#AI芯片股重挫纳指周跌3.4%
The Philadelphia Semiconductor Index fell 12.15% for the week, Micron plunged 22% — this isn’t a pullback; it’s a “historic-scale reckoning” for the AI narrative
The Nasdaq fell 3.37% for the week, marking its fourth straight weekly decline. But the real damage was in semiconductors: the Philadelphia Semiconductor Index plunged 12.15% for the week, including a 12.25% rout on Thursday alone, its second-largest single-day drop on record.
A look at individual stocks makes for grim reading. Micron fell 22.01% for the week, SanDisk dropped 22.26% in a single day, Marvell fell 28.11%, Lumentum plunged 35.94%, AMD shed more than 11% during the week, and Nvidia fell 8.80% for the week. Memory chips, compute chips, optical communications — not a single link in the AI hardware chain was spared.
Why is this time different? In the past, when chip stocks pulled back, the market saw it as a “chance to get in,” because the AI capital expenditure narrative had no cracks. But this week, two cracks appeared. The first is political: after Democrats swept the midterm elections, Texas’s governor-elect made clear that “the current data center projects must be stopped,” while an elected official in South Carolina bluntly said that “communities, not data center companies, should decide.” Bernstein estimates that about 244 gigawatts of capacity — 55% of projects under construction — face political risk. The second crack is in credit: CoreWeave’s five-year CDS spread topped 1,000 basis points, a record high — the credit market is already pricing in the possibility that “the financing chain for AI infrastructure could break.”
Trading note: The Philadelphia Semiconductor Index’s weekly drop is already approaching the scale of a “capitulation sell-off,” but “a big drop” doesn’t mean “the bottom is in.” The real signs of a floor won’t be found in the candlestick charts, but in clarity around data center approvals and in CoreWeave’s earnings and financing progress. Until these two factors play out, any rebound in chip stocks is more likely to be short covering than a trend reversal.
