Cerebras Systems (CBRS) fell 10% after short seller Culper Research said its wafers break down after about two years, erasing Tuesday's 10% gain on a deal to offer its systems on Oracle's cloud. Culper also flagged that draft IPO filings through December 2025 gave systems useful lives of 1.5 to 3 years, while a range of 3 to 5 years appeared four months later without explanation. Longer lives mean lower depreciation and fatter margins, and gross margin rose from 11.7% in fiscal 2022 to 42.3% in fiscal 2024 before easing to 39.0% in fiscal 2025. The article says the two-year claim is unproven, and Cerebras trades at about 18x forward sales against a 37x average since it listed in June.

- Once Wall Street’s Darling, Cerebras Stock Is Struggling
- Is Nvidia Still the Best AI Stock to Buy in 2026, or Is This Challenger?
The article argues that Nvidia remains the better AI stock for most investors, citing its dominant position in AI chips, triple-digit revenue and profit growth in its latest quarter, and guidance for a 70% revenue increase next fiscal year. Nvidia's stock, which has soared more than 900% over five years, trades at about 24 times forward earnings. It contrasts Nvidia with Cerebras Systems (CBRS), which recently completed its IPO and makes a Wafer-Scale Engine chip 58 times the size of the Nvidia B200, claiming up to 15 times faster inference than GPU solutions. Cerebras' cloud and other services revenue jumped 281% to $126 million last quarter, but its shares, which opened at $350, are down 58% and trade below the $185 IPO price. The author sees Cerebras as an opportunity only for aggressive investors.
- Should You Hold on to Cerebras Stock Despite Its 25% One-Month Dip?
CBRS shares plunged 25.3% over the past month, underperforming the Zacks Business Services sector's 0.3% gain and rivals NVIDIA (up 1.6%) and Advanced Micro Devices (up 9.7%). Near-term margin pressure from renting systems back from customers to expand cloud capacity, along with heavy reliance on OpenAI, has weighed on the stock. Core revenue jumped 103% year over year to $209.9 million in Q2 2026, with core cloud and other services revenue up 287% to $127.7 million, and remaining performance obligations stood at $25.4 billion. Core gross margin fell 590 basis points sequentially to 40.6% in Q2, and the company expects Q3 to be the trough, with core gross margin guided at 38-40%. Management expects margins to recover as higher-cost rented capacity is replaced by Cerebras-owned systems.

- Nvidia's relationship with China just got even more complicated as report says Jensen Huang was target of spy plot
Nvidia has struggled to gain a foothold in China because of US Commerce Department export restrictions in place since 2022. The New York Times reported that US intelligence believes Alice Huang, a leader at Nvidia customer Megaspeed with a well-documented relationship with Jensen Huang, acted as an intelligence asset and passed information to China's governing party, raising questions about information leakage from Nvidia. In December 2025, the Trump administration allowed some H200 chip exports after a $5 million lobbying push during the year, but H200 sales made up less than 1% of Nvidia's $89 billion second-quarter data center revenue, as Beijing blocked Chinese buyers from purchasing Nvidia chips. Nvidia said its forward outlook includes no China data center compute revenue. The article also describes a black-market trade smuggling chips through Southeast Asia and Blackwell B300 chips being openly sold on Douyin at millions of US dollars per server.
- These 2 Stocks Have Skyrocketed in 2026. Here’s Why I’d Stay Away
Moderna (MRNA) shares are up 570% and Iovance Biotherapeutics (IOVA) up 433% so far this year, following clinical and commercial progress. The author argues Moderna's $77 billion market cap already prices in its personalized cancer vaccine intismeran autogene despite positive Phase 3 results; assuming $5 billion in profits by 2031 and a 12% required rate of return, the company would need a forward P/E of 27.1 to justify today's valuation. For Iovance, second-quarter revenue rose almost 66% to $99 million on Amtagvi sales and loss per share narrowed to $0.11, but trailing 12-month revenue was $324.9 million against a $6.6 billion market cap. The author highlights manufacturing, administration and clinical-regulatory risks, and is skeptical Iovance can outperform the broader market over the next five years.

