ASML closed 2.43% higher at €1,280.40 on Euronext Amsterdam on 6 November, a day after it closed 6.55% lower, on Yahoo Finance exchange data. By our arithmetic it ended the session having recovered 34.7% of its 5 November fall, down from 37.7% at our 09:09 UTC morning read.
The STOXX Europe 600 closed 1.04% lower at 648.08 and the DAX 2.02% lower. Across the five European chip stocks we tracked, the average share of the 5 November fall recovered at the close was 20.4%, by our arithmetic, against 53.5% for the 12 US AI stocks we track at 9:45–9:46 a.m. ET, an intraday read.
Business Pill · Financial Conditions
A short explainer on financial conditions: how the price of credit moves with markets. It teaches the general idea only and does not discuss European chip stocks.
The key insight: By our arithmetic on Yahoo Finance exchange data, four of the five European chip stocks we tracked closed higher on 6 November and recovered an average 20.4% of their 5 November fall, while the DAX closed 2.02% lower; ASML closed 2.43% higher, having recovered 34.7% of its fall.
Daily changes at the 6 November close against the 5 November close, by our arithmetic on Yahoo Finance exchange data: ASML +2.43%, ASM International +2.17%, BE Semiconductor +2.20%, Infineon -0.08%, STMicroelectronics +1.17%. SAP closed 2.50% lower and the Euro STOXX 50 1.04% lower.
Shares of the 5 November fall recovered by the close, by our arithmetic: ASML 34.7%, ASM International 28.9%, BE Semiconductor 27.9%, STMicroelectronics 11.4%. Infineon closed below its 5 November close.
The morning moves did not all hold. As we reported in Europe’s Chip Stocks Rise After Nvidia Rout; ASML Up 2.6%, at 09:09 UTC ASML was up 2.64%, Infineon 2.32%, ASM International 1.73%, BE Semiconductor 1.70% and STMicroelectronics 1.34%. By the close, by our arithmetic, ASML, Infineon and STMicroelectronics had smaller gains or a loss against the 5 November close, while ASM International and BE Semiconductor ended higher than at the morning read.
Change against the 5 November close at 09:09 UTC on 6 November (intraday) and at the 6 November close, for five European chip stocks, the STOXX Europe 600 and the DAX. Yahoo Finance exchange data; our arithmetic.
The Week
From the 30 October close to the 6 November close, by our arithmetic: ASML -9.37%, ASM International -10.99%, BE Semiconductor -6.49%, Infineon -9.19%, STMicroelectronics -10.46%. Over the same week the STOXX Europe 600 changed +0.21%, the Euro STOXX 50 +0.58% and the DAX -0.09%.
Over the two sessions from the 4 November close, ASML was -4.28% and STMicroelectronics -8.28%, by our arithmetic.
The Credit Side
On the lending side, the European Central Bank is considering a review of bank lending connected to data centers, according to Bloomberg News, citing people familiar with the matter, as reported by Investing.com; the ECB declined to comment. We covered it in an update to BoE Probes Tenantless Data Centre Loans; $1.75T Debt Seen. Bloomberg also ran a story headlined “AI Deal Windfalls Help Shield European Credit From Selloff”, which we read by headline only.
As we reported in AI Stocks Win Back $774B of $1.45T at the Open; AMD Up 12.6%, the 12 US AI stocks we track were about $774.0 billion above Thursday’s close at 9:45–9:46 a.m. ET, about 53.5% of Thursday’s $1,447.4 billion loss, by our arithmetic on Nasdaq intraday prices. Those are intraday figures; Europe’s are closes. The US session was still open when Europe closed.
The Business Lever
The business lever is equipment: ASML, ASM International and BE Semiconductor sell the machines and packaging tools that chipmakers buy, so their shares trade on expected chip capacity spending.
As we read the closes, the split between Europe’s chip stocks and its indexes was there at the close: four of five chip stocks closed up while the STOXX Europe 600, the Euro STOXX 50 and the DAX closed lower.
As we read the morning and the close together, the moves within the group diverged: ASM International and BE Semiconductor ended above their 09:09 UTC readings, while Infineon gave back its morning gain, by our arithmetic.
As we read the comparison, Europe’s average recovery of 20.4% sits below the 53.5% we counted for 12 US AI stocks early in the US session, but one is a close and the other an intraday read.

Three Implications
FOR ASML It closed 2.43% higher at EUR 1,280.40 and was still 9.37% below its 30 October close, by our arithmetic.
FOR THE WEEK All five chip stocks closed the week 6.49% to 10.99% below their 30 October closes, while the STOXX Europe 600 was 0.21% higher, by our arithmetic.
FOR LENDERS The ECB is considering a review of bank lending connected to data centers, according to Bloomberg News as reported by Investing.com; the ECB declined to comment.
The analysis says: “It is a sovereign-scale financing problem dressed in tech-company clothing — and the financial architecture is starting to invert.”
As we read it, Europe’s equipment makers sit upstream of that financing, and on 6 November supervisors were weighing the lending side while the equipment shares closed higher. The analysis predates this session and does not discuss European share prices.
What Is Not Established
The closing prices are Yahoo Finance exchange data, which can be delayed; we did not read the exchanges’ own official close files. We did not compute market values. We read Bloomberg’s credit story by headline only and the ECB report through Investing.com’s write-up. We do not know why some chip stocks gave back part of their morning gains while others added to them, and we found no company statement on the moves.
This Week In The AI Supercycle
Anthropic’s Reality Check, The Capital Squeeze, & The New World Order
This week’s issue: for two years the AI build-out was priced as a growthstory. This week it started being priced as a credit story.
Europe’s chip stocks ended 6 November having recovered an average 20.4% of their 5 November fall, by our arithmetic; ASML closed 2.43% higher, while the STOXX Europe 600 closed 1.04% lower and the DAX 2.02% lower.
A note on sourcing. Closes for 30 October and 4, 5 and 6 November are Yahoo Finance exchange data (Euronext Amsterdam, Euronext Paris and Xetra), which can be delayed; we did not read the exchanges’ own official close files. Percentage changes and the shares of the 5 November fall recovered are our arithmetic. The morning, US and Taiwan figures are from our earlier pieces.
