US chipmakers climb as tariff impact seen as contained

U.S. chipmakers' shares rise in premarket trading as several companies avoid Trump's latest tariffs

Nvidia NVDA.O up about 1%, Advanced Micro Devices AMD.O and Intel INTC.O climb nearly 2%

Micron Technology MU.O jumps 4%, Super Micro Computer SMCI.O gains about 1.5%

Broadcom AVGO.O, Marvel Technology MRVL.O and Qualcomm QCOM.O adds between 0.5%-0.8%

Philadelphia Semiconductor Index .SOX is up around 11.5% YTD

"Given the complexity of the semiconductor supply chain, details on how, and on whom the tariffs will be applied are critical to fully assess their impact," UBS GWM says

Adds, tariff impact appears "manageable" as most chips enter U.S. within systems, not as standalone components
