On July 7, Advanced Micro Devices declined 3.01% overnight, trading at 536.26 USD/share, with turnover of $48.69 million. The stock had previously surged 6.61% during regular trading to close at $552.05 before giving back gains in after-hours activity.

On the news front, AMD's options market saw a single institutional-scale bearish call spread valued at approximately $712 million, with total single-day large-order bearish volume reaching $715 million. This represents a significant divergence between options market sentiment and the stock's daytime rally. Additionally, a $3.39 million put purchase at the $555 strike signals short-term defensive positioning.

The broader semiconductor sector experienced collective weakness overnight, amplifying pressure on AMD. Among sector peers, Micron Technology fell 6.27%, Marvell Technology dropped 4.88%, Intel declined 3.40%, Broadcom lost 1.81%, and NVIDIA slipped 1.10%. The sector-wide retreat compounded the bearish options signal to weigh on AMD's overnight performance.
