#美股行情 U.S. stocks premarket update: losses widen further, memory chips face intensifying pressure

Premarket trading continues to weaken, with pullbacks in popular technology stocks expanding further
Nvidia ‑1.26% premarket
SanDisk ‑3.11%,
SK hynix ‑2.09%,
Micron Technology ‑2.20%, making the memory chip sector the hardest-hit area premarket
Tesla ‑1.37%,
optical module maker Lumentum ‑1.70%
Chinese stock Alibaba ‑1.59%
Compared with the previous round of premarket data, AI chips, memory, and optical communications are all seeing increasingly severe pullbacks.
After the sharp overnight rally, signs of concentrated profit-taking are becoming increasingly evident.

Key market signals
1. The memory sector leads the declines
Micron, SK hynix, and SanDisk all fell sharply.
2. Nvidia's decline has widened, no longer maintaining a narrow range
After surging 8.25% the previous night, Nvidia accumulated substantial short-term profit-taking pressure and continued to retreat premarket. With no sudden negative catalyst, this is normal profit-taking after a sharp rally. However, this means Nvidia will have difficulty continuing to provide upward momentum for A-share computing power stocks tonight, and may instead weigh on sentiment. PCB, optical modules, and server hardware could easily be dragged down by overseas markets at tomorrow's open.
3. Optical communications stocks also weakened in tandem
Lumentum fell 1.70% premarket
4. Chinese stocks also weakened in tandem
Alibaba's premarket decline widened

Premarket moves are only a preview; U.S. stocks can be highly volatile during regular trading, and the actual closing prices tonight will be decisive. This does not constitute any investment advice. $NVDA $SNDK ‌ ‌
