The Election Week Sorted the AI Trade

NEW YORK, Nov. 6 — TheThe week of the midterm elections ended with a rally in chip shares that undid little of the week. The PHLX Semiconductor index rose 4.21 percent on Friday and still finished 12.15 percent below its close of Oct. 30.The Wider MarketOver the same week the Nasdaq Composite fell 3.37 percent, the S&P 500 2.68 percent and the Dow Jones industrial average 0.94 percent. Bond yields fell too: the 10-year Treasury yield ended the week at 4.86 percent, from 4.94 percent, by the Treasury’s count.

Taken whole, and by this paper’s reading, the five sessions sorted the trade in artificial intelligence roughly by each company’s place in the build. Suppliers of AI data centers took the five worst losses, and three of the biggest buyers, Amazon, Alphabet and Microsoft, ended the week higher.

The heaviest losses were the suppliers’. Lumentum, which makes optical parts, lost 35.94 percent from the close of Oct. 30 to Friday’s close; Marvell, 28.11 percent; Astera Labs, which sells connectivity for AI racks, 26.28 percent; and Micron, the memory maker, 22.01 percent. Vertiv, which makes power and cooling equipment for data centers, lost 21.35 percent. Lam Research, Applied Materials and KLA, which make chipmaking equipment, lost between 12.30 and 16.17 percent. The divide was uneven: Nvidia, Broadcom and TSMC fell less than CoreWeave and Nebius, and Arista, which makes networking systems for data centers, gained 1.15 percent over the week.

Two of the neoclouds fell about as far as the equipment makers.NeocloudsNewer AI cloud companies, such as CoreWeave and Nebius, that lean on borrowed money. The hyperscalers have broader cloud businesses and more internally generated cash flow, JPMorgan Asset Management wrote in an Oct. 20 note, as CNBC reported. Nebius fell 15.99 percent over the week and CoreWeave 15.44 percent; IREN, even after rising 20.02 percent on Friday, lost 9.65 percent. Oracle, which CNBC describes as pouring money into building out AI infrastructure, fell with them, by 11.15 percent.

At the other end, Amazon rose 7.88 percent over the week, Alphabet 1.77 percent and Microsoft 1.67 percent, the only three of the 23 companies in the chart to finish higher.AMZNNasdaq266.93▲7.63+2.9%Amazon · Monday’s session Apple and Meta lost less than 1 percent each.

Microsoft reported $45.2 billion of capital expenditures and finance leases, CNBC reported.

The power producers sat in between. Vistra led Wednesday’s fall among the 23, losing 13.83 percent that day. Over the week Talen Energy lost 1.31 percent and Constellation Energy 4.74 percent, while Vistra, up 10.55 percent on Friday, finished 9.81 percent lower, about where Nvidia did, at 8.80 percent.

The Reasons Given

The prices do not explain themselves; others have offered reasons. On Wednesday, the day after the vote, the trade split in two. James Sullivan, a managing director and co-head of global fundamental research at JPMorgan, told CNBC’s “Squawk Box Asia” on Thursday that differences in borrowing costs played a key role: spreads had widened significantly for the neoclouds, leaving their cost of additional capital substantially higher than the hyperscalers’. “The fact that you’re seeing this bifurcation in equity performance is largely driven by the view that existing capacity is significantly more valuable now because of incremental supply constraints,” he said.

On Thursday the whole trade fell, on what CNBC called investors’ fears about a slowdown in the build-out of artificial intelligence. On Friday afternoon CNBC reported, citing people familiar with the matter, that Microsoft is shrinking its roster of neocloud partners as it focuses on a few key suppliers and builds out its own data centers, though it is still in the evaluation stage and has not decided which neoclouds it will stop using; two of the people said it had opted not to renew a deal with Oracle. Bloomberg had reported the plans earlier, CNBC noted. A Microsoft spokesperson said its infrastructure strategy is “built on flexibility and choice,” and added: “We regularly review these investments against customer demand.”

Bank of America put Thursday’s rout down to price rather than profit. “The recent sell-off in AI-exposed IT hardware has come from lower valuation multiples, not lower earnings estimates,” Wamsi Mohan, an analyst at the bank, wrote to clients on Friday, as CNBC reported. “Our FY28 EPS estimates remain at or above consensus for most of the group.”

One Week

This paper’s reading is that the market marked down hardest many of the companies that sell into the build or borrow to add to it, while three of the biggest buyers gained; Mr. Sullivan put the split down to the value of capacity already in hand. It fits the week’s prices; it does not prove a cause, and it covers five sessions. Friday’s bounce was broad: of the 23, all but Microsoft, Amazon and Apple rose, and AMD gained 11.04 percent.

One neocloud sees a gap between its shares and its customers. Daniel Roberts, IREN’s co-chief executive, told CNBC of a “disconnect between what we’re seeing in public market and what we’re seeing at the customer level.” On IREN’s earnings call he acknowledged the challenge that market conditions present, as CNBC put it: “Capital markets have become more selective in the last few weeks, and the questions have undoubtedly moved from how big the contract is to whether it can be delivered, financed, and run at a profit.”

The first tests come soon: CoreWeave reports its third quarter on Tuesday, Nov. 10, Nebius also reports next week, CNBC reported, and Nvidia reports on Nov. 17.
