Global memory-chip stocks extended their sell-off as South Korea's KOSPI (^KS11) plunged 7%. SK Hynix (000660.KS) and Samsung Electronics (005930.KS) fell 10% and 8% on concerns over intensifying competition from China, and the two giants account for more than half of the South Korean market's total capitalization. The decline followed a Wall Street chip sell-off, driven by worries about further rate hikes and fears around AI-driven debt financing, with Nvidia (NVDA), Broadcom (AVGO), AMD (AMD) and Intel (INTC) leading the losses. CoreWeave (CRWV) shares dropped more than 15% after a chart of its bond yields circulated on social media, highlighting concerns about its debt-heavy balance sheet. Investors are now looking to TSMC (TSM)'s quarterly results on Thursday, where profits are expected to rise 60%.

- Why AMD Stock Popped on Monday
AMD shares rose 3.6% by 12:30 p.m. ET Monday after TD Cowen analyst Joshua Buchalter reiterated a buy rating and $675 price target, citing growing adoption of agentic AI and production inference workloads where AMD's CPUs are better suited. The stock had lost about 16% over the past two weeks as semiconductor stocks sold off. AMD recently doubled its estimated total addressable market to $220 billion and expects its AI data center CPU sales to rise 70% in 2027. The article notes the stock still trades above 156 times earnings, but at 102x price-to-free-cash-flow and with 60% forecast growth, its price-to-FCF-to-growth ratio is about 1.7 versus a PEG of 2.6.
- Broadcom's Time is Nearing as Neocloud Risk Jolts Nvidia
The author says they bought more Broadcom shares after the stock fell 9.07% in the week ending October 16 to $328.75, citing its role co-designing custom AI chips for large customers. AI semiconductor revenue reached $16.70 billion in fiscal Q3, up 221%, and management guided Q4 to $21.70 billion. The company says it has already secured supply for fiscal 2027 and 2028, generated $13.7 billion in free cash flow, and pays a $0.65 quarterly dividend. The article flags risks such as customer concentration, while noting that NVIDIA has approached insurers about covering losses on loans to neocloud customers. Broadcom reports again on December 9, 2026, against guidance for $34.80 billion in revenue.
- Jensen Huang: “Two Gigawatts to Us Is Like $80 Billion.” 43 New Gigawatts Coming in 2027
Nvidia CEO Jensen Huang said two gigawatts of AI capacity, like the ones Nvidia announced in Australia, are worth about $80 billion to the company, up from about $18 billion per gigawatt previously. He attributed the increase to Nvidia now selling far more of each data center, including networking, CPUs, storage and security, not just GPUs. Citing SemiAnalysis's Dylan Patel on the BG2 podcast, Altimeter Capital's Brad Gerstner said 43 gigawatts of new AI compute will come online next year. At about $40 billion per gigawatt, Nvidia would need around 17 gigawatts to reach the $692 billion revenue estimate for fiscal 2028, though Huang said land, power and data center buildings are the main obstacles to the build-out.
- Chamath: Even Google “Tin Cups for Memory” Thanks to Nvidia. Here’s What Happens Next
Microsoft unveiled its third-generation Maia 300 AI chip on Oct. 12, while Chamath Palihapitiya said on the All-In podcast that even Google is short on memory because Nvidia has locked up most packaging and HBM capacity. Memory makers say their capacity is largely sold out for 2027 and probably much of 2028, and Micron has agreements covering most of its calendar 2027 HBM supply at significantly higher prices. Micron’s capex nearly doubled to $30.7 billion in the year ended Sept. 3, 2026, but most of the increase goes to clean-room space arriving in late 2028 and beyond. The article argues Nvidia, whose gross margin was 71.1% in the year ended January 2026, keeps supply control through roughly 2028, though that window could close sooner if rivals add capacity faster than planned.

- Data Center Buildout Now the Largest Financial Bet in U . S . History – Pagosa Daily Post News Events & Video for Pagosa Springs Colorado
According to Stateline, U.S. data center investment for AI has surpassed all past booms in scale and is crowding out more job-creating sectors. A Columbia Business School report by Stijn Van Nieuwerburgh estimates $10 trillion in investment, with an economic impact of nearly 4% of GDP, almost twice that of railroad expansion in the late 1800s. Many states that granted tax exemptions earlier are now pulling back, as Nevada trimmed abatements and will require data centers to cover energy and water costs. Over three years, Texas ($638 billion), Virginia ($249 billion), Ohio ($169 billion) and Georgia ($160 billion) are projected to see the largest costs, according to Industrial Info Resources. Data center construction value has more than doubled to $85 billion a year while other construction fell 8%, and the profitability of AI remains unproven.

