On July 7, STMicroelectronics fell 4.94% in regular trading, trading at 67.96 USD/share, with turnover of $121 million. The decline was driven by a global semiconductor selloff triggered by Samsung Electronics' stock plunge following its Q2 earnings release.

Samsung Electronics reported Q2 operating profit of 89.4 trillion KRW, up approximately 1,810% year-over-year and exceeding analyst expectations of 84.2 trillion KRW. Despite the record-breaking results, Samsung's stock fell nearly 7% in Seoul in a classic sell-the-fact reaction, as its shares had already surged over 158% in the prior 18 months. Investors expressed concerns that the memory chip pricing cycle may be peaking and that AI capital expenditure growth could decelerate.

The negative sentiment rapidly cascaded across global chip stocks. European semiconductor names including ASML, Infineon, and STMicroelectronics declined 3% to 7%. In the U.S., Micron Technology fell 6.47%, Intel dropped 7.38%, AMD declined 6.93%, and Marvell Technology lost 6.38%.
