# Nvidia, Micron and AMD Leads Chip Rally Samsung Strike Threat Shakes Chip Supply

Samsung Electronics (SSNLF) labor talks collapsed on Wednesday, increasing the possibility of a strike that could tighten global memory-chip supply and lift semiconductor shares.

Micron Technology climbed about 4%, while Seagate Technology (STX) gained about 2%, Western Digital (WDC) rose nearly 2% and Sandisk (SNDK) added more than 2%. Nvidia advanced about 2%, and AMD rose roughly 2% as investors reacted to potential supply-chain pressure.

Broadcom (AVGO) gained about 2%, Qualcomm climbed more than 3% and chip-equipment makers ASML (ASML), Lam Research , Applied Materials (AMAT) and KLA also traded higher. The gains followed Samsung management's rejection of a proposal previously accepted by union representatives.

A broader work stoppage is expected to begin Thursday unless both sides return to negotiations. Samsung shares slid as much as 4% after the talks failed, reflecting concern that prolonged disruptions could affect supply for products ranging from AI servers to smartphones and electric vehicles.
