Galaxy Digital CEO Mike Novogratz called AI the “biggest bubble of our lifetime” at the Greenwich Economic Forum in early October, yet urged investors to keep buying as the S&P 500 hit a record and NVIDIA's market value neared $6 trillion. He argued AI-linked stocks still look cheap on a P/E basis, that rising long-term borrowing costs won't stop the rally, and that competition with China makes a slowdown in AI development unlikely. NVIDIA reported fiscal second-quarter revenue of $96.22B, up 105.8% year over year, and its market value now stands at $5.21 trillion. Since the panel, the September CPI report released Oct. 14 showed prices up 3.7% from a year earlier, above the 3.6% expected, and the S&P 500 and Nasdaq fell in morning trading. Novogratz says he watches signals such as spiking bond yields, stocks and the dollar falling together, and foreign selling of Treasuries.

- Billionaire CEO : AI Is The Biggest Bubble Of Our Lifetime , But Investors Should Keep Buying During The Melt - Up
Galaxy Digital CEO Mike Novogratz called AI “the biggest bubble of our lifetime” at a Greenwich Economic Forum panel in early October, yet urged investors to keep buying. He says AI stocks still look cheap on price-to-earnings and rising long-term borrowing costs are not enough to stop the rally, while competition with China makes slowing AI development unlikely. His exit signals are stocks and the dollar falling together, spiking bond yields and foreign selling of Treasuries. The article notes NVIDIA revenue rose 105.8% to $96.22B, top-five hyperscalers are projected to spend $1.3 trillion on capex in 2027, and NVIDIA trades near 43 times trailing earnings versus about 29 for Microsoft. After the panel, CPI rose 3.7% against 3.6% expected, and the S&P 500 fell about 0.95%.
- Billionaire CEO: AI Is “The Biggest Bubble Of Our Lifetime,” But Investors Should Keep Buying During The Melt-Up
Galaxy Digital CEO Mike Novogratz called AI the 'biggest bubble of our lifetime' at a Greenwich Economic Forum panel in early October, while still urging investors to keep buying. He argues AI-linked stocks still look cheap on a price-to-earnings basis, that rising long-term borrowing costs are not enough to stop the rally, and that competition with China makes it unlikely AI development will slow. The S&P 500 hit a record and NVIDIA's market value approached $6 trillion, driven by heavy spending, with NVIDIA trading at about 43 times trailing earnings and Microsoft at about 29. Ray Dalio warned rising rates could bring the bubble closer to collapse, while DBS's Hou Wey Fook noted NVIDIA's earnings multiple is near its lowest since 2016. The September CPI rose 3.7% from a year earlier, above the 3.6% expected, and the Fed's late-October meeting is the next key test.
- Corning Is Moving Beyond Fiber Cables. Can AI Networking Pay Off?
Corning (GLW) is extending beyond fiber cables into optical components inside AI systems, having demonstrated optical connectivity with Lumentum and Astera Labs on October 12 and partnered with Nvidia on a planned tenfold expansion of optical connectivity capacity in the US. Its Optical Communications sales rose 32% year-over-year to $2.07 billion in Q2 2026, and management sees a potential $10 billion revenue opportunity by 2030 from a photonics platform, though timing and adoption remain uncertain. Still, the valuation is elevated, with a forward non-GAAP P/E of 44.81x, about 84% above its 5-year average of 24.31x, while analysts expect EPS to grow 30.41% in December 2026 and 33.02% in December 2027. The article notes that slower AI spending or delayed CPO adoption could pressure the stock.
- AI Boom Weakens Interest Rate Impact on Stocks , Citi Says
Citigroup analysts say AI-driven earnings growth and changing investor behavior are weakening the traditional link between bond yields and stock valuations. Citi's fair value model, which uses the 10-year U.S. Treasury yield, estimates the S&P 500 at 17.1 to 22.1 times earnings, while the index trades near 22.4 times, a premium analysts see as signaling optimism and possibly complacency. Since late August, cyclical and defensive stocks have declined, while technology and growth stocks have held up on expected AI-driven profits. Citi adds that rising yields may reflect heavier government debt issuance, and that structural shifts toward defined-contribution plans, target-date funds and foreign buying support equities, though this depends on continued investor participation.
- Is Palantir Stock a Buy Right Now ?
Palantir's stock has risen about 18-fold since its direct listing six years ago, when it began trading at $10 per share and now trades around $186. The article credits its Gotham and Foundry data platforms, its Ontology data model, and its AI Platform, which connects large language models, for the gains. The company has been profitable since 2023 and joined the S&P 500 and Nasdaq-100 in 2024. Analysts expect revenue and EPS to grow at 59% and 70% CAGRs over 2025–2028, and the stock trades at 87 times next year's earnings. Risks flagged include rising interest rates and Treasury yields that could compress its valuation, and a controversial reputation tied to immigration enforcement, mass surveillance and military software.
- Is Palantir Stock a Buy Right Now ? | The Motley Fool
Palantir went public through a direct listing six years ago at $10 per share and now trades at about $186. The article explains its growth through its Gotham and Foundry data platforms, its integration of large AI models such as ChatGPT and Claude, its profitability since 2023, and its inclusion in the S&P 500 and Nasdaq-100 in 2024. Analysts expect revenue and EPS to grow at 59% and 70% CAGRs from 2025 to 2028, and the stock trades at 87 times next year's earnings. Risks include rising interest rates and Treasury yields, its controversial reputation, and indirect competition from Snowflake and Databricks. The author says he would not buy while interest rates keep rising, but would take a second look if the macro environment improves.

- 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.
