US markets witnessed a sharp correction in the semiconductor sector on Tuesday. The Philadelphia Semiconductor Index faced heavy selling immediately after hitting a fresh record high. The index dipped nearly 7 percent during trading, touching a low of 11,263.58, and ultimately closed more than 3 percent lower. The direct catalyst for this pullback was April inflation data released by the Bureau of Labor Statistics. The Consumer Price Index rose 3.8 percent year-over-year, exceeding market expectations, and increased 0.6 percent month-over-month. This data reinforced expectations that the Federal Reserve will maintain high interest rates or even hike them further. Financial market pricing indicates a significantly elevated probability of rate hikes within the next 12 months.

Consequently, semiconductor-related stocks came under widespread pressure, with almost the entire sector sliding. Mobile chip giant Qualcomm suffered the most severe losses, closing down more than 11 percent with an intraday drop nearing 15 percent, marking its worst single-day performance since March 2020. Intel and Micron Technology were no exception, falling nearly 7 percent and more than 3 percent, respectively. Although Intel has accumulated a staggering 227 percent gain year-to-date, it experienced significant volatility today. Additionally, shares of SanDisk, Advanced Micro Devices, Applied Materials, and ASML retreated to varying degrees. Lumentum and Credo in the optical communications sector both fell more than 5 percent. Notably, Nvidia emerged as one of the few chip giants to post gains against the trend, rising slightly by 0.61 percent, with its total market capitalization remaining near the high of 5.36 trillion dollars.

Market analysts suggest that this decline is primarily driven by technical profit-taking. The Philadelphia Semiconductor Index has surged more than 60 percent year-to-date, with some individual stocks like Intel and Micron posting even more remarkable gains. Parabolic rallies have accumulated substantial profit positions. A derivatives strategy chief noted that historic surges cannot sustain indefinitely, and a pullback following overheated momentum is inevitable. Some analysts warn that with sector valuations at elevated levels, a tightening macro environment could amplify volatility risks. Despite facing short-term selling pressure, the fundamental logic behind AI computing power demand remains fundamentally unchanged. Goldman Sachs recently significantly upgraded its forecast for DRAM and NAND price increases, and memory chip giants' stocks continue to hit new highs. While some investors are betting on continued declines through shorting ETFs, another perspective suggests this serves to create room for market fluctuations ahead of upcoming key events.