- Is TC Energy (TRP) a Good or Bad Investment at Today's Multiple?
TC Energy trades at 21.19 times next year's expected earnings, closing at $61.74 on October 16 after a 1.5% return over 6 months, versus 10.5% for the Insider Monkey Billionaire Index and 9.3% for the State Street SPDR S&P 500 ETF Trust. The company operates natural gas transmission pipelines across Canada, the United States and Mexico, plus power generation, with a 44.25% operating margin, and latest-quarter earnings rose 18.00% on revenue up 5.70%. The article flags risks including debt at 170.37% of equity, the loss of crude oil pipelines to South Bow in 2024, and volumes that depend on North American gas demand from power and LNG exports. A 4.01% yield is cited as income while the market decides whether the stable business justifies the multiple relative to its growth.
- Should You Buy This Trump AI Stock Ahead of Earnings?
Microsoft (MSFT) reports quarterly results on October 28 and ranks eighth in Trump's latest stock portfolio, after Trump bought the stock five times in August. Bulls point to Azure growth of 43% last quarter, with management expecting about 45% in the current quarter, and to demand that exceeds available computing capacity. Bears cite rising capital spending that Deutsche Bank says could push free cash flow close to breakeven in fiscal 2027, about two-thirds of spending going to short-lived equipment such as chips, and OpenAI making up about 45% of the commercial backlog in the December quarter. The stock trades at 26.75 times forward earnings, a 27% premium to the sector median of 21.01 but 12% below its own five-year average of 30.47, with a PEG ratio of 1.70 versus a sector median of 1.14. The article concludes that investors pay more than for the average tech stock but less than they usually pay for Microsoft.
- What Is Williams' (WMB) Economic Moat, and Is It Steel or Permits?
Williams (WMB) closed at $71.28 on October 16, with a 0.5% return over 6 months, compared with 10.5% for the Insider Monkey Billionaire Index and 9.3% for the State Street SPDR S&P 500 ETF Trust. The article argues its main advantage is the Transco pipeline, which runs from the Gulf Coast up the eastern seaboard, where several attempts to build new pipe have been abandoned after failing to win approvals. A 39.54% operating margin and 21.50% return on equity are cited as evidence of this advantage, although revenue rose only 7.80% last quarter. Limits noted include debt at 200.37% of equity, rules that also restrict Williams' own growth, and a price of 26.81 times expected next-year earnings. The dividend yields 2.95%.
- Marvell Jumps 6% as GF Securities Says Google Chip Delay Won’t Dent Its Position; Broadcom Rises 3%
Marvell shares rose 6% to $241.27 in afternoon trading after a reported delay in Google's next TPU chip, while Broadcom gained 3%. GF Securities analyst Jeff Pu said the delay does not change Marvell's medium- to long-term position in Google's chip supply chain. Marvell reported Q2 FY2027 revenue of $2.74 billion, up 36.5% YoY, with its Data Center segment at $2.17 billion, or 79% of revenue. Google can acquire up to 7% of Marvell shares under a warrant tied to revenue targets, and management expects its custom business to more than double in fiscal 2028. Q3 revenue guidance is $3.15 billion, plus or minus 5%, with non-GAAP gross margin of 57.5% to 58.5%, and the article notes Marvell still needs to convert its Google programs into reported revenue.
- Is ONEOK (OKE) Cheap at 14 Times Next Year’s Earnings?
ONEOK (NYSE:OKE) closed at $93.31 on October 16 and returned 11.4% over six months, versus 10.5% for the Insider Monkey Billionaire Index. The stock trades at 14.49 times next year's expected earnings and yields 4.59%, and revenue rose 52.80% last quarter as the company grew through acquisitions. The article argues that much of this growth was bought rather than built, with only 13.25% of revenue remaining as operating profit and debt at 143.07% of equity. Because a large part of the business involves buying and reselling liquids rather than earning transport fees, the article views the discount as having a reason behind it. It concludes that investors should watch margins rather than revenue.
