Pre-Market Briefing on Oct 16: CoreWeave Swung From −9.5% to +5.94% as Yields Fell; US September Import Prices Tonight

 

All three indexes rose, in three distinct sizes: the Dow +1.08%, the S&P 500 +0.33% and the Nasdaq only +0.08%. The difference is in what they hold: the Dow does not carry the heaviest-weighted technology names and the Nasdaq does. The Philadelphia semiconductor index fell 0.88%, a seventh straight session lower, as money left the AI trade for healthcare, materials and financials.

 

When indexes rise together but the sizes differ by an order of magnitude, the question is not how far they rose but which constituents failed to keep up. Moving as one says risk appetite is shifting; moving the same way with a tenfold gap says capital is re-sorting between categories, and the category at the back of that queue was the compute chain.

 

TSMC is the clearest illustration. Third-quarter revenue was $46.72B, up 50.9% from a year earlier, net profit rose 68.7% and fourth-quarter guidance came in at $52.3B to $54.3B, all records; but gross margin eased from 67.7% in the second quarter to 66.4%, and the stock fell 1.80% to $422.25. Nvidia fell 1.84% to $217.23 on 126 million shares, in line with its recent average.

 

When record results are met with a falling share price, first establish which question the market has switched to. Volume did not expand, so this was valuation being repriced rather than a rush for the exit, and with revenue and profit accelerating the only line marked down was the margin. Collapse that into one phrase about technology weakness and you wait on demand when you should watch cost.

 

 

Unit: %. The basis for these six is compute-rental names grouped by hand on what they do, which is neither the sector field nor an automatic peer list. Core Scientific sits at one end on +6.99% and IREN at the other on −0.56%, 7.55 points apart, with the six averaging +2.50%.

 

CoreWeave gained 5.94% for second place, 3.44 points above the average of the six, and five of the six rose while one fell. This was neither a move at the head of the group nor a move against it: the sector average is positive, at a 1.11% gain for software infrastructure, so nothing ran against it, and CoreWeave placed second rather than first, so nothing led it either.

 

Leading a group and moving against it are both terms with tests behind them, and when the tests fail the honest thing is to state the numbers. Neither test held here, so what can be said is the rank, the margin and the count.

 

Two different denominators sit close together here. The 3.44 points is measured against the six names grouped by hand, which averaged +2.50%; the relative strength of 74.2 in the five-dimension score is measured against the software infrastructure sector, which averaged +1.11%. Both stand on their own, but neither confirms the other.

 

What moved the stock was not the company but the rate. It borrows to buy GPUs and rents them out, so its share price follows its own bonds rather than only its revenue. The 10-year Treasury yield fell 9 basis points that day, the expected cost of money fell with it, and a stock that had been down 9.5% intraday finished the day higher. Hold the other side at the same time: an industry report published the day before put four in five compute landlords out of independent existence by the end of this decade, and the company held $5.52B of cash at the end of June, with financing terms left to later quarterly filings. Micron (MU) is the supporting name, up 1.87% after also falling more than 4% intraday, on the same reading.

 

Unit: 0 to 100, against peers and its own one-year history, measured over a one-year window rather than the single session. Peer rank is highest at 80.0, relative strength reads 74.2, valuation heat 34.4 and trend position 11.2, while the weakest, volatility, reads 0.0 and sits on the centre point.

 

One corner comes close to the rim and another rests on the centre. Relative strength at 74.2 measures how much stronger it was than its sector that day, while volatility at 0.0 measures how much it has moved over the past year: different reference sets, different windows, so both hold at once. The price confirms it, with the stock still at only 11% of its 52-week range.

 

Strong today and steady over a year are two questions to ask separately. One compares across names, the other against its own past; read them together carelessly and "stronger than its sector today" becomes "less risky than its sector".

