The article argues that S&P 500 returns in recent years have leaned heavily on AI spending by large technology companies such as Microsoft, Alphabet, Amazon and Meta. On Oct. 25, Elon Musk warned on X that financing is tightening for companies building AI data centers, particularly neoclouds such as CoreWeave and Nebius, and predicted that “200+ neoclouds” would see “guppy-level death and consolidation,” suggesting 2027 could bring financial distress and a slowdown in data center investment. The article notes that eight technology giants make up about 36% of the index, so a 30% drop in those eight alone would translate into roughly a 10% decline in the S&P 500. It adds that the bigger risk is that investors have already priced in more AI success than the industry can deliver, which could compress valuation multiples for growth stocks if AI spending slows.

- 3 Founder Led Stocks With Up To 31% ROE
The article says high interest rates have not cooled the AI investment boom, which is rewarding founders who remain deeply involved in daily decisions. It profiles newcleo (NWCL), which develops lead-cooled fast reactors and MOX nuclear fuel under founder CEO Stefano Buono and generates about €44 million from electric equipment, with a €1.77b market cap; it notes the premium valuation, losses and balance sheet risk tied to that leadership. It also covers Tesla (TSLA), which generates about US$90.8b from automotive and US$12.8b from energy generation and storage, with a US$1.40t market cap, and says much of its valuation depends on Elon Musk's vision across AI, robotaxis, humanoid robotics and battery storage, as well as future profitability and capital access.
- 3 Glorious Growth Stocks to Buy Hand Over Fist If the Stock Market Crashes
The author notes the S&P 500 hit a fresh record earlier this month while volatility rises over doubts about AI infrastructure spending, and argues a downturn could present an opportunity. Elon Musk predicted that over 200 neoclouds, such as CoreWeave, might not survive as funding dries up for firms without revenue independent of AI data centers. The article highlights CrowdStrike, whose annual recurring revenue rose 25% to $5.84 billion in its fiscal 2027 second quarter, though its 49.1 price-to-sales ratio is the highest in cybersecurity. Atlassian, with a price-to-sales ratio of 9 against a 10-year average of 18.3, is cited for AI agents grounded in its ecosystem using 48% fewer tokens and producing answers 44% more accurate. Nvidia is named as likely more exposed than any other company to a slowdown in AI infrastructure spending.
- Amazon Stock Costs More Than the Market. I'd Still Buy It for the Next 5 Years.
Amazon shares rose about 5% on Monday but trade near $262, roughly 8% below their August 3 record close of $284.02. The author argues the right benchmark for today's buyers is an S&P 500 index fund, which compounded about 10% a year with dividends reinvested from 1928 through 2025, and expects Amazon to beat it over five years because profits are growing faster than sales. Operating income rose from $22.9 billion in 2020 to $93.7 billion in the 12 months through June, up 23%, with AWS contributing $54.7 billion, about 58% of the total. Net purchases of property and equipment rose $66.1 billion over the trailing 12 months, mainly for AI, and free cash flow over the same span was a $7.6 billion outflow. The author expects earnings to grow about 15% a year through 2031 and sees the stock beating the index by a couple of percentage points a year, despite trading at about 25 times expected 2027 earnings.
- Prediction: Oracle Stock Trails the S&P 500 Through 2030
Oracle stock, near $130 at writing, is about 60% below its Sept. 10, 2025 record close of $328.33 and down 33% this year, while the S&P 500 returned about 13% through September. The author argues Oracle's cash flow matters more than its cheap-looking earnings: fiscal 2026 capital spending of $55.7 billion exceeded operating cash flow of $32.0 billion, and management guides to $90-95 billion of capex this year. Free cash flow was still negative in the fiscal first quarter, the sixth straight negative quarter, and management gave no timeframe for a return to positive. Oracle is covering the gap with stock sales and about $40 billion of planned debt and equity, which has raised share count and interest costs. The author expects the stock to trail an S&P 500 fund through 2030, despite trading at about 16 times expected earnings.
- The Stock Market Is Echoing a Warning From the Dot-Com Bubble, and History Says Investors Should Make This 1 Move
The S&P 500 has hit record highs and gained about 100% over the past three calendar years plus 2026 to date, driven largely by enthusiasm for AI stocks. Nvidia has jumped 900% in five years and Micron 200% this year alone, while Amazon, Microsoft, Alphabet and Meta are expected to spend more than $700 billion this year. The article highlights the Buffett indicator, the total value of U.S. listed companies relative to GDP, at 238%, its highest ever and well above about 148% during the dot-com bubble. Although the S&P 500 fell after previous peaks in this indicator in 2000 and late 2021, it recovered and gained over the following years, so the author advises investors to hold their positions for the long term.
- Warren Buffett and Broadcom CEO Issue a Similar Blunt Warning to Wall Street. Here’s What Investors Should Do Next, According to a Key Buffett Investing Principle.
The S&P 500 has hit record highs, rising 78% over the past three calendar years and heading for a 14% gain this year, largely driven by AI stocks. Warren Buffett, in a CNBC interview at the May shareholders’ meeting, likened markets to “a church with a casino attached” and said people have never been in a more gambling mood. Broadcom CEO Hock Tan said many AI investors set extreme expectations and are almost like they are in a casino because they don’t truly understand what they are investing in. The S&P 500 Shiller CAPE ratio recently reached 41, its highest ever, indicating stocks are historically expensive. Citing a key Buffett principle, the article advises investing in quality companies you know well so you can set reasonable expectations for their growth and stock performance.

