain in the Philadelphia Semiconductor Index. U.S. markets reopen Tuesday after the holiday, with Amkor’s next earnings report expected around Feb. 9.