 

 

The September import and export price indexes land at 12:30 UTC, an hour before the 13:30 UTC open, with September industrial production and capacity utilisation at 13:15 UTC. Pre-open results are banks and insurers (TRV, CFG, MTB, RF and TFC), with no technology names today.

 

This is the last of three inflation readings this week: September CPI on Wednesday ran 3.7% higher than a year earlier, September PPI on Thursday rose 1.3% on the month, the largest step since March 2022, and tonight's import prices are the only direct reading of tariff cost at the border. 🔴 Basis warning: the PPI figure is a monthly change while the CPI figure is a 12-month change, so the two cannot be compared. Import prices measure the landed price of goods entering the US, at the front of the chain running from tariffs to company costs to margins and capital spending. What it says about technology sits in the capital goods component, where computers, peripherals and semiconductors are found: the upstream price of AI hardware.

 

Unit: %, 12-month changes in import prices for NAICS 334 (computers and electronic products), measured as the US landed price and excluding domestic mark-up, all drawn from zero on one shared scale. May reads 7.7, June 8.0, July 9.4 and August 10.3.

 

Skip the headline because fuel pulls it around: August fuel was up 26.8% from a year earlier, while 334 covers only computers, semiconductors and communications equipment. Four months carried it from 7.7% to 10.3%, and the monthly step steepened too, at +0.4% in June, +1.2% in July and +1.4% in August: acceleration rather than a peak.

 

When a component and the headline point the same way there is no need to separate them, and when they disagree the component is the one to read. Fuel's weight inside the headline pulls the conclusion off, and the only box that sets the import cost of AI hardware is 334.

 

Unit: %, the six components of August import prices grouped by end use, as 12-month changes, all drawn from zero on one shared scale. Industrial materials are highest at 17.5, capital goods including computers and chips read 7.3, non-fuel overall 5.5, food and beverages 3.0, consumer goods 2.4 and vehicles and parts 0.8.

 

Only industrial materials run higher than capital goods among the six, while consumer goods read 2.4% and vehicles 0.8%. This round of price increases is concentrated on the production side and has not reached the shelf price yet.

 

Within one report, high production-side components against low consumer-side components read as "cost has not been passed on", not as "inflation is mild". It eats company margin first, and only then does the decision about passing it on get made, so those two low consumer lines are an unsettled bill rather than good news.

 

Two steps tonight. First, whether 334 accelerates for a fifth month: it ran +10.3% in August, and another step up means the import cost of AI hardware is still rising. Second, whether the non-fuel line heads toward 6%: it ran 5.5% in August against a headline of 7.0%, with the whole difference in fuel, and the firmer it is, the harder it gets to soften the rate path at the October 27 and 28 meeting, which would price the discount rate on highly valued technology names again.

 

 

A: Neither. Leading requires being the highest in the set, and Core Scientific rose 6.99%; moving against requires a negative sector average, and software infrastructure averaged a 1.11% gain. What can be said is second place and 3.44 points above the average of the six.

 

A: Not revenue, but the cost of money. The 10-year Treasury yield fell 9 basis points, and this company borrows to buy GPUs and rents them out, so a lower yield lowers the payback bar on the same GPU purchase. Its 2032 bonds touched a 15% yield at one point during the session (an intraday reading at a single moment) while the 10-year Treasury stood at 5.10% the same day, and the gap between the two is the extra price the market asks of it.

 

A: No, the reference sets and the windows both differ. Relative strength measures how much stronger it was than its sector that day, against a sector average of +1.11%; volatility measures how much it has moved over the past year. Both hold at once.

 

A: NAICS 334, computers and electronic products, rather than the headline index that fuel pulls around. It ran 7.7% in May, 8.0% in June, 9.4% in July and 10.3% in August; whether a fifth month of acceleration follows is tonight's first question.

 

A: It depends which end of the chain you stand on. For the cloud operators buying the kit, an import price up 10.3% from a year earlier is a rising cost that squeezes capital spending; for the supply chain selling it, the same number is pricing power. The reading is not one-directional.