- European Central Bank keeps key interest rate on hold at 2.5%
The European Central Bank held its deposit facility rate at 2.5% on Thursday, as expected, after a 25 basis point hike in September, even though euro zone headline inflation rose to 3.8% last month, the highest since September 2023. The Governing Council said rising energy prices pose upside risks to inflation and downside risks to growth, while underlying inflation and wages are broadly stable and financing conditions have tightened. Energy price inflation reached 18.8% amid Middle East turbulence. Deutsche Bank's Mark Wall said the policy path is harder to predict and expected one more hike to 2.75% in December, probably the end of the hiking cycle, while Christine Lagarde is still president. He added that the institution is bigger than any one person, but uncertainty remains about decisions next year after Lagarde's announced departure.

- Private, fast USDT is coming to Bitcoin. Can it compete with Ethereum and Tron?
Utexo, a Dubai-based blockchain startup, plans to bring Tether's USDT back to Bitcoin after a three-year hiatus through the RGB protocol, which keeps transaction data off-chain. The public launch is scheduled for Nov. 28, with Lightning Network support planned for Q1 2027. USDT first ran on Bitcoin in 2014 through the Omni protocol, but Tether halted issuance in August 2023 citing declining usage, and later led Utexo's $7.5 million seed round in March. With $300 billion of stablecoin supply already on networks such as Ethereum and Tron, co-founder Viktor Ihnatiuk says the Bitcoin version's advantages are speed and privacy. Utexo Mint locks USDT0 on Arbitrum before minting an equivalent amount of USDT on Bitcoin, so its security also depends on the mechanisms connecting the two networks.
- Brazil’s Halloween eve crypto deadline brings more tricks than treats
Brazil's crypto exchanges face a Friday deadline to apply for authorization under the framework introduced in November 2025 under the central bank BCB. Exchanges that apply on time can keep operating while their applications are reviewed, a process that can take up to two years, while companies that miss the deadline must stop providing services within 30 days. Lawyers say minimum capital requirements of 10.8 million reais ($2 million) to 37.2 million reais, plus audits and anti-money laundering controls, could make compliance unviable for smaller exchanges. Questions remain over how to identify self-custody wallets, the $100,000 limit on certain international transfers and reporting thresholds, and the BCB had not responded at publication.
