Memory chip companies suffered some of the largest losses in U.S. trading on Tuesday: Sandisk shed 14%, Western Digital sank nearly 7%, and Seagate lost more than 8%. SK Hynix's U.S. shares dropped 9%. Intel declined by almost 6%, while AMD gave up 8%.
On mainland Chinese markets, the ChiNext 300 index rose 1.43% on Wednesday, while Hong Kong's semiconductor-focused stock gauge fell 2.5%.
The Philadelphia semiconductor index had climbed 92% in the previous year, even as it dropped nearly 20% over the last month.
Morningstar's chief equity strategist, Michael Field, stated, "This decline appears to be driven largely by sentiment rather than fundamentals." He added, "Simply put, it's loss of confidence."
Charlie Dai, a Forrester vice president and principal analyst, stated that investors are questioning if immediate revenue streams can support the massive AI expenditure, and some are concerned about increasing rivalry in the chip and AI infrastructure space. Dai added that the sell-off is "less about weakening AI demand and more about a repricing of expectations after an exceptionally strong rally."
David Riedel, who runs Riedel Research Group, informed CNBC's "Squawk Box Asia" that the decline shows investors "giving back a little bit of the froth that was in the AI market." He said memory chipmakers "will be fine" but "just have to give back some of those sudden gains," and added that "the market is healthy."
Kieron Poon, who manages Asian equities for Aberdeen Investments, noted that the recent market turbulence "has not changed our long-term positive view" and that "the recent market pullback has brought valuations to more attractive levels, creating opportunities for us to add exposure to high quality businesses at more reasonable prices."
Alphabet announced that it will raise its capital expenditure projections for 2026 due to the urgent need to construct additional AI infrastructure.
