Semiconductor Selling Signals Rotation Out of AI

The VanEck Semiconductor ETF, SOXX, fell to 509.94 on Monday from 527.01 on Friday and 551.24 two sessions earlier, deepening a pullback that has left the fund more than 10% below its 50-day moving average of 568.74. That is notable because the group had only recently powered to a record run, with SOXX surging above 655 in late June before losing altitude. The selloff has also pushed the ETF’s 14-day RSI down to 39.4, a conventional technical reading that indicates fading momentum rather than outright panic, while the MACD remains below its signal line, a sign the downtrend is still intact.

Nvidia and AMD, the two names most associated with the AI buildout, also weakened sharply. Nvidia closed at 197.48, down from 206.84 the prior session, while AMD dropped to 485.56 from 521.95. Both remain well above their longer-term averages, but the recent declines suggest investors are becoming more selective about paying up for every AI-linked dollar of revenue. Nvidia’s RSI at 50.4 points to a neutral stance after a volatile run, while AMD’s 44.0 shows the stock has lost some of its earlier momentum. For investors, that combination raises the risk that the trade is shifting from a broad rerating to a stock-picker’s market.

The economic backdrop helps explain why the sector remains so important. Semiconductor demand is still being driven by data-center spending, AI training and a push by governments to secure domestic supply chains. Reuters reported that Chinese chip maker CXMT saw its market value jump sixfold on debut, while China’s chip exports have nearly doubled and South Korea’s economy has benefited from the same cycle. That underscores a key point: chips are no longer just a technology story but a macro one, tied to trade balances, industrial production and national competitiveness.

There are, however, clear bear-case arguments emerging. The first is valuation fatigue after a historic run. The second is that supply is improving just as expectations for AI-related demand have become extremely high, creating a setup where even strong earnings may not be enough to sustain multiples. The third is that the market is becoming more sensitive to policy and geopolitics, from export controls to supply-chain localization, which can tighten or distort pricing. AMD’s own filings note the semiconductor industry’s cyclical supply-demand imbalances, excess inventory risks and pricing pressure, reminders that the sector’s long-term story does not eliminate the cycle.

The bull case is that the selloff is still a correction inside a secular growth trend. Earnings from Nvidia, AMD and other AI-linked suppliers continue to be driven by hyperscaler spending, and the broader ecosystem — from foundries to equipment makers — remains supported by heavy capital investment. If incoming results confirm that demand is still outstripping supply, the recent weakness could prove to be a reset rather than a reversal.

For now, the message from Monday’s trade is that investors are no longer willing to chase semiconductors blindly. The group remains central to the market’s earnings story, but after months of outsized gains, it is being asked to justify its premium with numbers rather than narrative. The next catalyst will be whether upcoming earnings and guidance can validate continued AI spending, or whether the market keeps de-rating the trade as too much optimism was pulled forward.
