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 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, 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.

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.

The author says he would not buy while interest rates keep rising, but would take a second look if the macro environment improves.

- More than US$1 billion set to flow into stocks: has the time to deploy arrived?
BSC (BIDV Securities) maintains that valuations across many sectors have become more attractive, making now a reasonable time to allocate to stocks for the medium to long term. Market-wide profits rose 50% year on year in Q2 2026, and BSC raised its 2026 profit growth forecast to 26% and expects 12% growth in 2027.

- Securities firm names 2 companies directly benefiting from proposed fertilizer export tax cut
MBS views the Ministry of Finance's proposal to cut export tariffs on urea, superphosphate and sulphate of potash (SOP) from 5% to 0% as a positive factor for the fertilizer sector, though the effective date has not yet been set. Đạm Cà Mau (DCM) is seen as the biggest beneficiary, with estimated savings of about VND 203 billion per year (9.2% of 2025 pre-tax profit), as urea accounted for about 59.7% of its sales volume in the first eight months of 2026. Đạm Phú Mỹ (DPM) is estimated to save about VND 93 billion per year (6.9%), a smaller benefit than DCM. LAS's benefit is limited, DDV does not benefit directly, and BFC could face cost pressure if domestic urea prices rise.
- Why Palantir Technologies Stock Rallied Today
Palantir Technologies (PLTR) shares rose sharply on Monday morning, reaching as much as 5.9% and still up 5.5% as of 12:19 p.m. ET.

However, given Palantir's triple-digit profit growth, its PEG ratio is 0.5.
