Analog Stocks Lag Monday’s Rebound Ahead of Texas Instruments; Broadcom Fell 9.07% Last Week

• Texas Instruments closed Monday at $276.15, down 0.12%, and Analog Devices at $394.35, down 0.28%, per StockAnalysis (Texas Instruments, Analog Devices), while the Philadelphia Semiconductor Index rose 1.6%, per TokenPost. Why it matters: Texas Instruments reports Wednesday against consensus of $2.38 in earnings per share and $5.91 billion in revenue, with analog revenue of $4.76 billion, up 27.7%, per Zacks on Yahoo Finance (October 16), and NXP follows on October 27, per ad-hoc-news, and STMicroelectronics on October 29, per the company; on ChipSentinel’s reading the analog cohort sat out Monday’s rebound because its test is auto-and-industrial demand, not AI funding.
• Broadcom closed Monday at $334.59, up 1.78%, after a 9.07% fall in the week to October 16 that left it at $328.75, per StockAnalysis and per 24/7 Wall St. (October 19), which put fiscal third-quarter AI semiconductor revenue at $16.70 billion, up 221%, and fiscal fourth-quarter AI guidance at $21.70 billion, up 236%. Why it matters: the same article cites chief executive Hock Tan saying “when you co-develop a chip that is optimized for your particular LLM workloads, you will outperform any GPU,” a forward multiple of about 11 against 25 for Nvidia, and a December 9 report against guidance of $34.80 billion in revenue; on ChipSentinel’s reading the custom-silicon case is Broadcom’s answer to a graphics-card shortage like the one in today’s lead.

Micron’s Taoyuan Union Sets a Thursday Strike as Sandisk Rebounds 5.53% After Friday’s Slide

• Micron’s Taoyuan union will strike on Thursday, October 22, timed to a mediation meeting between Micron and a separate Taichung union, with local media reporting a one-day walkout, per Reuters via Investing.com and Focus Taiwan (October 20); the unions want a mechanism that distributes 15% of operating profit to employees, Micron employs about 3,000 workers in Taoyuan and 12,300 in Taichung, and no production impact has been reported. Why it matters: Reuters said the Taoyuan site makes DRAM and HBM, and Invezz noted that more than 75% of fiscal 2027 shipments are committed after a 14.6% share-price fall last week; on ChipSentinel’s reading the one-day Taoyuan action matters less than the Taichung union, the larger site, which has not voted on a strike.
• Sandisk closed Monday at $1,371.12, up 5.53%, after Friday’s 6.85% fall to $1,299.30, per StockAnalysis (history), the largest gain among the memory names cited in TokenPost’s account of Monday’s session. Why it matters: Sandisk reports October 29 and trades at a forward price-to-earnings multiple of 6.27, per StockAnalysis, which also showed the shares about 42% below their 52-week high of $2,354.39 and lower again at the open on Tuesday; on ChipSentinel’s reading, a one-session bounce of this size on a six-times multiple says the market is trading the sector’s direction, not a change in NAND outlook.

Lam Regains 3.13% Before Wednesday’s Report as SK Hynix Backs Its Suppliers With $1.5 Billion

• Lam Research closed Monday at $272.20, up 3.13% after Friday’s 4.87% fall to $263.94, and Applied Materials at $413.11, up about 0.93% from Friday’s $409.29, per StockAnalysis (Lam, Applied). Why it matters: Lam reports Wednesday against consensus of $8.13 billion in revenue and $2.18 in earnings per share, per Investing.com, so on ChipSentinel’s reading the equipment group heads into the first hard order read since Applied’s investor day with Lam up more than the index and Applied barely changed.
• SK hynix, Korea Trade Insurance Corporation and four banks launched a financing program worth 2 trillion won, or $1.5 billion, for small and midsized suppliers of semiconductor materials, parts and equipment, per The Korea Herald (October 19); the insurer will guarantee up to 20 times the capital that SK hynix and the banks contribute, and the first guarantee was issued at the signing. Why it matters: the program eases borrowing costs for the tool and materials vendors that sit behind Korean memory capacity, and on ChipSentinel’s reading it is a customer financing its own supply chain, which tells equipment vendors that memory capacity plans are continuing despite the sell-off in memory shares.

Nvidia’s China Cards Sit Below U.S. Export Limits as Beijing’s Rare-Earth Truce Nears Its End

• Nvidia’s B300 cannot be sold to Chinese buyers under U.S. export controls and H200 exports require case-by-case licenses, while the RTX PRO 5500 is a workstation card that Reuters described as less powerful than both, per Reuters (October 20); the Bureau of Industry and Security and China’s tech ministry did not respond to requests for comment, and an Nvidia spokesperson said “US firms continue to be restricted by a combination of outdated US export controls.” Why it matters: Shenzhen-listed Tansun Technology disclosed in an October 13 filing that it agreed to buy 20,000 of the cards from an unidentified counterparty and warned that shortages or export controls could delay deliveries; on ChipSentinel’s reading the exposure for Nvidia is regulatory timing rather than demand.
• China’s pause on its October 2025 rare-earth export measures expires November 10, and Beijing has not said whether it will extend it, restore selective controls or reinstate the full rules, including provisions reaching foreign-made products with at least 0.1% Chinese-origin rare-earth content by value, per FXStreet (background reading, published October 14). Why it matters: Argus Media’s Maeve Flaherty said “Market participants both inside and outside of China believe that export controls may be reimposed on erbium”; on ChipSentinel’s reading the date is three weeks away and is the next hard policy deadline for equipment and materials suppliers that depend on Chinese inputs.

TS Lombard Warns on Shortage Double-Ordering as Wells Fargo Cuts Allegro and MaxLinear Targets

• Dario Perkins, managing director of global macro at TS Lombard, called semiconductor businesses “notoriously cyclical” and warned that customers who order extra chips during shortages could leave manufacturers with surplus inventory if spending slows, per Invezz (October 20), which reported the comments after Micron’s 14.6% fall last week.
• Wells Fargo cut its price target on Allegro MicroSystems to $45 from $56, keeping an Overweight rating, and on MaxLinear to $78 from $95, keeping an Equal Weight rating, per TheFly headlines on StockAnalysis (Allegro, MaxLinear), both posted on Tuesday morning.

Wednesday Brings Texas Instruments and Lam Research, the Week’s First Hard Demand Reads

• Wednesday, October 21 — Texas Instruments third-quarter earnings call, at 15:30 Central time, per the company.
• Wednesday, October 21 — Lam Research September-quarter results, with consensus of $8.13 billion in revenue and $2.18 in earnings per share, per Investing.com.
