Key Highlights

  • Intel (NASDAQ:INTC) fell 28.58% on October 30, 2026, its biggest one-day drop since July 1974, after guiding fourth-quarter Revenue to USD 15 billion to USD 16 billion against about USD 17.1 billion expected.
  • Skyworks Solutions (NASDAQ:SWKS) fell about 12.4% after hours on November 3 after guiding fiscal first-quarter revenue to USD 1.80 billion to USD 1.90 billion against about USD 2.0 billion expected.
  • Marvell Technology (NASDAQ:MRVL) fell 12.72% on November 2 after agreeing to buy Lumentum in an all-stock deal at an implied Enterprise value of USD 115 billion.
  • Micron (NASDAQ:MU) fell 5.78% to USD 833.59 on November 2, about 33.6% below its 52-week high of USD 1,255.00, after a cautious outlook from Japanese memory maker Kioxia.

Intel (NASDAQ:INTC): The Biggest Drop Since 1974

Intel (NASDAQ:INTC) reported third-quarter results on October 29, 2026, after the close. Revenue of about USD 16.5 billion rose roughly 20% and non-GAAP Earnings were USD 0.52, with Data Center and AI revenue up 78% to about USD 7.3 billion. The problem was guidance: fourth-quarter revenue of USD 15 billion to USD 16 billion and earnings of USD 0.25 fell far short of about USD 17.1 billion and USD 0.43 expected, and non-GAAP gross Margin is expected near 38% against 44.1% in the third quarter. The shares fell 28.58% on October 30, wiping out about USD 140 billion of Market Value in one published estimate, and fell 37% over three sessions. Intel expects the PC market to shrink about 12% in 2026 as memory prices rise, and an Israeli factory accident is expected to cut fourth-quarter revenue by USD 300 million to USD 600 million, depending on the account. The stock rose between 1% and 3.4% on November 3, but bounces from oversold levels can be short-lived. Capital spending is expected near USD 20 billion, and the company does not expect positive free Cash Flow for the full year, so the weak outlook comes alongside heavy investment. Analysts rate the stock Hold on average, with published targets from USD 70 to USD 160, a wide spread.

Skyworks Solutions (NASDAQ:SWKS): An In-Line Quarter, a Weak First Combined Guide

Skyworks Solutions (NASDAQ:SWKS) reported on November 3, 2026, for the quarter ended October 2, its last as a standalone company. Revenue of USD 1.05 billion and adjusted earnings of USD 1.28 a share were roughly in line, each beating by about a cent. The surprise was the first-quarter outlook after the Qorvo merger: revenue of USD 1.80 billion to USD 1.90 billion and earnings of USD 1.25 compare with about USD 2.0 billion and USD 1.50 expected. The midpoint of USD 1.85 billion is about 7.5% below the consensus level, simple arithmetic on two published numbers. Smartphone revenue is expected to fall by a low-teens rate sequentially. The shares fell about 12.4% after hours, with other accounts citing declines of 13% to 17%, so the figure is approximate until regular trading confirms it. Skyworks Solutions (NASDAQ:SWKS) targets at least USD 500 million of annual cost synergies within 24 to 36 months, but integration brings costs and the combined company leans heavily on smartphones, a category facing memory-cost pressure. Because the Merger closed in early October, year-over-year comparisons will be distorted for several quarters, and analysts may disagree about the underlying growth rate.

Marvell Technology (NASDAQ:MRVL): Dilution Fears on an All-Stock Deal

Marvell Technology (NASDAQ:MRVL) agreed on November 2, 2026 to buy Lumentum in an all-stock deal at a fixed 4.500 Marvell shares per Lumentum share, an implied enterprise value of USD 115 billion. Marvell holders would own about 67% of the combined company, and closing is expected in the first half of 2028. The company identified more than USD 1 billion of annual run-rate cost synergies and expects non-GAAP earnings accretion in year one after closing. The shares fell 12.72% on November 2. BofA cut Marvell to Neutral from Buy and its target to USD 225 from USD 400, citing roughly 50% share-count dilution, a long regulatory review and channel conflict. Because the exchange ratio is fixed, the value Lumentum holders receive moves with the Marvell share price, which has already fallen. A review that includes China, integration of two large engineering organizations and customer conflict are the main risks. The company also preliminarily reported fiscal third-quarter revenue and narrowed its guidance range to plus or minus 2%, which analysts will weigh against the deal terms. Lumentum reported fiscal first-quarter revenue of USD 1.26 billion, so the target is growing fast.

Micron (NASDAQ:MU): A Cautious Peer and AI Spending Worries

Micron (NASDAQ:MU) closed at USD 833.59 on November 2, 2026, down 5.78% from USD 884.74, on Volume of about 29.9 million shares against a 30-day average of about 26.3 million, per published market data. Coverage tied the drop to a cautious December-quarter outlook from Kioxia, the Japanese flash memory maker, and to renewed worries about AI spending. A second tracker showed a smaller intraday decline of about 3%, so the size depends on the timestamp. The fundamentals remain extraordinary: fiscal fourth-quarter revenue of USD 54.23 billion against about USD 11.3 billion a year earlier, with a GAAP gross margin of 86.8%, and fiscal first-quarter 2027 guidance of USD 61.5 billion. The mechanism cuts both ways, because when a supplier signals slower price increases, investors discount peak profits quickly. Micron (NASDAQ:MU) rose about 2.6% on November 3. Net capital spending was USD 10.77 billion in one quarter, which raises the stakes if Demand softens. Published commentary also points to slower DRAM and NAND price increases and to rising capacity at Chinese rivals, though Micron has not confirmed either point.

Where Things Stand

Each of these chip names was hit for a different reason: a guidance shock at Intel, a weak first combined outlook at Skyworks, dilution fears at Marvell and a peer's caution at Micron. The common thread is that expectations were high, so the market punished any sign that growth or margins would slow. Intel (NASDAQ:INTC) shows how quickly a stock that more than doubled in 2026 can fall. Skyworks Solutions (NASDAQ:SWKS) must prove the Qorvo combination improves margins. The next evidence is fourth-quarter reports, memory price data and the regulatory path for the Marvell and Lumentum deal. These drops are not forecasts, and rebounds can fade.