- Alphabet: 3 Key Takeaways for Long-Term Investors
Alphabet reported third-quarter 2026 revenue of $127.6 billion, up 25% year over year, as demand grew for custom hardware and cloud services amid scaling AI tools. Google Cloud revenue rose 103% to $30.7 billion, with elevated demand for TPUs and 18 product lines each generating over $1 billion in annual revenue. Search query growth reached its highest rate in five years as users adopted generative AI tools, and ads are being integrated into these search interfaces. Full-year 2026 capex guidance of $195–205 billion was unchanged, with 65% of infrastructure spend going to servers and networking hardware with estimated six-year useful lives, and capex is expected to rise significantly in 2027. Management said it expects ROIC to remain meaningfully above its cost of capital throughout this investment cycle.
- AMD Has Ripped 170% This Year: Is It Too Late to Buy?
AMD stock is up 170% in 2026, driven by two record data center quarters and a Meta deal for up to 6 gigawatts of Instinct GPUs. Second-quarter revenue rose 50% to $11.5 billion, data center sales more than doubled to $6.7 billion, and AMD guided to about $13 billion for the third quarter. Analysts expect normalized EPS to rise from $7.61 this year to $15.85 in 2027, while the forward P/E has fallen from a 67x peak to 50x. The author sees the main risk as AMD helping fund some of its own demand through a lease guarantee, up to $5 billion pledged to Anthropic, and warrants of up to 160 million shares apiece for OpenAI and Meta. The author judges AMD isn't too late to buy, with the Nov. 3 report as the key test.
- Crocs Lifts Outlook as Growth Shifts Overseas: Rapid Earnings Reaction
Crocs raised its full-year outlook for a third consecutive time as quarterly revenue rose 4.6% to $1.04 billion, helped by overseas growth and a return to growth at HEYDUDE. Adjusted operating income grew 11.7%, and adjusted gross margin rose to 60.3% from 58.5%. A one-time $64 million tariff refund was excluded from adjusted earnings, while adjusted diluted EPS grew 26.4% to $3.69, helped by a diluted share count down about 11%. Crocs brand revenue rose 4.4% to $873 million, with international up 11.8% and North America down 2.1%; HEYDUDE revenue rose 6.1% to $170 million. Management now expects full-year revenue growth of about 3%, up from 1% to 2%.
- Palo Alto Soars 14% in a Week as CEO Warns of AI’s “Nuclear Sort of Bomb”
Palo Alto Networks (PANW) stock rose 14% over the past week while the S&P 500 was roughly flat, as AI helped uncover software flaws and an Evercore survey showed security budgets firming. The broader cybersecurity group rallied too, with CrowdStrike (CRWD) up 11%. The author argues the valuation is already full: the forward P/E reached 96x on Oct. 27 versus a five-year average of 57x, and the stock closed Oct. 28 just under the $399 average analyst target. The main risk cited is that major AI players, such as Amazon with AWS Continuum, may sell defensive tools themselves. The author says the fiscal first-quarter report, which will test next-generation security ARR, is the key event, and rates the stock as a hold for now.
- Why FTAI Aviation Stock Popped on Thursday
FTAI Aviation (FTAI) shares rose 14.61% after the aircraft leasing company reported third-quarter results, with revenue of $977.7 million, up 46.6% year over year, and profit of $150.6 million, up 28%. EPS rose 30% to $1.43, a pleasant surprise for investors who had sold the stock this year, though the shares are still down 10% over the past year. FTAI doubled its buyback authorization to $1 billion, which could retire more than 6% of shares outstanding if fully executed. The author is skeptical, noting the company had about $386 million on its balance sheet against more than $3.45 billion of long-term debt and burned nearly $516 million in negative free cash flow in the first half, per S&P Global, so buybacks would likely require more borrowing.
