US semiconductor stocks, which had been suffering from a wave of sell-offs, staged a sharp turnaround by surging across the board.
The Philadelphia Semiconductor Index (SOX), composed of 30 major semiconductor stocks listed in the US, jumped 8.19 percent on the 30th local time, marking its largest daily gain in about one year and three months since April 9, 2025 (18.73 percent).
The VanEck Semiconductor ETF (SMH) also leaped 6.82 percent, recording its biggest single-day increase since April 9 of last year (17.16 percent).
The iShares Semiconductor ETF (SOXX) also rose 8.5 percent.
The rebound was triggered by strong earnings from Microsoft (MS) and Lam Research.
Microsoft shares skyrocketed 15.5 percent, recording their largest single-day surge since 2008, after announcing solid growth for its Azure cloud and an expansion in capital expenditures.
The increase in market capitalization in a single day was approximately 450 billion dollars (about 659.7 trillion won), the largest scale in history for an individual stock.
Semiconductor equipment maker Lam Research saw its stock skyrocket 18.0 percent, marking its largest gain since 1999, after releasing strong earnings and guidance driven by AI-powered demand.
Memory-related stocks also surged.
Micron and SanDisk jumped 18.4 percent and 26.0 percent, respectively, as Samsung Electronics' warning that a memory shortage could persist until 2028 paradoxically acted as a positive factor.
The turnaround is particularly notable because both companies had recently experienced a synchronized decline when SK Hynix plummeted after failing to meet market expectations despite posting record earnings.
This rebound draws attention as it comes after a sell-off phase earlier this week where over 1 trillion dollars in semiconductor market capitalization evaporated due to skepticism over the profitability of AI investments.
