The S&P 500 fell 0.51% on Monday 2 November, a smaller move than Friday's 1.82% drop. The selling reached further down the AI hardware and software chains, though. Single-stock moves ran well beyond the index. Weekly figures below run from the 26 October close.
Marvell Buys Lumentum
Bloomberg's talks report from Thursday became a signed deal before the open. Each Lumentum share converts into 4.5 Marvell shares, which leaves current Marvell holders with about 67% of the combined company. MRVL (-12.72%) closed at $171.41 on 2.87 times average volume. The deal explains only Monday: Marvell had already lost 13.24% on 29 October and 10.05% on 30 October. Sources disagree on the deal size, with most headlines at $115bn and one WSJ figure at $80bn.
LITE (-18.59%) closed at $684.40. The fixed exchange ratio ties its value to Marvell's price, and the quarterly results published the same day beat expectations without helping. Stifel downgraded to Hold while Raymond James upgraded to Strong Buy and called the reaction overdone. CIEN (-11.34%) closed at $284.34 on sympathy selling, with no news at Ciena. Its backlog of $8.5bn is unchanged, and the shares sit 31.05% below their 7 August close.
Intel's Fallout and the Memory Slide
Friday's collapse in Intel carried on. INTC (-8.80%) closed at $59.97 on 2.13 times average volume, 33.71% below its 26 October level. No company announcement came out, and the extension looks like continued repricing of the PC warning. AMD (-7.52%) closed at $466.84 and has lost 26.10% over 20 sessions. Its results on 3 November give the first independent read on whether Intel's forecast of a 12% PC market shrinkage in 2026 reaches AMD's client business.
The memory and server group fell together. WDC (-7.52%) closed at $338.59 after Kioxia guided its December quarter below estimates. Western Digital's own results were strong and the shares are still up 80.58% this year. STX (-7.88%) closed at $593.76 after a run of target cuts and a Summit Insights downgrade to Hold, which is the likely driver but remains unconfirmed. SMCI (-7.62%) closed at $30.44 ahead of its results on 3 November, with Dell and HPE down about 7% as well. P (-10.40%) closed at $113.78, and the only explanation on offer is broad tech weakness.
Software Sell-Off, Third Week
The de-rating that began with ServiceNow and F5 results kept going, mostly on names with no news. DDOG (-8.15%) closed at $216.10 on a third straight decline, and Okta (OKTA, -11.22%) closed at $184.87. Okta's fall followed a Department of Homeland Security data-leak story on Friday, whose link to the price is unproven. FTNT (-7.25%, -31.16% wk) closed at $126.21, just under its 200-day average.
The earlier casualties settled. NOW (+0.85%, -32.98% wk) closed at $106.01, its first gain since the record one-day fall. FFIV (-4.08%, -29.69% wk) and RDDT (-0.83%, -34.29% wk) moved little. Reddit trades at 9.9 times forward earnings, which already allows for lasting damage from the fall in Google referrals.
Results Winners Hold, IDEXX Joins
The post-earnings rallies from last week held and in places extended. CVNA (+5.43%, +27.19% wk) closed at $72.00 and PNR (+6.49%, +27.78% wk) at $70.56, with no news behind either Monday gain. GEN (+2.61%, +22.45% wk) closed at $29.89, up while software peers fell, on a beat-and-raise.
IDXX (+21.85%) is the new entry, closing at $671.64 after third-quarter revenue of $1,214 million, up 10%, and a raised full-year outlook. The operating margin outlook was lowered to 32.1% to 32.3% because of acquisitions. JPMorgan, UBS and Jefferies all trimmed targets, and the shares sit above UBS's $627 and below JPMorgan's $750.
One-Offs
APA (-7.57%) closed at $48.82 as Brent fell 7.63% to $104.77 on progress in US-Iran diplomacy. The refiners' drop on 27 October had the same trigger. The shares had closed at a 52-week high on Friday.
ORCL (-8.76%) closed at $119.22 after filings showed a $20bn raise through bonds and shares, the cap set at last week's investor day. After the close it priced 86,206,897 shares at $116.00. The stock is 38.27% lower this year and near its 52-week low of $114.08.
