Nasdaq Soars 2.08% Driven by Spectacular Semiconductor Rally

Semiconductors Take Control of the Session

The day was dominated from start to finish by chip manufacturers and equipment makers for the semiconductor industry. Advanced Micro Devices recorded the largest increase on the Nasdaq with a remarkable jump of 18.61%, closing at $421.39. Chip designer Arm Holdings followed with a gain of 13.63% to $237.30, reaffirming investors' renewed interest in this segment. Equipment manufacturers also saw gains: Lam Research rose 7.75% to $297.17, while ASML Holding climbed 7.06% to reach $1,544.74. Nvidia, a heavyweight in the sector, joined the movement with a 5.77% increase to $207.83. Intel also benefited from this trend, advancing 4.49% to $113.01. Applied Materials (+4.33% to $428.62), KLA Corporation (+4.81% to $1,816.29), and Microchip Technology (+4.51% to $102.92) rounded out this very homogeneous picture. The only discordant note in the tech universe was PDD Holdings, which rose 5.75% to $102.31, without any direct link to semiconductors.

CDW Plummets, Utilities and Services Under Pressure

Against the backdrop of technological euphoria, CDW Corporation experienced a real stock market crash with a drop of 20.36%, with the share price settling at $108.95, marking by far the largest decline of the index. Energy and service sectors also suffered: Diamondback Energy fell 5.38% to $195.08, while Verisk dropped 5.30% to $170.89. The software and professional services sector was not spared. Workday gave up 4.85% to $122.63, Thomson Reuters lost 3.96% at $91.68, and Atlassian slipped 3.84% ending at $88.80. Utilities, traditionally defensive, took a hit: American Electric Power declined 3.27% to $132.56 and Exelon by 2.51% to $45.02. Cisco slid 2.82% to $91.64, while Autodesk closed down 2.55% at $243.08.

A Noticeable Session of Sector Rotation

This day of May 6 illustrates a clear sector rotation, with investors seemingly temporarily moving away from defensive stocks and services in favor of a massive bet on semiconductors. The Nasdaq's 2.08% gain, which brings it back to life after several dull sessions, relies almost exclusively on this concentrated dynamic. The magnitude of the movements, particularly evident in AMD and CDW at opposite ends of the spectrum, indicates high sector volatility in a market otherwise lacking a major macroeconomic catalyst. At 28,599.17 points, the technology index ends this mid-week on a decidedly bullish note, driven by persistent hopes around artificial intelligence and chip demand.
