**Weekly Summary**

*The S&P 500 and Nasdaq ended the week sharply lower as concerns about AI infrastructure spending rattled technology shares. AMD's strong earnings highlighted an important distinction between current demand and the future returns investors expect.*

It was a difficult week to own AI stocks. The S&P 500 fell 2.7%, its worst week since April 2025, and the Nasdaq lost 3.4%. An early rally after the midterm elections gave way to heavy selling in technology shares. Friday’s rebound offered some relief, but it did little to repair the damage. Our AI holdings were hit as well, with several disappointing developments adding to the pressure. The week made clear how quickly confidence can unravel when investors begin to question the pace of growth already built into share prices.

### How the 2026 Midterm Elections Affected AI Stocks

Democrats won control of both chambers of Congress, and markets initially welcomed greater clarity in Washington. The S&P 500 rose 1.6% on Wednesday. By Thursday, attention had shifted to what the political change might mean for the AI buildout, particularly the risk of slower approvals for new data centers. The result itself does not tell us which projects will be delayed or which policies will pass. Still, companies priced for years of rapid expansion are vulnerable when the timetable becomes less certain.

Those worries fed an unusually severe selloff. The S&P 500 technology sector dropped 7.3% on Thursday, while the Philadelphia Semiconductor Index lost more than 12%. Investors were worried that slower construction could push back equipment orders and the revenues expected to justify enormous capital spending. Even a delay can matter when valuations depend on earnings several years away. For now, these are fears about the speed and economics of the AI expansion, rather than evidence that demand has suddenly disappeared.

 

### AMD Earnings: Strong Growth Meets Higher Investor Expectations

AMD’s results earlier in the week help put that distinction in perspective. Third-quarter revenue increased 45% from a year earlier, with data-center revenue up 97%. Those are strong numbers. Yet strong current demand does not settle the question of how long that growth can continue, or how much investors should pay for it. The market is becoming less willing to assume that every increase in AI spending will translate into attractive profits throughout the supply chain.

 

### Quantel's Take: What the AI Selloff Means for Portfolio Risk

For our portfolio, the setbacks deserve more attention than a general explanation that technology stocks had a bad week. Different AI businesses can still depend on the same spending cycle, leaving them exposed to the same change in expectations. A lower share price also does not, on its own, make a position more attractive. The useful question is whether the expected earnings have moved further out, whether the business faces a more lasting problem, and whether the valuation allows enough room for either possibility.

We remain constructive on AI’s long-term potential, but this week gave us reasons to be more cautious about the path from investment to returns. Election headlines will continue to move prices, and next week’s inflation data will matter for financing costs. For the AI names, the more durable test will be whether orders turn into revenue and cash flow on a reasonable schedule. A recovery would be easier to trust if it came with better evidence on those points.
